In young chickens aev induces paralysis , ataxia and muscular dystrophy , while in older chickens , infection is usually subclinical , resulting in a decline in egg production and hatchability . infectivity was shown to remain unaffected by chloroform , low ph , pepsin , trypsin and deoxyribonuclease . magnesium cations were shown to stabilise preparations of the virus against heat inactivation . the buoyant density of virions are 1 . 31g / ml . the diameter of the virion was estimated to be 22 to 30nm . the aev can be adapted to grow in chicken embryo . the inability of aev to grow effeciently in most cell cultures 幼鸡感染该病毒后，引起麻痹、头颈震颤甚至共济失调，而成鸡常呈亚临床感染或导致产蛋量和孵化率下降。病毒的感染性不受氯仿、低ph 、胃蛋白酶、胰酶和脱氧核糖核酸酶的影响，镁离子可增强病毒对热的稳定性，病毒的浮密度为1 . 31g ml ，直径为22 - 30nm ，该病毒主要在鸡胚中增殖，在大多数细胞培养物中不生长。
