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.

Key words: Salmonella; colicins; serovars; human; animal; environment; food; animal feed

RESUMO

Investigou-se a produção de colicina em 748 amostras de Salmonella (97 sorovares) advindas de díferentes fontes: humana (291), animal (119), ambiental (141), de alimentos (102) e rações (95). Detectaram-se 64 amostras (8,6%) colicinogênicas, particularmente isoladas de alimentos (30,4%). ColE1 (53) e Ia (44) foram as mais freqüentes, especialmente no sorovar S, agona, de origem ambiental e de alimentos. Identificou-se também a produção de col V em 5 amostras de S. typhimurium dentre 8 culturas produtoras de origem humana. Discute-se a relação entre a capacidade colicinogênica e as fontes e sorovares de Salmonella.

Palavras-Chave: Salmonella; colicinas; sorovares; origem humana; animal; ambiente; alimento; ração
