Clumping factor, coagulase, and protein A serve to coat Staphylococcus with host proteins.

Question

Quizplus · Accepted Answer

Clumping factor, coagulase, and protein A are virulence factors produced by Staphylococcus bacteria. These factors allow the bacteria to evade the host immune system by coating themselves with host proteins. Clumping factor causes blood cells to clump together, which helps the bacteria to evade detection by the immune system. Coagulase causes blood to clot, which can help to protect the bacteria from immune cells. Protein A binds to immunoglobulins, which are proteins that the immune system uses to recognize and attack foreign invaders. By coating themselves with host proteins, Staphylococcus bacteria can become less recognizable to the immune system and avoid detection.
