Most effective bacterial system within phagocytes is-: (A) Lysozyme mediated, (B) Lactoferrin mediated, (C) Reactive oxygen metabolite mediated, (D) Cationic basic protein mediated
Answer is C. Ans. is `c i.e. Reactive oxygen metabolite mediatedMicrobial killing (bactericidal activity) is largely mediated by oxygen dependent mechanisms. The most effective/ efficient bactericidal system within phagocytes is the oxygen dependent (H202-MPO-Halide system that mediates bacterial killing by the generation of HOCI with the help of myeloperoxidase and H202.
