Opis:

The studies were conducted between 1999 and 2001 in two hunting regions. Larval alariosis was revealed in the boars only in one of the studied regions. In this region, the results of the parasitological studies, conducted towards A.alata in the direct host (domestic dogs) and indirect hosts (snails: Planorbis planorbis and Anisus vortex as well as frogs: Rana temporaria and Rana terrestris) were also positive. The lack of the host snails A.alata in the other region might have resulted from no presence of the parasite in the boar.

Opis:

There are numerous cases of dermatitis described world-wide and resulting from the influence of the furcocercaria of the bird schistosome. The host snail species of the schistosome, producing thousands of furcocercaria are common in our country. But, because of too general symptoms of dermatitis resulting from the influence of the schistosome of the larvae, there are many unrecognisable cases. The reaction described was typical of a twenty-seven-year-old man collecting snails in the Piechota Bay in Gostynin (the Province of Kuyavia and Pomerania). In that reservoir, individuals of Lymnaea stagnalis were found, which were infected with sporocysts and furcocercaria of Trichobilharzia ocellata. In the laboratory conditions, a high expulsion of cercaria was observed, which amounted to over 8000 larvae per snail.

Opis:

The aim of the study was to determine a reason for failing health condition and deaths amang the ostriches in the newly-established breeding farm situated within the boundaries of Toruń Voivodship. Both initial observations and examinations of three alive and two dead birds presupposed an appearance of ectoparasitical disease. The autopsies were performed and the specimens for bacteriological and perasitological studies were subsequently obtained. The ectoparasitically-directed studies were the only positive result; the individuals of Cnemidocoptes mutans and unrecognised Acarina species were found. Although the overall treatment (Ivomec) and breeding-rooms extennination of vermin (Neguvon 2%) were held, health conditions of the ostriches failed to improve and, as a result, all the birds died. The breeding farm was closed down wich the owner having suffered financially. The study allowed to draw conclusions concerning reasons for Acarina invasion and subsequent deaths among the birds.

Opis:

Parasitical invasions constitute a serious veterinary-economic problem in pheasant breeding. The studies were carried out between 1995-1997 in a big breeding centre situated in the Middle Pomerania region, where the basic flock amounted to 1000-1200 bird individuals. The aim of the study was to determine a condition of the pheasants' affliction with nematodes, reasons for the invasion and possibilities of a decrease in the losses thus brought about. In the subsequent years, the flock affliction reached the following proportions: 40% in 1995, 42% in 1996, and 68% in 1997. Between 1995 and 1996, the findings revealed eggs of the nematode Capillaria sp (C. anatis and C. phasianina) in their faeces, with less frequent cases of Trichostrongylus tenuis, Heterakis isolonche and Syngamus trachea. Between 1995-1996 40% deaths in the afflicted flock were brought about by Syngamus trachea whilst in 1997 syngamosis resulted in 80% deaths among the afflicted birds. To determine reasons for the confirmed nematode invasion in the studied period during which all the requirements were fulfilled in the pheasant breeding, conclusions were drawn on the basis of the study. Also, preventive measures were suggested to stop any further appearance of syngamosis or losses due to other endoparasites, as those in 1997.

Opis:

The studies were carried out between 1997-1999 within the administrative district of Toruń. Forty sports pigeon breeders together with their pigeons were under study annually. The collected materiał allowed noticing the following issues: in 1997 and 1998 the Argas reflexus (Fabricius, 1794) was present in dovecotes (individuals) and the breeds' owners were pricked. In 1998 numerous specimens of the A. rejlexus were obtained from the materiał from the sanitary-epidemiological station. The specimens were collected from the bodies of the people, family members and from their flat located on the highest third floor of the old house. In the miteinfected dovecotes and in the old houserooms, the following steps were suggested: mechanical cleansing, whitewashing, disinfecting, and triple disinsecting, with fourteen-day-long intervals. The people with the symptoms of acariosis were subjected to treatment with calcium, antiallergic, and anti-fever mixtures, and, in some cases, cortisone ointments were applied. In spite of a considerable growth in the symptoms, the used methods turned out to be successful in all the studied cases.

Opis:

The studies were conducted in three big fully automaticised egg-laying farms within the boundaries of Toruń Voivodship, where Dermanyssus gallinae (DE GEER 1778) was present. The increased invasion of the parasite on one of the farms resulted in the presence of all clinical symptoms of dennanyssosis. A considerable decrease in the body weight, anaemia and organism exhaustion were observed. A growth in the hens' death rate from 1% (when they were not contaminated) to 4% was observed. There was also a decrease in egg-laying, particularly in its top phase. When breeding farms are not contaminated, egg-laying amounts nonnally to 91-93%, whereas in the contaminated farm the percentage lowered to 80-82%. The hens' death rate, a decrease in the egg production as well as a fall in the productive cycle by two months resulted in economical losses suffered by the farm owner. Having excluded the treatment costs, the sum amounted to c. 36,000 PLN in a single production cycle. To fight the parasite effectively, cleansing frequency, desinfecting with Wirkon and Pollena Jod K or caustic soda, and disinsectization with Neguvon and Alfasep 10WP were increased.

Opis:

Two different tissue phantoms of the left ventricle to imitate a beating left ventricle were developed: first was prepared using a sponge material and second phantom was constructed using a polyvinyl alcohol material modeled into a homogeneous hollow cylinder: approximately 10 cm and 12 cm in length for the first and second phantom, respectively. Both phantoms were 5 cm in diameter, with a wall thickness of 1.0 cm. Additionally, a small part of the wall of the second phantom was processed to simulate the stiffness of myocardial infarction. The phantoms were connected at the end to an adjustable external pump. The pulse volume inside the cylinder was set between 12 to 50 ml at rates of 40, 60, 100, 120 beats/minute. The phantoms were immersed in water for ultrasound scanning with two different insonation angles (90 and 65 degrees). Strain and strain rate were measured with different combinations of angles and pulse rates. The main aim of this work was to develop the new method for validation of the human infarct wall strain calculation procedures using the speckles tracking.

Opis:

More and more attention is paid nowadays to the quality and durability of the applied cement slurries. Apart from the appropriate rheological, technological and strength parameters, the slurry should be resistant to the strongly mineralized reservoir waters. Appropriate phase composition of cement slurries, especially high CSH content is responsible for the change of pore structure in the cement slurry; the number of fine gel pores which are not available for the fluid increases and the number of capillary pores responsible for the transport of corrosive factors inside the cement slurry decreases.The use of nanosilica as an additive improving the properties of cement slurries has recently gained popularity. Bearing in mind these properties of nSiO2, there were conducted laboratory experiments on the use of organic nanosilica for cement slurries based on Portland cement CEM I 52.5 R.

Investigations of the photoluminescence of PbS-EuS superlattices deposited on (111)BaF$\text{}_{2}$ substrates are presented. Quantum-size and deformation effects in photoluminescence spectra are observed. The strain-induced gap shift and valence-band offset is determined from experimental results. A strong stimulated photoluminescence with relatively low threshold was observed. It was found that the photocarriers generated in EuS barrier strongly affect the population of PbS subbands.

The present work concerns the sonographic model of the left ventricle (LV) examined in the Computed Tomography (CT) environment and compare radial strain calculations obtained by two different techniques: the speckle tracking ultrasonography and the Multislices Computed Tomography (MSCT). The Left Ventricular (LF) phantom was fabricate from 10% solution of the poly(vinyl alcohol) (PVA). Our model of the LV was driven by the computer-controlled hydraulic piston Super-Pump (Vivitro Inc., Canada) with adjustable fluid volumes. The stroke volume was set at of 24ml. The fluid pressure was changed within range of 0-60 mmHg, and the pulse rate was of 60 cycles/per minute. The relationships between computer controlled left ventricular wall deformations and its visualizations of the echocardiographic and CT imaging, both in the normal and pathological conditions were examined. The difference of assessment the Radial Strain between two methods was not exceeding 1.1%.

Opis:

Mistletoe (Viscum album L.) is a semi−parasitic plant and, as long as it is not present in large quantities, it does not pose a lethal threat to trees. Due to its ability to carry out photosynthesis, its effect on the host is negligible. However, recent droughts have made heavy impact on forests and mistletoe in recent years began to appear on a larger scale in regions and in places where it has never been a threat before. For this reason, there is an urgent need to broaden our knowledge about this species. This work includes a review of the literature on the biology and ecology of mistletoe. The main purpose of this research is to analyze the methods for assessing the number of mistletoe on individual trees and in the stands as well as to prepare new method adapted to Polish conditions. New method that was proposed is based on random sample plots, each consisting of 15 trees on which impact of mistletoe is assessed. On every sample plot the mistletoe occurrence, location in the crown, estimate of the percentage within the crown and the number of mistletoe on a tree is assessed. In addition, for further analysis, information on stand (forest habitat type, site index) as well as measured trees (age, diameter, Kraft class, crown length, loss of assimilation apparatus, crown type) levels is recorded.

Opis:

Kynurenic acid (KYNA), an endogenous neuroprotectant formed along the kynurenine pathway of tryptophan degradation, is a selective ligand of the GPR35 receptor, which can be found on the surface of various populations of human immune cells. In infections and inflammations, KYNA produces an anti-inflammatory effect through this receptor, by depressing the synthesis of reactive oxygen species and pro-inflammatory cytokines. However, it is still unrecognized whether receptors for kynurenic acid are also localized on immune cells of poikilothermic animals, or whether KYNA is able to affect these cells. The objective of this study has been to determine the effect of different concentrations of kynurenic acid (12.5 μM to 10 mM) on the viability and mitogenic response of lymphocytes and on the activity of phagocytic cells isolated from blood and the spleen of rainbow trout. The results imply low toxicity of kynurenic acid towards fish immune cells, and the proliferative effect observed at the two lowest concentrations of KYNA (12.5 μM and 25 μM) seems indicative of endogenous kynurenic acid being capable of activating fish lymphocytes. Non-toxic, micromole concentrations of KYNA, however, had no influence on the mitogenic response of lymphocytes nor on the activity of phagocytes in rainbow trout under in vitro conditions. There is some likelihood that such an effect could be observed at lower, nanomole concentrations of KYNA.

The objective of this study was to evaluate the effect of HMB on selected parameters of the humoral immunity in calves. The experiment was performed on 14 calves aged 30 ± 2 days, divided into two equal groups of control (group K) and experimental (group H) animals. The feed administered to the experimental calves was supplemented with HMB at 40 mg/kg BW, whereas the control calves were administered standard farm-made feed without supplementation. Blood was sampled from the jugular vein immediately before the experiment (day 0) and on experimental days 15, 30 and 60 to determine the following immunological parameters: total protein levels, gammaglobulin levels, lysozyme activity and ceruloplasmin activity. An analysis of the results obtained revealed a significant increase (p < 0.05; p < 0.01; p < 0.001 respectively) in gammaglobulin levels and lysozyme activity throughout the entire experimental period, an increase (p < 0.05; p < 0.01 respectively) in ceruloplasmin activity on experimental days 15 and 30, but no changes in serum total protein levels of calves administered HMB as compared to those found in the control group.

We present the results of ferromagnetic resonance studies of the thickness dependence of magnetic anisotropy in 2 series of EuS-PbS multilayers grown on (111) BaF$\text{}_{2}$ and (100) KCl substrates with the EuS thickness varying in the range d=6-70 Å. The anisotropy constant K was found to follow the dependence K(d)=K$\text{}_{V}$+2K$\text{}_{S}$/d , with the surface term K$\text{}_{S}$ larger for layers grown on BaF$\text{}_{2}$ as compared to KCl. This difference is discussed in terms of different thermal stress-induced distortions of cubic crystal lattice of EuS. We found that the thickness of EuS layer required for the perpendicular (to the layer) magnetization is d ≤ 2-3 Å, i.e., it is below 1 monolayer.

Opis:

A finite element analysis has been carried out to investigate flow patterns and loads on silos either with a ralatively steep hopper, or with a shallow hopper but in the presence of an insert. A Lagrangian-Eulerian approach was first adopted to simulate the material flow pattern, with the precondition that mass flow was obtained. It was then attempted to predict the loads exerted by granular materials on the walls of such silos. The load on the insert was also simulated. Techniques such as the adoption of adaptive meshes and filleting along sharp corners were applied in the analysis to overcome the difficulties usually encountered with large deformations in the FEM and the mathematic singularity presented by the abruptness of geometry. Filleting proved to be necessary to bring down the pressure peak at the transition level. The insert took over a significant part of the loads. Comparison with the classic theories have confirmed that the loads predicted on the wall agree quite well with the theoretical results in the silo's cylinder section, but that differences exist in the hopper section; the difference is greater when the hopper is shallower. It has also shown the limitations of predicting flow patterns of granular materials with the traditional elastic-plastic model; a more advanced model is needed.

Opis:

The use of therapeutic ultrasound continues to grow. A focused ultrasonic wave can increase the tissue temperature locally for the non-invasive cancer treatment or other medical applications. The authors have designed a seven-element annular array transducer operating at 2.4 MHz. Each element was excited by sine burst supplied by a linear amplifier and FPGA control circuits. The acoustic field, generated by a transducer was initially numerically simulated in a computer and next compared to water tank hydrophone measurements performed at 20, 40 and 60 mm focal depth. The results showed good agreement of the measurements with theory and the possibility to focus the ultrasound in the preselected area. The total acoustic power radiated by the annular array was equal to 2.4 W.

Opis:

Recently a new technology of piezoelectric transducers based on PZT thick film has been developed as a response to a call for devices working at higher frequencies suitable for production in large numbers at low cost. Eight PZT thick film based focused transducers with resonant frequency close to 40 MHz were fabricated and experimentally investigated. The PZT thick films were deposited on acoustically engineered ceramic substrates by pad printing. Considering high frequency and nonlinear propagation it has been decided to evaluate the axial pressure field emitted (and reflected by thick metal plate) by each of concave transducer differing in radius of curvature – 11 mm, 12 mm, 15 mm, 16 mm. All transducers were activated using AVTEC AVG-3A-PS transmitter and Ritec diplexer connected directly to Agilent 54641D oscilloscope. As anticipated, in all cases the focal distance was up to 10% closer to the transducer face than the one related to the curvature radius. Axial pressure distributions were also compared to the calculated ones (with the experimentally determined boundary conditions) using the angular spectrum method including nonlinear propagation in water. The computed results are in a very good agreement with the experimental ones. The trans- ducers were excited with Golay coded sequences at 35–40 MHz. Introducing the coded excitation allowed replacing the short-burst transmission at 20 MHz with the same peak amplitude pressure, but with almost double center frequency, resulting in considerably better axial resolution. The thick films exhibited at least 30% bandwidth broadening comparing to the standard PZ 27 transducer, resulting in an increase in matching filtering output by a factor of 1.4–1.5 and finally resulting in a SNR gain of the same order.

Opis:

Streaming velocity depends on intensity and absorption of ultrasound in the media. In some cases, such as ultrasound scattered on blood cells at high frequencies, or the presence of ultrasound contrast agents, scattering affects the streaming speed. The velocities of acoustic streaming in a blood-mimicking starch suspension in water and Bracco BR14 contrast agent were measured. The source of the streaming was a plane 20MHz ultrasonic transducer. Velocity was estimated from the averaged Doppler spectrum. The single particle driving force was calculated as the integral of the momentum density tensor components. For different starch concentrations, the streaming velocity increased from 8.9 to 12.5mm/s. This corresponds to a constant 14% velocity increase for a 1 g/l increase in starch concentration. For BR14, the streaming velocity remained constant at 7.2mm/s and was independent of the microbubbles concentration. The velocity was less than in reference, within 0.5mm/s measurement error. Theoretical calculations showed a 16% increase in streaming velocity for 1 g/l starch concentration rise, very similar to the experimental results. The theory has also shown the ability to reduce the streaming velocity by low-density scatterers, as was experimentally proved using the BR14 contrast agent.

Opis:

Development trends (Research Trends) in scientific research on the methods of Multiple Criteria Decision Making (MCDM) and Multiple Criteria Decision Analysis (MCDA) in agriculture are analyzed. Established bibliometric techniques are applied. MCDA/MCDM methods are being very intensively developed in recent years, as evidenced by the number of scientific papers published annually in renowned scientific journals indexed in the Web of Science (WoS) database. In the years 1979-2015 a total of 1,355 scientific articles were collected in the database. The number of articles published annually increased rapidly after 2005. Besides, the annual number of citations of the publications is increasing. Research on MCDA/MCDM is conducted in many research areas. In the years 1984-2015 the Web of Science database accumulated 27 scientific publications on MCDA/MCDM in agriculture area. Therefore, it can be concluded that the MCDA/MCDM issues are currently not sufficiently analyzed in relation to agriculture. In the future this subject will probably be further developed, an increasing number of scientists will conduct research on the MCDA/MCDM and the annual number of articles published in the field will increase.

Opis:

This article presents a detailed history of the development of a particular immersion program to teach English to young Polish students. The program draws support from two organizations, the Kościuszko Foundation and the Polish Scouting Organization. Kościuszko Foundation is dedicated to strengthening the ties between the United States and Poland as well as to increase knowledge of Poland’s history and culture in the United States. The cooperation of these two organizations developed an experience of immersion in language and cultural exchange. Both the teachers and the students in this program benefited from the opportunity to engage in a number of different types of language activities and cultural events through a summer camp experience. This program is, of course, unique, but the elements of context, culture and immersion could be used in other programs to develop English skills and knowledge in the context American culture.

Opis:

Introduction. Mortality due to various causes, despite continuous efforts to improve the quality of medical services, is a serious problem for modern healthcare systems. Ischaemic heart disease and stroke are the cause of over 15 million deaths annually, and are therefore known as the world’s number one killer. Objective. The aim of this study is to characterise the missions and the most common reasons for dispatching Helicopter Emergency Medical Service (HEMS) crews, with special emphasis on the differences between urban and rural areas. Materials and method. The study was conducted using a retrospective analysis of HEMS missions, including flights to accidents and diseases carried out by HEMS crews in Poland from January 2014 – December 2018. The final analysis included 35,213 cases of HEMS missions. Results. The study group consisted mainly of male patients (66.40%), aged 50–64 (22.06%), mean age of the entire analysed group – 47.71 (SD: 25.96). The main reason for HEMS missions were strokes (21.63%). Analysis of patients’ clinical status revealed that the clinical status of patients treated in rural areas was more severe, which was indicated by the Glasgow Coma Scale – GCS (12.03 vs 12.35) and the Revised Trauma Scale – RTS (10.14 vs 10.60) scores. When assessed by the National Advisory Committee for Aeronautics (NACA) score, body injuries and fatal diseases were observed more often in patients in rural areas (NACA 7 6.12% vs 3.46%) (p<0.05). Conclusions. Multi-organ injuries, head traumas, sudden cardiac arrest, traumatic brain injuries, collapse and epilepsy, were more frequent reasons for HEMS missions in rural areas than in urban areas.

Opis:

Lactoferrin (LF) is a glycoprotein found in milk, neutrophil granules, secretions and selected organs of mammals. Lactoferrin exhibits antibacterial, antiviral, fungicidal, immunoregulatory and other functions. Although fish are devoid of this protein and its cell receptors, LF effect on the immune mechanisms of fish has been demonstrated. The objective of this study was to investigate the effect of bovine lactoferrin, applied in vitro, on the activity of head kidney and spleen leukocytes in three freshwater fish species: rainbow trout (Oncorhynchus mykiss), European eel (Anguilla anguilla) and weis catfish (Silurus glanis). The obtained results validate LF beneficial effect on the respiratory burst of phagocytes in rainbow trout and weis catfish despite the fact that the potential killing activity against Aeromonas hydrophila was not stimulated in any of the studied species. Bovine lactoferrin enhanced the proliferation of T-lymphocytes in rainbow trout and European eel, as well as of B-lymphocytes in rainbow trout.

Opis:

Freeze-dried elderberry and chokeberry were proposed as natural colorants for gluten-free wafers. In addition to colour, other physical and sensorial properties of wafer sheets were also evaluated. The elderberry powder was significantly darker (L* equal 37.61) than the chokeberry powder (L* equal 41.01), and it was characterized by a considerably lower a* value (4.21 in comparison with 12.32). These powdered fruits were added in the range from 0 to 5 %. A new indicator of wafer batter delamination was developed, which can also be proposed for other liquids. Significant and favourable changes were noted in the colour of both batter and wafers, with an increased content of fruits from 1 to 5%. Gluten-free wafers with a 5% addition of fruits were characterized by L*, a*, b* values, respectively, equalling 35.73, 6.05 and 3.24 for elderberry, and 39.74, 7.15 and 5.05 for chokeberry. Wafers with a 5% addition of chokeberry and elderberry, in comparison to control wafers, had significantly higher contents of minerals, including iron, potassium, calcium, magnesium and sodium. The freeze-dried elderberry powder, as compared to the chokeberry powder, was found to significantly increase the content of these minerals. In addition, the total flavonoids content was higher in the wafers containing elderberry. Freeze-dried chokeberry and elderberry can be proposed as natural colorants and valuable functional components for wafers.

The paper provides an analysis of the accuracy of a novel forest inventory method for calculating stand volume based on stratified sampling. The analysis included stand age as an efficient element used in the construction of the strata, as well as assessment results of various methods of sample allocation. This novel inventory method was compared with the methods based on simple random sampling or systematic sampling. The theory of all analysed methods for calculating stand volume is based on the mathematical statistics called a „representative sampling method”.

Introduction and objective. The nursing profession entails many negative factors and high risk of chronic diseases, including overweight and obesity. The aim of the study is to investigate the prevalence of overweight and obesity and health enhancing behaviours in Polish female nurses, and associations between overweight and 4 groups of such behaviours, age and shift work. Materials and method. The analysis covered data obtained through cross-sectional survey carried out in a group of 994 nurses with an average age of 43. The analysis covered answers about 29 health-enhancing behaviours divided into 4 categories (subscales): 1) nutrition, 2) physical activity, 3) sleep, rest and behaviours related to mental health, 4) preventive behaviours. They were analysed through the validated Positive Health Behaviours Scale for adults. The analysis also covered answers about avoiding drinking large amounts of alcohol in one go, not smoking, avoiding passive smoking, not abusing unprescribed drugs. Results. The prevalence of overweight and obesity was 44%. Of 29 health behaviours concerned with nutrition, physical activity, sleep, rest, and mental health, preventive behaviours, 3 were exhibited always or almost always by over a half of the nurses. Health behaviours were more common in nurses whose BMI was normal than in nurses with BMI ≥ 25.0. Age and low physical activity levels were related to overweight and obesity in nurses. Conclusions. The study revealed a high prevalence of overweight and obesity and many deficits in health behaviours. Obesity and health behaviour deficits pose risks to the health of nurses, limit their involvement in prevention and treatment of patient obesity and impact as health educators. It is essential to engage in actions for health promotion among nurses.

Celem opracowania jest określenie kierunków zmian w strukturze użytków rolnych w powiecie grójeckim w latach 1990-2010. Zmiany w powierzchni i strukturze użytków rolnych przeanalizowano na podstawie wyników Powszechnych Spisów Rolnych przeprowadzonych w 1996 oraz 2010 r. Analizy zmian w rozmieszczeniu sadów i gruntów ornych dokonano na podstawie mapy pokrycia terenu opracowanej przez Europejską Agencję Środowiska (Corine Land Cover).
The aim of the study is to determine changes in the structure of agricultural land in Grójec county and the direction of these changes in 1990-2010. The structure of agricultural land in Grójec county in the analysed period underwent heavy transformation. One factor that played a significant role in the this transformation was the change in economic conditions that followed Polish accession to the European Union. The accession made it necessary to adapt farms to operate in the new economic conditions. One of the conditions necessary to achieve good economic results and maintain profitability of production was specialisation. Even before Poland joined the EU, Grójec county was an area specialised in fruit picking, with orchards occupying 36% of the structure of agricultural land at the time. After Poland joined the EU, the area occupied by orchards started steadily growing, reaching 69% of all agricultural lands in the regions by 2010. The increase in the level of farm specialisation in fruit picking increased the area occupied by orchards, thus causing transformations in the structure of agricultural lands. As a result of the development of fruit picking, the area occupied by other types of agricultural production was limited. The area of arable lands decreased by 26%, meadows and pastures by 5%, while fallows and idle lands – by 2%. Some undeveloped lands not occupied by orchards has been dedicated to the cultivation of fruit trees and shrubs, or the construction of infrastructure related to fruit picking.

Optical and magnetic properties of ZnMnO films are discussed based on the results of cathodoluminescence, photoluminescence, and magneto-photoluminescence investigations. We show that photoluminescence/cathodoluminescence emissions are strongly quenched and become in-plane inhomogeneous in samples with increased Mn fractions. Strong polarization of photoluminescence is observed, even though excitonic lines do not shift and are not split at magnetic fields up to 6 T.

Introduction and Objective. The problem of occupational biohazards is very important, especially in the field of agriculture and in human and veterinary medicine. The aim of the study was to determine the potential sources of infection in veterinary professionals with selected zoonotic agents, including: Toxoplasma gondii, Giardia duodenalis, Leptospira spp., Cryptosporidium spp. and Coxiella burnetii. Materials and Method. A total of 50 air samples from barns, piggeries and veterinary surgeries were examined for the presence of Leptospira spp. and C. burnetii DNA. Serum samples of 86 pigs and 80 cows were tested for the presence of antibodies to Leptospira spp. and to phase I and II C. burnetii antigens. Serum of 70 cats were tested for the presence of antibodies to T. gondii and 65 samples of cat faeces for the presence of T. gondii oocysts. The presence of G. duodenalis and Cryptosporidium spp. were examined in 50 of dog faeces and 50 of bovine faeces samples. Results. DNA of Leptospira spp. was detected in 2 air samples from the piggeries (4%). C. burnetii DNA was not found in any sample. Anti-Leptospira spp. antibodies were detected in 51 (59.3%) of examined pigs. Neither anti-Leptospira spp. nor anti-C. burnetii antibodies were found among samples of bovine serum. Anti-T. gondii antibodies was found in 52 cat serum samples (74.3%). Among samples of cat faeces, no T. gondii oocysts were detected. In one sample of cattle stool (2%), G. duodenalis was detected and in another (2%) – Cryptosporidium spp. G. duodenalis was detected in 7 samples (14%) and Cryptosporidium spp. in 2 samples (2%) of dog faeces. Conclusions. The results of this study demonstrate the potential risk of infection with Leptospira spp. in veterinarians working with pigs. Veterinarians could be also be at risk of infection with T. gondii and G. duodenalis.

Opis:

The objective of this study was to evaluate the effect of HMB on selected indicators of immunity in calves. The experiment was performed on 14 calves aged 30±2 days, divided into two equal groups of control (group I) and experimental (group II) animals. The feed administered to experimental group calves was supplemented with HMB at 40 mg/kg BW, whereas control calves were administered standard farm-made feed without supplementation. Blood was sampled from the jugular vein immediately before the experiment (day 0) and on experimental days 15, 30 and 60 to determine the following parameters of immunity: proliferative response of LPS- and ConA-stimulated lymphocytes (MTT), respiratory burst activity (RBA) and potential killing activity (PKA) of phagocytes. The results revealed a significant increase in RBA and MTT values in calves administered HMB in comparison with the control group throughout the experiment. In the group of animals receiving HMB, an increase in PKA values was noted only on day 30.
