Resistance to infectious agents may depend upon innate mechanisms or acquired immune responses. Inflammation, phagocytosis, cell-mediated immunity and antibodies are components of a complex reaction which result either in resistance or in susceptibility. Most infectious organisms stimulate immune responses within every compartment of the immune system. In rather few infections of poultry, it is possible to pinpoint a limited number of immune reactions that are primarily responsible for resistance. In some situations, autoimmunity may contribute to the pathology associated with infections.
对传染原的抵抗力可能取决于先天机制或获得性免疫反应。炎症、吞噬作用、细胞介导的免疫和抗体是一个复杂反应的组成部分，其结果可能是产生抵抗力或易感性。大多数传染性生物体都会刺激免疫系统的各个部分产生免疫反应。在家禽的少数感染中，可以确定有限数量的主要负责抵抗力的免疫反应。在某些情况下，自身免疫可能会导致与感染相关的病理变化。
