Abstract

The relative efficiency of three selective enrichment broths (Muller-Kauffmann tetrathionate. Rappaport's and selenite F) was investigated for the isolation of salmonellae from seagull cloacal swabs. Pre-enrichment in buffered peptone water was employed throughout the study, which involved the examination of 560 gulls, sixty (10.7%) of which were found to be carrying salmonellae. Rappaport's broth as modified by Vassiliadis for incubation at 43 degrees C (Vassiliadis et al. 1976) yielded the highest number of positive swabs (57) and the widest range of serotypes. It was significantly more efficient that either selenite F or tetrathionate broth, although the results obtained with Rappaport's broth incubated at 37 and 43 degrees C did not differ significantly (P greater than 0.5). Eleven serotypes were isolated during the study, the most prevalent being Salmonella virchow.

摘要

研究了三种选择性增菌肉汤(穆勒 - 考夫曼四硫磺酸盐肉汤、拉帕波特肉汤和亚硒酸盐F肉汤)从海鸥泄殖腔拭子中分离沙门氏菌的相对效率。在整个研究中均采用缓冲蛋白胨水进行预增菌,该研究共检查了560只海鸥,其中60只(10.7%)被发现携带沙门氏菌。经瓦西利亚迪斯改良用于在43℃培养的拉帕波特肉汤(瓦西利亚迪斯等人,1976年)产生的阳性拭子数量最多(57个),血清型范围最广。它比亚硒酸盐F肉汤或四硫磺酸盐肉汤的效率显著更高,尽管在37℃和43℃培养的拉帕波特肉汤所获得的结果差异不显著(P大于0.5)。在研究期间分离出11种血清型,最常见的是猪霍乱沙门氏菌。
