Avian encephalomyelitis virus ( aev ) is a picornavirus with a predilection for the central nervous system and other parenchymous organs of chickens that is transmited by the oral - faecal route . the virus may be spread by the vertical and horizontalroutes , and because of its great stability , contaminated areas may remain infectious for long periods . the egg - adapted van roekel strain is highly neurotropic and does not grow efficiently in the enteric tract of the chicken , and the field isolates of aev is usually enterotropic . despite this . the virion polypeptides of both naturally - occurring strains and the van roekel strain are antigenically identical 侵害雞的中樞神經系統和其它實質性器官,該病毒通過口-糞途徑傳播,具有水平和垂直傳播的能力。由于它極大的穩定性,被污染的區域可能長期保持傳染性。雞胚適應株vanroekel是高度嗜神經的,并且在雞的腸道內不能有效的生長,而野毒株卻是嗜腸道型的。
