Colicinogeny in Salmonella serovars isolated in Brazil

[摘要] 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. typhimuriumwithin 8 producer cultures isolated from humans. Its relationship with the sources and serovars of Salmonella are discussed.
