How does the immune system respond to bacteria? What are the phases of the immune response? What is the immune response to parasitic infection? Bacteria may also be killed by phagocytes.
Opsonised bacteria are, therefore, coated with molecules that phagocytic cells recognise and respond to.
A type of protein in the immune system called complement protein attacks. Phagocytes recognize opsonized bacteria , engulfing and digesting them by phagocytosis. Once digeste epitopes are. Some staphylococcus bacteria live peacefully on human skin and membranes in a mutually beneficial relationship with their host, while others are able to exist far from a human host in soil or in water.
Humoral immunity is the principle specific immune response against extra-cellular bacteria which includes strong IgM responses are caused by polysaccharides and antibodies IgM and IgG against bacteria surface antigens and toxins stimulate three types of effector mechanisms – 1. There are several lines of host defence. When evaluating the cause of infection in any patient it is important to exclude non-specific immune defects.
