The genetic control of resistance to RSV (RAV-50) in chick embryos inoculated via the chorioallantoic membrane route was studied in three breeds of chickens. The relative susceptibility to subgroup D infection was 0.01, 0.02 and 0.003 in broilers, White Leghorns and Bantam x Australorp crosses, respectively. The distribution pattern of putative dr gene frequencies were 0.80, 0.68 and 0.90, respectively, in the same three breeds. Liver tumours resulting from the virus infection were observed in a very few birds about 28 days after hatching.
通过绒毛尿囊膜途径接种鸡胚后，对三种品系鸡中抗呼吸道合胞病毒（RAV - 50）的遗传控制进行了研究。肉鸡、白来航鸡和矮脚鸡与澳洲黑鸡杂交种对D亚组感染的相对易感性分别为0.01、0.02和0.003。在相同的三个品系中，假定的dr基因频率分布模式分别为0.80、0.68和0.90。在孵化后约28天，在极少数鸡中观察到由病毒感染引起的肝肿瘤。
