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
幼雞感染該病毒后，引起麻痹、頭頸震顫甚至共濟失調，而成雞常呈亞臨床感染或導致產蛋量和孵化率下降。病毒的感染性不受氯仿、低ph 、胃蛋白酶、胰酶和脫氧核糖核酸酶的影響，鎂離子可增強病毒對熱的穩定性，病毒的浮密度為1 . 31g ml ，直徑為22 - 30nm ，該病毒主要在雞胚中增殖，在大多數細胞培養物中不生長。
