摘要

鼠伤寒沙门氏菌在世界范围内被广泛认为是人类沙门氏菌病的常见原因,食用动物是重要的宿主。本研究旨在确定和比较从桑戈-太田县山羊和牛粪便中分离出的鼠伤寒沙门菌的流行情况,并确定分离出的微生物的抗菌敏感性。采用标准微生物学和生化方法,对157份新鲜粪便样本(山羊50份,牛107份)进行鼠伤寒沙门菌检测。检出鼠伤寒沙门菌22例(14%),检出鼠伤寒沙门菌13例(8.28%),其中牛检出鼠伤寒沙门菌19例(86.4%),山羊检出3例(13.6%),牛检出鼠伤寒沙门菌12例(92.31%),山羊检出沙门菌1例(7.69%)。另外分离出柠檬酸杆菌、普罗维登斯氏菌、假单胞菌、变形杆菌、克雷伯氏菌、耶尔森氏菌、摩根氏菌、肠杆菌、大肠杆菌和沙雷氏菌。药敏试验显示,大多数分离物对氧氟沙星、环丙沙星、培氟沙星、庆大霉素和萘啶酸敏感。大多数鼠伤寒沙门菌、沙门氏菌和其他细菌分离株对本研究中使用的所有氟喹诺酮类药物敏感。大多数分离株对阿莫西林、氨苄西林、augmentin、复方新诺明、链霉素、四环素和本研究中使用的所有头孢菌素耐药。在桑戈-太田,牛和山羊的粪便中都存在鼠伤寒沙门氏菌,因此,如果对这些来源的食物处理不当,就可能导致该有机体的传播和食源性沙门氏菌病的发生。

Comparison Of Prevalence And Antimicrobial Sensitivity Of Salmonella typhimurium In Apparently Healthy Cattle And Goat In Sango-Ota, Nigeria
Salmonella typhimurium has been extensively incriminated worldwide as common causes of Salmonellosis in humans, with food-animals serving as important reservoirs. This study was aimed at determining and comparing the prevalence of Salmonella typhimurium isolated from faeces of goats and cattle in Sango-Ota and also at determining the antimicrobial sensitivity of the isolated organisms. A total of 157 fresh faecal samples (50 from goat and 107 from cattle) were examined for the presence of Salmonella typhimurium using standard microbiological and biochemical methods. 22 (14%) of the total samples were positive for Salmonella typhimurium and 13 (8.28%) were positive for Salmonella spp. 19 (86.4%) of Salmonella typhimurium were isolated from cattle while 3 (13.6%) from goats while 12 (92.31%) of Salmonella spp were isolated from cattle while 1 (7.69%) from goats. Other organisms isolated were Citrobacter spp, Providencia spp, Pseudomonas spp, Proteus spp, Klebsiella spp, Yersinia spp, Morganella spp, Enterobacter spp, Escherichia coli and Serratia spp. Antibiotic susceptibility test revealed that majority of the isolates were susceptible to ofloxacin, ciprofloxacin, pefloxacin, gentamicin, and nalidixic acid. A majority of Salmonella typhimurium, Salmonella spp, and other bacterial isolates were susceptible to all fluoroquinolones used in this study. A majority of the isolates were resistant to amoxicillin, ampicillin, augmentin, cotrimoxazole, streptomycin, tetracycline, and all cephalosporins used in this study. Salmonella typhimurium was present in both cattle and goat faeces in Sango-Ota and therefore if food from these sources are not properly handled it could lead to spread of the organism and occurrence of food borne salmonellosis.
