Abstract

A study of colicinogeny was made in 748 strains of Salmonella (97 serovars) isolated from different sources: human (291), animal (119), environmental (141), food (102) and animal feed (95). Colicin production was detected in 64 strains (8.6%), particularly isolated from foods (30.4%). Col E1 (53) and Ia (44) were the most frequently observed, especially in S. agona for environment and food sources. Col V production was identified in 5 strains of S. typhimurium within 8 producer cultures isolated from humans. Its relationship with the sources and serovars of Salmonella are discussed.

摘要

对从不同来源分离出的748株沙门氏菌（97个血清型）进行了产大肠杆菌素研究：人类（291株）、动物（119株）、环境（141株）、食品（102株）和动物饲料（95株）。在64株菌株（8.6%）中检测到产大肠杆菌素，特别是从食品中分离出的菌株（30.4%）。最常观察到的是Col E1（53株）和Ia（44株），尤其是在来自环境和食品来源的阿哥纳沙门氏菌中。在从人类分离出的8株产大肠杆菌素培养物中的5株鼠伤寒沙门氏菌中鉴定出Col V的产生。讨论了其与沙门氏菌来源和血清型的关系。
