The ability of vibrio cholerae to cause disease depends on a number of factors. What are general requirements for any organism to cause disease within a host?

Disease

Explanation:

Pathogenicity is the ability to produce disease in a host organism Microbes express their pathogenicity by means of their virulence, a term which refers to the degree of pathogenicity of the microbe The relationship between a host and a pathogen is dynamic, since each modifies the activities and functions of the other The outcome of such a relationship depends on the virulence of the pathogen and the relative degree of resistance or susceptibility of the host, due mainly to the effectiveness of the host defense mechanisms Hence, general requirements for any organism to cause disease within a host are: evasion of host defenses, gaining access to the host via a portal of entry, adherence to host tissues
