Fimbriae of Human Enterotoxigenic , and Control of their Expressionion is acquired by ingesting contaminated food or water. Two virulence attributes of ETEC are essential for pathogenicity, namely enterotoxin production and the ability to adhere to and to colonize the epithelium of the small intestine. Bacterial growth . and elaboration of enterotoxin(s) leads to i

At lower temperatures or lower specific growth rates the production of fimbriae per unit of biomass rapidly decreases (9). In this study a combination of physiological a
