Pathogens produce virulence factors primarily to ______. A. change its environment B. maintain temp and pH values C. cause disease D. out compete host cells for resources


In this question virulence factors are secreted by the bacterial so that they can evade the host and fight against the host defense mechanism. These virulence factors causing the activation of some host enzymes that are non specific proteases and due to activation of that protease cell wall get dissolved and bacterial attach and colonize at that place. Virulence factors some time evade the host immune system and some time suppresses the host immune system. These factor helps to compete with host resource or defense. Here correct answer is d.

Successful evasion may lead to disease and environmental changes leads to biofilm formation that is done by quarum sensing.
