Most strains of Staphylococcus aureus produce the exoenzyme ____________, which exploits the natural mechanism of blood clotting to evade the immune system.
Answer (2)
Staphylococcus aureus produces the exoenzyme coagulase, which helps the bacterium evade the immune system by forming blood clots. This protective clot prevents immune cells from attacking the bacteria, enabling them to multiply and cause infections. Coagulase is a key factor in the pathogenicity of this bacterium.
;
Answer
Coagulase
Explanation
Staphylococcus aureus produces the exoenzyme coagulase, which enables the bacteria to exploit the natural blood clotting mechanism. Coagulase converts fibrinogen to fibrin, forming a clot around the bacteria, which helps them evade the host's immune system.
Role of Coagulase
Immune evasion : The clot formed around the bacteria protects them from phagocytosis and other immune responses.
Virulence factor : Coagulase is a key virulence factor that contributes to the pathogenicity of Staphylococcus aureus.
Conclusion
Coagulase is the exoenzyme produced by most strains of Staphylococcus aureus that enables them to manipulate the host's blood clotting mechanism for immune evasion. ;
