RESUMO
Nineteen Plesiomonas shigelloides strains were evaluated for their stability at acidic and slightly alkaline pHs and for their susceptibility to antimicrobial agent-like compounds produced by enteric flora. Most P. shigelloides isolates were rapidly inactivated under high-acid (pH 4 or less) conditions. Screening of enteric bacteria for elaboration of factors active against P. shigelloides revealed two organisms (Pseudomonas aeruginosa and Streptococcus [Enterococcus] faecium) capable of secreting such inhibitory substances. The results of this study suggest some factors potentially important in regulating gastrointestinal colonization by P. shigelloides from environmental sources.
