Pathogenesis is a process in which several types of microorganisms cause a disease .The pathogens encounter on body cell .
The pathogens generally damage to host by following ways
1)They use host nutrient s for the pathogenesis.
2) by causing direct damage in the immediate vicinity of the invasion.
3) they are able to produce toxins and produced toxin circulated by blood and another secretion is lymph
4) They remove damage site from original sites
5) They also able to induce hypersensitivity reactions .
Example : in rheumatic fever infection occur by streptococcus pyogenes .
