This study aimed to assess the prevalence of MRS and anti-microbial resistance patterns at a university clinical hospital in Madrid, Spain. Samples were collected from both the environment and hospital staff at Veterinary Clinical Hospital of Alfonso X el Sabio University. Anti-microbial susceptibility assays, molecular detection of mecA gene and genetic relationships among the identified bacterial strains were performed. The study revealed an MRS prevalence of 1.50% in environmental samples, with MRSP accounting for 0.75% of the cases. Genetically related MRSP strains were found in different hospital areas. Among hospital staff, there was a MRS prevalence of 14.03%, including S. pseudintermedius and S. epidermidis strains. Antibiogram tests revealed multi-drug resistance among MRSP strains. Additionally, methicillin-resistant coagulase-negative staphylococci were isolated, suggesting potential cross-species transmission. This study underscores the presence of MRS in a veterinary clinical hospital, highlighting the significance of infection control through the implementation of protective measures, stringent hygiene practices among personnel and in the environment and responsible use of antibiotics. Further research is necessary to assess MRS incidence in animal patients and explore geographical variations, enhancing our understanding of MRS in veterinary medicine and addressing its challenges.","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"15 7","pages":"325-334"},"PeriodicalIF":0.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11383197/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142296898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep eye discharge, nostril, cutaneous ulcers and lymph fluid swabs were cultured, and polymerase chain reaction (PCR) was carried out. Eleven horses were CFT-positive. Based on the malleination on the 11 horses, six were affected by glanders, five were not affected (false positive), and one horse was CFT-negative despite exhibiting clinical signs. It was positive by malleination, ELISA and PCR. A total number of seven positive cases of glanders were diagnosed. The B. mallei could not be isolated, but the Burkholderia cepacia complex was isolated in one case. Except for three cases, the results of the CFT, mallein and ELISA tests were consistent. The amount of confidence interval was 95.00%. It is suggested that ELISA could be used as a complement to CFT in screening and, if positive results are observed in one of the tests, the entire herd must be examined more accurately using the mallein and western blot confirmatory tests.","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"15 5","pages":"231-236"},"PeriodicalIF":0.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11251541/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141634735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the prevalence and antimicrobial resistance (AMR) patterns of S. aureus in mastitic milk samples collected from camel farms in Matrouh Governorate, Egypt. A total of 200 mastitic camel milk samples were evaluated for S. aureus using both conventional culture-based and molecular-based methods. Antibiotic susceptibility testing of S. aureus isolates was conducted using disc diffusion and agar dilution methods, with antibiotic resistance genes identified through polymerase chain reaction with specific primers. Out of samples tested, 60 (30.00%) were positive for S. aureus. The isolates displayed the highest of resistance against piperacillin-tazobactam (55.00%) followed by trimethoprim- sulfamethoxazole (45.00%) and amoxicillin (40.00%). Half of the isolates were multidrug-resistant (MDR). The AMR genes included methicillin-resistant gene (mecA), β-lactamase gene (blaZ), tetracycline resistance gene (tetK), erythromycin resistance gene (ermB) and vancomycin resistant gene (vanA) were detected in 100%, 100%, 95.00%, 90.00% and 20.00% of the isolates, respectively.

To compare the paralytic effects of selected AGs on some motor behaviors in mice, 24 male mice were divided into four groups. Each group was given one of AGs (gentamicin, dihydro-streptomycin, apramycin and amikacin) at incremental doses that increased half-logarithmically compared to the therapeutic dose (16.00 mg kg-1). Motor behavioral tests included open field test, inclined plane, horizontal bars, static rods, parallel bars and rotarod. Finally, the data were analyzed using descriptive and analytical statistics. Gentamicin and dihydrostreptomycin at 32.00 times of the therapeutic dose produced complete paralysis of the limbs, respiratory arrest, and even death in some animals. However, apramycin and amikacin did not show significant effects on skeletal muscle and motor behaviors at 32.00 times of the therapeutic dose. After administration of apramycin at 100 times of the therapeutic dose, four out of six mice (66.67%) died from respiratory depression. Amikacin at this dose did not cause animal death, although it caused some changes in motor behaviors with a significant difference in comparison with control values. Gentamicin demonstrated significantly more potent effects on motor behaviors compared to the other AGs. Overall, the order of potency was gentamicin > dihydrostreptomycin > apramycin > amikacin. High doses of AGs could impair the skeletal muscle function and disrupt motor behaviors in mice.

The results showed that acetaminophen toxicity increased the serum levels of aspartate aminotransferase, alanine aminotransferase, urea and uric acid in the pigeons. Nanocurcumin treatment of acetaminophen intoxicated pigeons attenuated increases in biomarkers of the liver and kidney functions towards control levels. Also, the consumption of nanocurcumin minimized histopathological changes in the liver and kidney. A mortality of 60.00% was seen in the acetaminophen-induced toxicity group; while, none of the birds treated with nanocurcumin died.

The material for the study was the gallbladder wall's fragments of an adult Anglo-Nubian goat. Further processing of the obtained samples was carried out to acquire histological preparations. Ultra-thin sections were photographed in a Jem-1011 electron microscope at magnifications of 2,500 - 3,000. It was found that the gallbladder mucous membrane of an Anglo-Nubian goat is formed by the epithelial layer and its own lamina. The epithelial layer is represented by a single-layer prismatic epithelium. The nuclei are light, with clear contours. The apical surface of epithelial cells forms microvilli and the cytoplasm of the apical pole of cells contains many electron-dense secretory granules. The lateral surfaces of the cells in their apical part are interconnected by tight contacts. The lamina propria is formed by loose connective tissue containing many blood vessels and nerve fibers. Referring to the scientific literature describing possible pathologies of the gallbladder, we can conclude that the picture presented in the results generally corresponds to the position of the gallbladder without pathologies.","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"15 3","pages":"165-169"},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11102583/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141072180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
