Host-Pathogen Interactions

Host pathogen interaction takes place between a pathogen and a host. An asymptomatic infection is the one in which pathogen resides in host without causing any harm; Microbes can be both hosts and pathogens and the studies of bacterial pathogenesis leads to the identification of molecular differences between a pathogenic and a non-pathogenic microbe. Virulence relies on host factors, like pathogenicity of an avirulent microbe in immune compromised host and also the missing of the pathogenicity of virulent pathogens in immune hosts. The measure of virulence is the ability of a microbe to cause disease in any animal, centralized to the Koch’s postulates.
