Web pathogenic bacteria have evolved exquisite mechanisms for colonising humans and replicating in the host. They can release toxins that damage tissues and cause illness.
A Pathogen Is Usually Defined As A Microorganism That Causes, Or Can Cause, Disease.
‘bacterial pathogenesis’ explains the stages of pathogenesis, virulence factors, the four groups of pathogenic bacteria (adhesins, aggressins, impedins, and invasins),.
