Control basic principle regarding retardation sign in titration involving double protein by means of chips transferring response border electrophoresis.
Our study confirms the role of CPNV in TVP pathogenesis and it seems that preservation of the proventriculi in the early stages of the disease, when the lesions are more pronounced, should result in a greater probability of CPNV detection.The study aimed to determine the content of selenium (Se), zinc (Zn), copper (Cu) and cadmium (Cd) in the liver of predominantly plant-eating omnivore wild boar (Sus scrofa), predominantly meat-eating omnivore red fox (Vulpes vulpes) and herbivore red deer (Cervus elaphus), from North-Eastern Poland (Warmia and Mazury), in order to verify the distribution of these elements in the trophic pyramid. Furthermore, the study was used to assess the risk of eating venison. Samples were analyzed using atomic absorption spectrophotometry. The average concentration of Se was 3.9 (p⟨0.001) and 1.8-fold higher (p0.001) in the wild boar and red fox, respectively, in comparison to the red deer, and 2.1-fold higher in the wild boar comparing to the red fox (p⟨0.001). There was no difference in the average concentration of Zn. The average concentration of Cu was 9.3. Concentration of this element was 5.4-fold higher in red deer in comparison to red fox (p⟨0.001) and 9,34-fold higher than in wild boar (p⟨0.001). The average concentration of Cd was 1.9-fold higher in wild boar in comparison to the red fox (p⟨0.029). Correlation between Cu and Cd concentrations was also observed in the case of the red deer and red fox, while no such correlations were observed between the tested elements in the wild boar. In conclusion, the liver concentrations of these heavy metals in selected wild animas species from the hunting areas of Warmia and Mazury, do not exceed standard safe values for consumers. Moreover, the wild red deer population in North-Eastern Poland is significantly Se deficient.Three-dimensional (3D) models created with computers and educational applications designed using such models are used in the medical field every day. However, there is a lack of macroscopic demonstration applications built with digital 3D models in the field of veterinary pathology. The aim is to build a fully interactive 3D educational web-based augmented reality application, to demonstrate macroscopic lesions in kidneys for educational purposes. We used open source and free software for all 3D modelling, Augmented Reality and website building. Sixteen 3D kidney pathology models were created. Kidney models modelled in 3D and published as WebAR are as follows normal kidney, unilateral neurogenic shutdown with atrophy, hydronephrosis, hypercalcemia of malignancy tubular nephrosis, interstitial corticomedullary nephritis, renal infarct, multifocal petechial hemorrhages, polycystic kidneys, renal masses, multifocal nephritis, pigmentary nephrosis, papillary necrosis, glucose-related rapid autolysis (pulpy kidney), pyelonephritis, renomegaly and kidney stones. With the workflow shown here, it has been presented as a feasible model application for human pathology and presented to educators, researchers and developers who have 3D models and AR in their field of interest. To the best of the authors' knowledge, this is the first study on Web-Augmented Reality application for veterinary pathology education.The aim of the study was to determine the effects of feed addition of LAVIPAN PL5 probiotic preparation containing compositions of microencapsulated lactic acid bacteria (Leuconostoc mesenteroides, Lactobacillus casei, Lactobacillus plantarum, Pediococcus pentosaceus) on production parameters and post-vaccinal immune response in pigs under field condition. The study was performed on 400 pigs in total and 60 pigs from this group were used to evaluate the effect of the product tested on the post-vaccinal response. The animals were divided into two groups control group, fed without additive of LAVIPAN PL5 and the study group, receiving LAVIPAN PL5 at doses recommended by manufacturer from weaning to the end of fattening. The following parameters were recorded main production parameters, including weight gains, fattening time (slaughter age) and animal health status during the study (mortality), and specific humoral post-vaccinal response after vaccination against swine erysipelas. The results indicate that the application of LAVIPAN PL5 had positive influence on the animals` productivity and did not significantly affect the post-vaccinal antibody levels and the development and maintenance of the post-vaccinal response, albeit the levels of antibodies were slightly higher in the animal receiving the test preparation. The higher average daily weight gains (by over 3%) which resulted in a 2 kg higher average weight at slaughter and a reduction of the fattening period by 5 days, undoubtedly contributed to significant economic benefits.Several pre-analytical factors may influence the accurate measurements of testosterone (T) and therefore, these factors must be a significant concern. This study aimed to examine the effects of 1) time of sample collection, 2) delay to centrifugation, 3) sample matrix types, and 4) device and duration of sample storage on the T concentrations. Blood samples were collected from 34 bucks of Kacang goats. For testing the effect of collection time, 12 pairs of morning and afternoon samples were collected. For testing the effect of delayed centrifugation, 24 samples were subjected to treatments (i) centrifuged ⟨1 hour after collection (control group), (ii) centrifuged 6, 12, and 24 hours after collection (test groups). For testing the different sample matrix types, 10 samples were processed as serum and plasma. For testing the effect of sample storage device and duration, 60 samples were subjected to treatments i) frozen at -20OC (control group), ii) stored in a cooler box, a styrofoam box, and a thermos-flask for two, four, and six days (test groups). T concentrations were measured using a validated testosterone ELISA kit. Concentrations of plasma testosterone (pT) from morning samples were significantly higher compared to afternoon samples (p⟨0.05). Delayed centrifugation for up to 24 h decreased significantly on pT concentrations (p⟨0.05). The concentrations of T from serum and plasma did not differ and showed a strong correlation (r=0.981). Storage device and duration affected the T concentrations compared to frozen samples (p⟨0.05) which T concentrations were stable for up to 4 days in a styrofoam box and a thermos-flask and up to 6 days in a cooler box. In conclusion, the measurement accuracy and stability of T concentrations in goats are affected by collection time, delay to centrifugation, and device and duration of storage.Diarrhea caused by parasitic agents is common in neonatal calves and leads to significant economic losses in cattle farms worldwide. Cryptosporidium spp. is one of the most frequently detected parasitic agents causing diarrhea in neonatal calves. The aim of this study was to investigate the presence of Cryptosporidium spp. on a dairy farm which a has major diarrhea problem. Samples were collected from calves, cows, drinking bowls, and two different artesian water sources, as well as from the environment. All fecal samples were investigated using Kinyoun acid-fast stained slides and real-time PCR targeting the Cryptosporidium spp. COWP gene. In addition, species identification was performed by nested PCR targeting the Cryptosporidium spp. COWP gene and sequencing. Cryptosporidium spp. was detected in 11 calves (30.55%; 11/36) by real-time PCR and the cows were negative. Among real-time PCR positive samples, only five were also found positive by microscopy. Moreover, Cryptosporidium spp. was found in one of the two artesian water sources and five environmental samples by real-time PCR. Among these positive samples, eight were sequenced. According to the RFLP pattern, BLAST and, phylogenetic analyses, all sequenced samples were Cryptosporidium parvum. These findings show the importance of C. parvum as a cause of calf diarrhea on dairy farms.The aim of this study was to evaluate the efficacy of the Ovsynch protocol in the treatment of post-service subestrus in individual dairy cows compared to a single administration of PGF2α. The study was performed on 517 Polish Friesian Holstein cows with post-service anestrus over four years in 3 dairy herds under a herd health program. Cows (n=240) diagnosed ultrasonographically as non-pregnant and with a mature corpus were treated with a single PGF2α administration and inseminated at detected estrus. Cows without corpus (n=277) were treated with the Ovsynch protocol. The estrus detection rate after PGF2α administration, percentages of cows pregnant after the treatment and at day 260, intervals from parturition to treatment and from treatment to conception and pregnancy loss rates were calculated. The overall percentage of cows pregnant after treatment did not differ between animals treated with the Ovsynch protocol and with PGF2α (38.9% vs. 42.5%; p>0.05). In herd A the percentage of cows pregnant after treatment was significantly lower (p⟨0.05) for the Ovsynch group than for the PGF2α group (30.2% vs. 61.2%). In contrast, in herd C the percentage of cows pregnant after treatment was significantly higher (p⟨0.05) in the Ovsych group than in the PGF2α group (39.6% vs. BV6 28.8%). The overall estrus detection rate after administration of PGF2α was 59.6%. However, it was significantly lower (p⟨0.05) in herd C (44.7%) than in herds A (79.6%) and B (76.3%). The overall pregnancy loss rate ranged from 5.1% to 13.3% and did not differ significantly between herds and treatment groups (p>0.05). In conclusion, Ovsynch protocol can be a useful alternative for treatment of post-service suboestrus in individual cows in dairy herds with insufficient oestrus detection.The aim of the study was to determine the utility of maximum eye temperature measured by infrared thermography (IRT) as a stress indicator compared with plasma cortisol concentration in Thoroughbred and Arabian racehorses. The study included thirty racehorses undergoing standard training for racing. Measurements of maximum eye temperature and blood collection for plasma cortisol concentration were carried out before training (BT), and within 5 (5AT) and 120 minutes (120AT) after the end of the each training session in three repetitions, with a monthly interval. Both parameters were elevated at 5AT compared to BT (p⟨0.001). Compared to BT, at 120AT the maximum eye temperature remained elevated (p⟨0.001) and plasma cortisol concentration decreased (p⟨0.001). The study indicated significant weak correlations (r=0.220; p⟨0.001) between both measurements at all time points. The results support the use of IRT technique to monitor the response of horses to stress, potentially improving animal management and welfare.Reticuloendotheliosis virus (REV) is an avian oncogenic retrovirus that causes atrophy of immune organs, such as the spleen, thymus, and bursa of Fabricius, leading to severe immunosuppression. However, there is limited information describing the genes or microRNAs (miRNAs) that play a role in replicating REV-spleen necrosis virus (SNV). Our previous miRNA and RNA sequencing data showed that the expression of gga-miR-222b-5p was significantly upregulated in REV-SNV-infected chicken spleens of 7, 14, and 21 dpi compared to non-infected chicken spleens, but mitogen-activated protein kinase 10 (MAPK10), which is related to innate immunity, had the opposite expression pattern. To understand chicken cellular miRNA function in the virus-host interactions during REV infection, we used quantitative reverse transcription PCR (qRT-PCR) to determine whether the expression of gga-miR-222b-5p and MAPK10 in the spleen of specific-pathogen-free chickens at 28, 35, and 42 dpi was consistent with the first 3 time points, and dual-luciferase reporter assay was used to determine the targeting relationship between gga-miR-222b-5p and MAPK10.
