    Opis:
    Investigation into herd-level seroprevalence of caprine herpesvirus type 1 (CpHV-1) and bluetongue virus (BTV) was conducted in 2007 in Poland. It involved the entire population of goats covered by a milk recording program in 2007, which included 49 goat herds. The number of goats examined in each herd was determined statistically in order to detect the presence of at least one seropositive animal in a herd with a 95% probability and simple random method of sampling was applied. No antibodies to CpHV-1 or BTV were detected. Further calculations were carried out to determine the herd-level true seroprevalence, taking into account sensitivity and specificity of the test as well as several other factors. It can be concluded that till the middle of 2007 population of Polish goats covered by the milk recording program remained negative with respect to CpHV-1 and BTV.

    Opis:
    The observational study was carried out in a population of Polish breeding goats in 2007 to determine the prevalence of fetal loss and identify risk factors contributing to its occurrence. The multivariate model allowing to predict the risk of the occurrence of fetal loss in a herd in a study population was developed. Data on the occurrence of fetal loss, as well as of 28 hypothesized risk factors were collected from goat owners using standardized questionnaire during face-to-face reviews on farms. Moreover, data on the herd-level seroprevalence of four abortifacient infections – Chlamydophila abortus, Leptospira spp., BVDV-1 and Neospora caninum – were included in the final analysis. Fetal loss was reported as occurring often in 12 of 49 goat herds (24.5%). The relationship between the hypothesized risk factors and the occurrence of fetal loss was verified in the multivariate logistic regression (α=0.05). Final analysis yielded four risk factors: regular veterinary supervision at least twice a year (OR 0.188; CI 95% 0.054 – 0.656), frequent occurrence of injuries and fractures (OR 3.172; CI 95% 1.081 – 9.310), frequent occurrence of respiratory signs in adult goats (OR 4.848; CI 95% 1.353 – 17.377) and presence of antibodies to C. abortus in a herd (OR 58.116; CI 95% 1.369 – 2466.438). The accuracy of the multivariate model was analyzed using receiver operating characteristic (ROC) curve technique. Area under the curve was 0.895 (CI 95% 0.801-0.981). For optimal cut-off value of 0.20-0.35 the multivariate model had sensitivity of 75.00% and specificity of 89.19% in predicting fetal loss in a herd.

    Opis:
    An epidemiological study was carried out to determine the herd prevalence of Chlamydophila abortus and Coxiella burnetii antibodies in goats covered by a milk recording program in Poland. The survey took place in 2007 and 48 herds located in different parts of the country were involved. A representative sample from each herd was taken by a simple random sampling allowing to detect seropositivity of a herd on a 95% level of confidence. In total 918 goats were tested for specific antibodies against both germs with the use of enzyme-linked immunosorbent assays. In addition, history of reproductive failures was recorded in these herds. The survey revealed that the herd prevalence of C. abortus was 4.2% (2 herds) while no C. burnetii antibodies were found. Abortions were reported to be a problem in 80% of herds while repeating estrus was encountered in 46% of herds. Reproductive failure concerned two seropositive herds as well. Since the germ is present in the population, it has to be taken into consideration in diagnostic process. Nevertheless, the results of the present study indicate that C. abortus infection occurs infrequently in Polish goats. As no antibodies against C. burnetii were detected in the screened sample the risk of goat-to-human transmission of both bacteria in Poland seems to be very low.

    Opis:
    Diagnostic performance of ID Screen® MVV-CAEV Indirect Screening ELISA in identifying goats infected with small ruminant lentiviruses (SRLV) was evaluated. In total 299 serum samples from the collection of the Laboratory of Veterinary Epidemiology and Economics - 109 truly positive and 190 truly negative - were used. To be enrolled in the study a serum sample had to come from at least 2 year-old goat which had reacted identically in two serological surveys preceding sample collection and was kept in a herd of stable serological status confirmed at least twice during preceding 5 years. Moreover, in seropositive herds at least 20% of goats had to be serologically positive at the moment when the serum sample was collected for the study. The test proved to have high accuracy. Area under curve was 98.8% (95% CI: 97.5%, 100%). Diagnostic performance of the test was almost identical (Youlden’s index of 90%, sensitivity >90% and specificity >95%) within a fairly wide range of cut-off values - between 20% and 60%. At manufacturer’s cut-off of 50% sensitivity and specificity were 91.7% (95% CI: 85.0%, 95.6%) and 98.9% (95% CI: 96.2%, 99.7%), respectively. For this cut-off positive likelihood ratio was 87 (95% CI: 22, 346) and negative likelihood ratio was 0.08 (95% CI: 0.04, 0.16). In conclusion, the results of this study indicate that ID Screen® MVV-CAEV Indirect Screening ELISA is a highly accurate diagnostic test for SRLV infection.

    Opis:
    Epidemiological studies on caseous lymphadenitis were carried out in Poland in 1996 and 2002 among goat herds covered by a milk recording program. Between-herd seroprevalence was 13.2% in 1996 and increased to 62.5% in 2002. The average size of seropositive herds was statistically significantly higher than that of seronegative ones, however there was no statistically significant difference in the age between the herds. A statistically significant prevalence ratio (PR) was identified and relevant attributable risk for exposed animals (ARexp) was calculated for the following risk factors: presence of seropositive males in a herd (PR=8.350; ARexp=0.651), presence of superficial abscesses in animals (PR=6.142; ARexp=0.620), presence of respiratory signs (PR=2.900; ARexp=0.393), presence of animals in poor condition in a herd (PR=2.774; ARexp=0.390) and occurrence of reproductive failures in a herd (PR=1.798; ARexp=0.230). Purchase of animals from abroad, mastitis and husbandry conditions (housing system, grazing system, hygienic conditions) were not shown to be statistically significant risk factors.

    Opis:
    Background: Hucul horses are the unique, genetically distinct breed of Carpathian Mountains. Even though they are recognized as primitive breed, many morphological differences between them and other primitive horses have been reported. Neither hematological nor blood biochemical studies in this breed have been conducted so far. Objectives: The aim of this study was to establish the reference intervals for basic hematological and selected biochemical variables and to compare them with other breeds. Material and Methods: Blood samples were collected from 168 Hucul horses and the analyses were performed using routine methods. Mainly nonparametric method was used to establish reference intervals. Results: The following reference intervals have been established (rounded to two significant digits): RBC: 7.0-13x1012/l; HGB: 106.1-195.8 g/l; HCT: 0.3-0.6 l/l; MCV: 35-50 fl; MCH 11.9-17.1 pg; MCHC: 31.9-34.8 g/dl; WBC: 7.5-22x109/l, bands: 0-0.5x109/l; segmented neutrophils: 3.3-10x109/l; eosinophils: 0-1.1x109/l; basophils: 0-0.3x109/l; lymphocytes: 1.9-12x109/l; monocytes: 0-0.2x109/l; PLT 95-350x109/l; MPV 5.2-7.0; ALP: 98-425 U/l; AST: 220-470 U/l; GGT: 9.1-31 U/l; total bilirubin: 6.5-29 μmol/l; CPK: 120-640 U/l; triglycerides: 0.1-0.9 mmol/l; urea: 3.8-11 mmol/l; creatinine: 44 -140 μmol/l; serum amyloid A: 130-5200 μg/l. Conclusions: Hematological and biochemical variables in Hucul horses were closer to hot-blooded then to cold-blooded and primitive horses or wild equidae. The reference intervals presented in this study pose clinically useful tool for evaluation of blood check-up in Hucul horses.

    Opis:
    Our studies focus on test structures for photovoltaic applications based on zinc oxide nanorods grown using a low-temperature hydrothermal method on a p-type silicon substrate. The nanorods were covered with silver nanoparticles of two diameters – 20–30 nm and 50–60 nm – using a sputtering method. Scanning electron microscopy (SEM) micrographs showed that the deposited nanoparticles had the same diameters. The densities of the nanorods were obtained by means of atomic force microscope (AFM) images. SEM images and Raman spectroscopy confirmed the hexagonal wurtzite structure of the nanorods. Photoluminescence measurements proved the good quality of the samples. Afterwards an atomic layer deposition (ALD) method was used to grow ZnO:Al (AZO) layer on top of the nanorods as a transparent electrode and ohmic Au contacts were deposited onto the silicon substrate. For the solar cells prepared in that manner the current-voltage (I-V) characteristics before and after the illumination were measured and their basic performance parameters were determined. It was found that the spectral characteristics of a quantum efficiency exhibit an increase for short wavelengths and this behavior has been linked with the plasmonic effect.
