Escherichia coli is the most important bacterial agent of NCD. Although vaccination and antibiotic treatment are common in NCD, the high antigenic diversity of E. coli and the increase in antibiotic resistance cause difficulties in the control. The study aimed to investigate the rate of E. coli in calf diarrhea, isolate an agent of the NCD E. coli strain, determine antimicrobial resistance, and find out about some surface antigens. Fecal samples (n=115) were analyzed to isolate pathogenic E. coli strains with nine mixed infections; sixty-one strains isolate from fifty diarrhoeic calves. Among the isolates from diseased animals, 22 K99+STa+F41, 3 K99+STa, 3 strains F41, 2 strains Stx1, one strain K99, one strain eae, and one strain Stx2+eae were detected. 27 strains of F17- associated fimbriae have been identified. 17 strains F17a, 6 strains F111, 3 strains F17c, one strain carrying the F17a and F17c gene regions, whereas subfamily typing of one strain could not be performed. Serotypes were determined by molecular and serological methods: 32/61 (52.5%) isolates were O101 and 2/61 (3.3%) isolates were O9 serotypes. But 27 strain serotypes could not be detected. The antibiotic resistance profiles of the isolates were determined by the disc diffusion method. The resistance rates to antibiotics were trimethoprim- sulphamethoxazole 91.7%, ampicillin 86.7%, enrofloxacin 86.7%, gentamicin 45%, tobramycin 41.7%, cefotaxime 3.3%, and ceftazidime 1.7%. Due to increasing antibiotic resistance, prophylaxis is gaining importance. In further research, E. coli surface antigenic structures should be examined in detail, and it should form the basis for vaccine and hyperimmunization studies to be developed.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"26 3","pages":"335-341"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41168275","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 study was carried out between August and November of 2020. The samples of horse feces were collected from 50 different stables in the area of Lower Silesia, Poland. A total of 286 individuals from various breeds were examined. Detailed analysis revealed that the mean age of infected horses was significantly lower than in uninfected horses. The mean time since the last deworming procedure was almost twice as low in uninfected horses than in infected ones. Additionally, the deworming agent affects the prevalence of infection. The analysis was also performed for the same factors in reference to quantitative data. The mean EPG was four-fold higher in juvenile horses than in adults and three-fold higher when the horses were dewormed with the use of fenbendazole instead of ivermectin or ivermectin with praziquantel combined.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"26 3","pages":"401-407"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41125508","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}

Merozoite surface antigens (MSAs) have been identified as efficient immunogens in Babesia-infected animals. MSAs play a key role in the invasion process and have been proposed as potential targets for vaccine development. Epitope-based vaccines offer several advantages over whole protein vaccines as the immunogenic proteins are small and can induce both Th1 and Th2 immune responses, which are desirable for protection. However, the MSA, particularly gp45, is polymorphic in Babesia bigemina, posing a challenge to vaccine development. The purpose of this study was to develop a recombinant gpME (gp45-multi-epitope) for a vaccine against Babesia bigemina. B-cell, T-cell, and HLA epitope predictions were used to synthesize the gpME sequence from the consensus sequence of gp45. The gpME sequence was synthesized and cloned in the pET28α vector through the commercial biotechnology company to get pET28-gpME. The plasmid cloned with the gpME sequence comprising 1068 bp was expressed in a bacterial expression system. A band of 39 kDa of rec-gpME was obtained via SDS-PAGE and Western blotting. Rec-gpME @200ng was injected in calves 3 times at 2 weeks interval. The humoral response was evaluated through the indirect ELISA method. The ELISA with rec-gp45 protein showed a significant value of optical density. The recombinant protein containing multiple epitopes from the MSA gp45 may represent a promising candidate for a vaccine against Babesia bigemina.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"26 3","pages":"409-418"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41160745","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 study included data from a total of 17659 lambs and 12263 ewes raised in 30 herds between the years 2011 and 2016 as part of the National Sheep and Goat Improvement Project. The average birth weight of the lambs was determined as 3.73±0.05 kg, the average 45th day live weight was 18.43±0.58 kg, the average weaning (average 91.8 days) weight was 31.83±0.24 kg, and the average daily live weight gain until weaning was 289.1±3.91 g. The average survival rate of lambs at weaning was calculated to be 95.67% ± 1.15. The effects of the factors herd, birth year, birth type, birth season and sex were found significant for all traits (p<0.01). It was established that the mortality rate in lambs in large herds was higher during 6 years in which the project was carried out. Due to the high twinning rate in large herds, the number of lambs per worker is increased, and as a result, they cannot be adequately cared for. For this reason, large farms may be encouraged to increase workmanship services in addition to being provided with protective health practices for lambs throughout the birth period. On the other hand, it was determined that the twinning rate was low in small farms. On farms with fewer sheep populations, it may be advised to flush or administer exogenous hormone treatments to ewes in order to increase fertility and help them bear twins.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"26 3","pages":"473-481"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41180810","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}

Due to the predominant bacterial etiology otitis is usually treated with antibiotics. However, non-prudent use of antibiotics promotes the emergence of antibiotic-resistant bacteria thus compromising the therapy effectiveness. Currently, the increase of antimicrobial resistance (AMR) is one of the biggest threats to global health. For this reason, the aim of the study was to investigate prevalence of the microbiological causes of canine otitis externa and the antibiotic susceptibility of the isolated bacterial strains. The research and sampling were conducted at Veterinary Clinics for small pets in Serbia. Samples were sent to laboratory for bacteriological and mycological testing. Additionally, the sensitivity of the isolated bacteria to antibiotics was evaluated using disc diffusion method. Sixty dogs with otitis externa clinical symptoms were included in the study. Out of a total of 53 positive samples for pathogen presence, bacteria were present in 40. The most prevalent bacteria was Staphylococcus pseudintermedius, followed by Pseudomonas aeruginosa and Proteus spp., while Malassezia pachydermatis was the only isolated yeast pathogen occurring in 36 samples. Generally, the lowest resistance against all bacteria showed enrofloxacin. On the contrary, high resistance to penicillin and amoxicillin was a common finding for G+ and G- bacteria. These results indicate the need for laboratory testing in terms of isolation, identification and antibiotic susceptibility testing, not only in the case of otitis externa in dogs, but in all diseases when it is possible, in order to enhance antimicrobial stewardship and consequently to contribute AMR reduction.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"26 3","pages":"449-459"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41161742","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}
