Abstract

Anaerobic facultative bacteria colonizing the intestinal tract of conventional rabbits fed three different diets (standard pellet, hay and pellet/hay mixture) were enumerated in brain heart infusion agar. Colony counts recovered from homogenized samples of small intestine, caecum and rectum differed with reference to the diet given. Among anaerobic groups, identified from rabbit fed pellet/hay mixture, Enterococci (E. faecalis, E. avium, E. faecium and E. durans) represented the predominant flora. Enterobacters (E. cloacae and E. aerogenes) accounted for about 10 to 25% of the bacteria in the rectum and colon respectively, whereas Staphylococci (S. intermedius, S. epidermidis and S. lentus) represented 11% of the bacteria isolated from colon.

摘要

在脑心浸液琼脂中对常规饲养的家兔肠道内定殖的兼性厌氧菌进行计数，这些家兔喂食三种不同的日粮（标准颗粒饲料、干草和颗粒饲料/干草混合物）。从小肠、盲肠和直肠的匀浆样本中回收的菌落计数因所给日粮的不同而有所差异。在家兔喂食颗粒饲料/干草混合物中鉴定出的厌氧菌中，肠球菌（粪肠球菌、鸟肠球菌、屎肠球菌和耐久肠球菌）是主要菌群。肠杆菌（阴沟肠杆菌和气肠杆菌）分别占直肠和结肠中细菌的约10%至25%，而葡萄球菌（中间葡萄球菌、表皮葡萄球菌和缓慢葡萄球菌）占从结肠分离出细菌的11%。
