Virulence factors are cellular structures, molecules and regulatory systems that enable microbial pathogens to achieve the following: colonization of a niche in the host immunoevasion, evasion of the ...

What is an example of a virulence factor?

Factors that are produced by a microorganism and evoke disease are called virulence factors. Examples are toxins, surface coats that inhibit phagocytosis, and surface receptors that bind to host cells.

What are virulence factors explain?

Virulence factors are bacteria-associated molecules that are required for a bacterium to cause disease while infecting eukaryotic hosts such as humans. A surprisingly large number of virulence factors are encoded by prophage infecting bacterial pathogens, such as cholera toxin, Shiga toxin, and diphtheria toxin.
