Question

Describe the major immune evasion strategies utilised by Staphylococcus
aureus during infection

Accepted Answer

∻Answer∻ ⚹ Staphylococcus aureus employs several strategies to evade the host immune system during infection. ⚹ ∻Solution∻ ‖ a ⋮ Protein A binding to Fc region of antibodies: S. aureus produces protein A, which binds to the Fc region of antibodies, preventing opsonization and phagocytosis. ‖ ‖ b ⋮ Secretion of toxins: It secretes toxins like alpha-toxin that can lyse host cells, including immune cells, aiding in immune evasion. ‖ ‖ c ⋮ Capsule formation: The bacterium can produce a polysaccharide capsule that inhibits phagocytosis by immune cells. ‖ ‖ d ⋮ Biofilm formation: S. aureus can form biofilms on surfaces, which protect the bacteria from immune cells and antibiotics. ‖ ∻Key Concept∻ ⚹ Immune evasion by Staphylococcus aureus ⚹ ∻Explanation∻ ⚹ Staphylococcus aureus utilizes multiple mechanisms such as protein A binding, toxin secretion, capsule production, and biofilm formation to evade the host's immune system and establish infection◊How do the surface proteins of Staphylococcus aureus help evade the host immune response⍭ Generate me a similar question◊⚹
