Abstract
The incidence of salmonellae in contrasting environments was compared in this study. Samples collected from or near surface waters in a lush hardwood forest yielded four salmonellae serotypes from six culturally positive samples. A total of 76 samples collected from the top of a granite outcropping over a 3-month period yielded 10 positive samples. Only two salmonellae serotypes were isolated, and one of these was isolated only once. The nature of the sample material had no significant effect on the detection of salmonellae from the two sampling sites. However, the presence or absence of visible moisture in the sample significantly affected the recovery of salmonellae. The results showed that even a harsh environment such as that found on top of Stone Moutain may serve as an ecological niche for the survival and transmission of salmonellae.
摘要
本研究比较了不同环境中沙门氏菌的发生率。从茂密硬木森林地表水或其附近采集的样本中，6个培养阳性样本产生了4种沙门氏菌血清型。在3个月的时间里，从花岗岩露头顶部采集的76个样本中，有10个样本呈阳性。仅分离出两种沙门氏菌血清型，其中一种仅分离到一次。样本材料的性质对两个采样点沙门氏菌的检测没有显著影响。然而，样本中可见水分的有无显著影响沙门氏菌的回收率。结果表明，即使是像石山山顶那样恶劣的环境，也可能成为沙门氏菌生存和传播的生态位。
