Colicinogeny in Salmonella serovars isolated in Brazil

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.
