virulence factors

Factors essential for the pathogenicity of bacteria. In the case of Vibrio cholerae , for instance, the virulence factors are cholera toxin and the toxin coregulated pilus which is necessary for V. cholerae to colonize the intestine. A small molecule has been found that can inhibit the production of both of these factors without affecting the reproduction of the organism.
