The second and third fractions of the ejaculate were collected separately by digital manipulation. Total antioxidant capacity (TAC) and the concentrations of SH-groups in sperm and prostatic fluid were determined spectrophotometrically, the concentrations of bityrosine and formylkynurenine were determined using spectrofluorimetric methods. The mean values of TAC in spermatozoa and prostatic fluid were significantly lower (p<0.05), whereas the mean contents of biotyrosine and formylkinurenine were significantly higher (p<0.05) in BPH dogs compared to control dogs. There was no statistically significant difference in the content of SH group between dogs with BPH and control dogs (p>0.05). In conclusion, the results indicate that BPH in dogs is associated with reduced total antioxidant capacity and increased protein oxidation in the prostatic fluid and spermatozoa, and suggest the importance of oxidative stress in the pathogenesis of this condition.

Research to determine the correlation between the health status of female dogs and bacterial flora of the genital tract has been ongoing for years, but the results obtained by different authors are often contradictory, and do not always concern breeding bitches. Our study identified the most common aerobic bacteria in the genital tract of numerous breeding bitches population. A total of 275 breeding dogs in anestrous phase of the estrous cycle were included in this study. 198 were qualified to the first group with no genital tract infections and no reproductive disorders. 68 bitches were qualified to the second group with complications such as: infertility, abortion, foetus resorptions and newborn mortality. The type of bacterial isolates was almost the same in the healthy bitches and the group with fertility problems. The most common bacteria obtained from the vaginal tract of the tested dogs were Streptococcus spp., Staphylococcus spp., Mycoplasma canis and Escherichia coli. There were no significant differences in bacterial prevalence in the group with reproductive problems versus healthy dogs; however, we found a statistically significant difference between both groups when the numbers of bacterial strains were compared. The number of one-strain bitches was statistically higher in the problematic group than in the non-problematic one. Bacterial culturing of vaginal swab specimens from breeding bitches without clinical signs of genital disease is of little value. Furthermore, it should always be preceded by an examination (clinical, cytological or vaginoscopy etc.). The request or requirement to perform vaginal cultures that is made by some breeders, while common, is not diagnostic for any pathologic condition and the results of these cultures should never be used to determine if antibiotic therapy is indicated.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"26 4","pages":"733-739"},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138805818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The swine industry faces a significant economic and epizootic threat; thus, finding a reliable, quick, and practical way to detect it is essential. In this investigation, recombinant PPV VP2 protein was expressed in the Escherichia coli ( E. coli) expression systems. As shown by electron microscopy (TEM), Western blot, and hemagglutination (HA) assays, the recombinant VP2 protein was successfully assembled into virus-like particles (VLPs) after being expressed and purified. These VLPs had a structure that was similar to that of real PPV viruses and also exhibited HA activity. These VLPs induced high levels of PPV-specific antibody titers in mice after immunization, indicating that the VLPs may be beneficial as potential candidate antigens. VLPs were used as the coating antigens for the VLP ELISA, and the PPV VLPs-based ELISA displayed a high sensitivity (99%), specificity (93.0%) and agreement rate (98.3%) compared to HI assay, and the agreement rate of this ELISA was 97.5% compared to a commercial ELISA kit. Within a plate, the coefficient of variation (CV) was 10%, and between ELISA plates, the CV was 15%. According to a cross-reactivity assay, the technique was PPV-specific in contrast to other viral illness sera. The PPV VLP indirect-ELISA test for PPV detection in pigs with an inactivated vaccine showed that the PPV-positive rate varied among different sample sources from 88.2 to 89.6%.

The Listeria concentration in carrot juice samples decreased from average of 4.94 on day 5 to 3.24 log CFU/mL on day 10, and on day 15 achieved <0.01 log CFU/mL.

Results showed that ERT inhibited S. pseudintermedius growth regardless of harboring the mecA gene, and APS increased the inhibitory effects of ERT against S. pseudintermedius, S. schleiferi, and S. aureus in vitro. Moreover, combined ERT and APS decreased the prevalence of staphylococci on canine skin lesions at the genus level.
