Detailed explanation-1: -Adherence and Colonization Factors. To cause infection, many bacteria must first adhere to a mucosal surface. Invasion Factors. Capsules and Other Surface Components. Endotoxins. Structure of Endotoxin.
Detailed explanation-2: -Virulence is described as an ability of an organism to infect the host and cause a disease. Virulence factors are the molecules that assist the bacterium colonize the host at the cellular level. These factors are either secretory, membrane associated or cytosolic in nature.
Detailed explanation-3: -Toxins. A major category of virulence factors are bacterial toxins. These are divided into two groups: endotoxins and exotoxins.
Detailed explanation-4: -Virulence factors characterized as important for attachment and invasion in human infection are CPS, -hemolysin, C proteins, and pilus-like proteins. Experimental models of infection have demonstrated that antibodies to these surface structures are protective.
