Chickens from a line selected for high levels of plasma corticosterone when housed in an environment faciliating considerable social interaction were more resistant to Eimeria necatrix infection than those from a line selected for low levels of plasma corticosterone housed in an environment that minimized social interaction. Individuals in the high steroid group had a more active phagocytic defense and fewer schizonts than those in the low steroid group.
在一个促进大量社交互动的环境中饲养的、经选育具有高水平血浆皮质酮的品系的鸡，比在一个将社交互动降至最低的环境中饲养的、经选育具有低水平血浆皮质酮的品系的鸡，对毒害艾美耳球虫感染更具抵抗力。高类固醇组的个体比低类固醇组的个体具有更活跃的吞噬防御能力，并且裂殖体更少。
