Opis:
Specifically, it was tested whether the presence of O2 in the headspace modified the sequence and preference of electron acceptor use under hypoxic conditions after prolonged drought in arable soils. This laboratory study was conducted in order to examine the use of electron acceptors: oxygen (O2), nitrate (NO3¯) and nitrous oxide (N2O), during aerobic and anaerobic respiration (denitrification). Agricultural soils (Typic Dystrudepts) classified as sandy, silty and loamy soils from arable top soils (0-30 cm) were used in the study. The change of oxidation states of different chemical species in the soil affected the use of electron acceptors during denitrification. The use of O2, NO3¯ and net N2O use was gradual and differed greatly among the soils. Furthermore, microorganisms were shown to be able to use all three investigated electron acceptors simultaneously, but with clearly visible preferences. The rate of electron acceptor use per day differentiated the investigated soils into a few different groups. Overall, the results of this study indicated that N2O was a more preferable electron acceptor than NO3¯ when O2 was present in the headspace for the most investigated soils. Moreover, a correlation existed between the final electron acceptor use and particle-size distribution and the native organic C content (Corg). The rate of electron acceptor use per day calculated for O2, NO3¯ and N2O may provide very important information for distinguishing the preference of electron acceptor use during aerobic and nitrate respiration in agroecosystems under hypoxic conditions after prolonged drought for different kinds of electron acceptor.

Opis:
There are many methods for detection of Cryptosporidium oocysts. Most of them (more than 20) enable the microscopic detection of Cryptosporidium oocysts in faecal smears. Such a great variability of diagnostic methods may lead to confusion as far as the choice of an appropriate technique by a given laboratory is concerned. This study evaluated the diagnostic usefulness of Cryptosporidium oocysts and coproantigen detection methods in the diagnosis of cryptosporidiosis in human (266 stool specimen) and animals (205 from cattle, 160 from sheep, 30 from horses, 80 from cats, 227 from dogs and 11 from wild animals). The total number of human and animal stool specimens processed was 266 and 713, respectively. In this study the usefulness of several diagnostic methods was compared. The following techniques were taken into account: wet mounts, hematoxylin staining, four different specific methods (modified Zeihl-Neelsen, Kinyoun's, safraninmethylene blue, as well as carbol-methyl violet and tartrazyne) and commercially available kit based on enzyme-linked immunoassay (ProspecT(r) Cryptosporidium Microplate Assay). The final number of positive specimens was 123. Out of them 77 were positive in all specific methods. The oocysts found in stool specimens were measured. Humans were infected with C. parvum and animals with C. parvum, C. andersoni or C. felis. The statistical analysis has shown that EIA test was a better than microscopy method for identification of Cryptosporidium in faecal samples in human and wild animal. Sensitivity and specificity are important factors for the choice of a proper diagnostic method for Cryptosporidium detection, however other factors such as cost, simplicity and ease of interpretation of results are also important considerations.

Opis:
Ascariasis is the most common soil-transmitted helminth infection in the world. The objective of this study was to analyze the clinical symptoms and selected hematological indices of ascariasis in hospitalized children from the northeastern region of Poland. Patients in the Pediatric Ward hospitalized in the Regional Hospital in Dąbrowa Białostocka in the period of 2005–2007 were included in this retrospective study. The intestinal stage of ascariasis was diagnosed on the basis of positive coprological survey performed using the decantation technique. A total of 938 patients were included in the study, 1801 stool samples were evaluated, and A. lumbricoides-positive tests were obtained from 252 children. Ascaris-positive young children (3 yrs) accounted for 3.0% of all hospitalized children, Ascarispositive preschool-aged children (4–7 yrs) accounted for 8.1% and school-aged children (8–18 yrs) for 15.8%. Seasonal patterns were observed in the prevalence of A. lumbricoides (maximum in August–December). There was no relationship between BMI z-score, hemoglobin levels and prevalence of infection with Ascaris lumbricoides. Significant predictors of intestinal stage ascariasis in a multivariate logistic regression model were: abdominal pain as a reason for hospital admission (OR–2.19; 95%CI 1.62–2.95; p<0.001) and age from 4 to 7 years (OR–2.0; 95%CI 1.41–2.80; p<0.001). The prevalence rate of ascariasis was not higher in the group of patients with atopic diseases (bronchial asthma, allergic rhinitis, atopic dermatitis) and co-existing ascariasis did not affect the eosinophil counts in the peripheral blood. Ascariasis is still a current pediatric clinical problem characterized by non-specific clinical manifestations, which should be taken into consideration in the differential diagnosis of children’s diseases.

Opis:
In contrast to terrestrial animals, fish can ingest minerals from food or directly from water. Although micro- and macro-elements are needed in small quantities, they play a key role in many metabolic processes. Trace mineral and macromineral deficiencies may go unnoticed due to an absence of clear clinical symptoms in fish. Absorption processes are determined by various factors, mostly mineral concentrations in water but also other water parameters. The required dietary supplementation of macronutrients and micronutrients is very difficult to determine, and the amount of nutrients absorbed by fish from water is equally difficult to measure. Interactions between elements should also be taken into consideration. Many authors emphasize that phosphates may reduce the absorption of most micronutrients. Also, the current parameters of the water can affect the bioavailability. Some elements such as calcium, chlorine and sodium can be absorbed from ambient water in a quantity sufficient to meet the demand for this element. Other elements, however, require supplementation in a diet. For example, studies indicate the need for supplementation of phosphorus, zinc, copper and manganese. Most research concentrates on feedstuff as a source of micro- and macronutrients. Meanwhile, information concerning bioavailability of minerals directly from water is scarce. The aim of this study was to analyse literature from a different perspective, and concentrate on water as a source of minerals in fish nutrition. Measurements of water parameters such as temperature, pH, nitrate and nitrite levels and the amount of dissolved oxygen are a regular component of environmental control in fish farming. Determination of micro- and macro-element levels, however, remains uncommon in aquaculture. Measurements of these parameters could suggest which elements need to be supplemented and which are found in water in amounts that satisfy the needs of the fish.

Opis:
The aim of this study was to verify first-order kinetic reaction rate model performance in predicting of leaching of atrazine and inorganic compounds (K+1, Fe+3, Mg+2, Mn+2, NH4 +, NO3 - and PO4 -3) from tilled and orchard silty loam soils. This model provided an excellent fit to the experimental concentration changes of the compounds vs. time data during leaching. Calculated values of the first-order reaction rate constants for the changes of all chemicals were from 3.8 to 19.0 times higher in orchard than in tilled soil. Higher first-order reaction constants for orchard than tilled soil correspond with both higher total porosity and contribution of biological pores in the former. The first order reaction constants for the leaching of chemical compounds enables prediction of the actual compound concentration and the interactions between compound and soil as affected by management system. The study demonstrates the effectiveness of simultaneous chemical and physical analyses as a tool for the understanding of leaching in variously managed soils.

Opis:
X-ray reflectometry and spectroscopic ellipsometry methods were applied for determination of physical properties of gold nonolayers. The nanolayers were prepared by sputtering of gold on different substrates: borosilicate glass, polished crystalline quartz and crystalline silicon. With X-ray reflectometry technique roughness of the substrates and density, thickness and roughness of gold layers were determined. The results showed decrease in density of the gold layers due to their nanometer thickness and that roughness of the underlayer affects roughness of the gold layer. In addition, thicknesses of the gold layers measured with spectroscopic ellipsometry turned out to be in agreement, within the experimental uncertainty, with results of the X-ray reflectometry method.

Opis:
Giardia duodenalis (syn. G. intestinalis, G. lamblia) is a cosmopolitan flagellate organism belonging to the most common intestinal protozoan parasites of humans and animals. Great genetic heterogeneity has been found within G. duodenalis, where only genotypes representing assemblages A and B have zoonotic potential. Fecal samples (447 specimens) obtained from 232 humans in West-central region of Poland were examined by microscopy and PCR. The total prevalence of Giardia in humans was 1.3%. DNA was extracted from three positive fecal samples and PCR products were obtained after amplification using the β-giardin primers G7 and G759. Sequence and phylogenetic analyses showed that G. duodenalis isolates from humans belonged to A and B genotypes. Moreover, three subgenotypes, including a cosmopolitan subgenotype A2 and two new subgenotypes A and B were detected.

Opis:
In this study total of 266 fecal samples from 242 animals belonging to 113 species kept in the Poznan Zoological Garden were examined for Giardia. The cysts of Giardia were found only in five samples of feces collected from a giant toad (Bufo marinus), tamandua (Tamandua tetradactyla) and three individuals of cactus mouse (Peromyscus eremicus). Fragments of β-giardin (bg), triose phosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes were successfully amplified only from the Giardia isolate obtained from the tamandua. Sequence and phylogenetic analyses showed that the Giardia isolate from the tamandua belonged to the B assemblage and showed homologies of 99% to 100% at bg, gdh and tpi loci of the same markers of parasites isolated from humans and animals in various parts of the world. This is the first molecular characterization of G. duodenalis from tamandua.
