Immunology of Infection
Immunology is a study of biology that covers the investigation of insusceptible systems in life forms. In regards to infectious disease, it is an “old associate’’ or developing risk, the immune system’s battle against the first line of defence it experiences. The immune system has built up with a number of ways which deals with controlling a viral and bacterial disease which directly kills the pathogen to complex cytokines that hinder replication. Pathogens have encountered by building up of immune evasion mechanisms that repress cytokine work and prevent resistant of tainted cells. With vaccines and effective medications, the immune system’s destroyed the infectious agents or infected cells. When microorganisms invade, their foreign macromolecules are recognized by pattern recognition receptors of the host, which initiate rapid innate immune responses (including phagocytes, cytokines and complement) followed by slower but very specific long-lasting acquired immune responses mediated...
