WebThe immune system comprises both innate and adaptive immune responses. Innate immunity occurs naturally because of genetic factors or physiology; it is not induced by infection or vaccination but works to reduce the workload for the adaptive immune response. Both the innate and adaptive levels of the immune response involve secreted … Web2 CHAPTER1—Innate immunity antagonism associated with the normal bacterial flora of the body. This suppresses the growth of many po-tentially pathogenic bacteria and fungi at superficial sites by competition for essential nutrients or by pro-duction of inhibitory substances. To give one example, pathogen invasion is limited by lactic acid ...
