How does coagulase help Staphylococcus aureus evade phagocytes?
A) It coats the surface of the bacterial cells with collagen, a tissue binding protein.
B) It coats the surface of bacterial cells with fibrin, a protein found in blood.
C) It causes formation of small clots in capillaries, slowing progress of phagocytes to the infected area.
D) It causes formation of small clots in capillaries, slowing progress of phagocytes to the infected area AND it coats the surface of bacterial cells with fibrin, a protein found in blood.
E) It causes formation of small clots in capillaries, slowing progress of phagocytes to the infected area AND it coats the surface of the bacterial cells with collagen, a tissue binding protein.

Question

Quizplus · Accepted Answer

Coagulase causes formation of small clots in capillaries, which slows the progress of phagocytes to the infected area. Additionally, coagulase coats the surface of bacterial cells with fibrin, a protein found in blood, which can prevent the bacteria from being recognized and engulfed by phagocytes.
