Abstract

A total of 308 samples of different types were examined for the presence of salmonellas by means of three different procedures. The first consisted of pre-enrichment in buffered peptone water followed by enrichment in Rappaport-Vassiliadis medium (P/RV). The second differed only in that 1% Teepol was added to the pre-enrichment medium (PT/RV). In the third, buffered peptone water with 1% Teepol was followed by enrichment in Muller-Kauffmann tetrathionate broth also containing 1% Teepol (PT/MKT). The first of these combinations (P/RV) proved superior to the others both in terms of isolation rates and in the appearance of suspicious colonies.

摘要

通过三种不同的方法对总共308份不同类型的样本进行了沙门氏菌检测。第一种方法是先在缓冲蛋白胨水中进行预富集,然后在Rappaport-Vassiliadis培养基(P/RV)中进行富集。第二种方法的唯一不同之处在于,在预富集培养基中添加了1%的吐温80(PT/RV)。第三种方法是先在含有1%吐温80的缓冲蛋白胨水中进行预富集,然后在同样含有1%吐温80的Muller-Kauffmann四硫磺酸盐肉汤(PT/MKT)中进行富集。就分离率和可疑菌落的出现情况而言,这些组合中的第一种(P/RV)被证明优于其他组合。
