Host Immune Response Paper
The host immune response to the attack
The immune response is activated the moment an infection is detected, neutrophils release antimicrobial substances viz. antimicrobial peptides, reactive oxygen species (ROS), reactive nitrogen species (RNS), protease and lysozymes. However, S. aureus presents a defense by releasing antioxidant enzymes like the catalase and superoxide dismutase which counteract ROS, RNS and their effects. The antimicrobial peptides have also been found to be neutralized and degraded by S. aureus. As a preventive measure S. aureus also destroys neutrophils through secretion of toxins. The bacteria further survives in the host by acquiring of nutrients from the host especially Iron (Fe). The major part of the iron (95%) is
