Virulence factors are structures of organisms that helps in establishment of disease. During infection virulence factors encounter with the defense mechanism of the host and if they overcame infection is established or else the microorganism is eliminated. Pathogenicity of microorganism depends on the nature and type of virulence factors. The virulence factors are the following:
1) structural factors or attachment factors or adhesin
Capsule
Pili
Lipoteichoic acid
Biofilm producing glycocalyx
2) enzymatic factors or spreading factors
Collagenase
Protease
Deoxyribonuclease
Fibrinolysin
3) toxin
a) exotoxin- neurotoxin - tetanus toxin produced by Botulinum tetani
b) endotoxin- lipopolysaccharide of outer membrane of gram positive bacteria
4) antiphagocytic property
Capsule
Superoxide dismutase
