补充资料:鸡新城疫
鸡新城疫 New Castle disease 由副粘病毒引起的高度接触性传染病。又称亚洲鸡瘟或伪鸡瘟 。常呈急性败血症状 。主要特征是呼吸困难、便稀、神经紊乱、粘膜和浆膜出血。死亡率高,对养鸡业为害严重。1926年首先发现于印度尼西亚,不久又在英国新城发现,世界各国均有流行记载。有强毒株和弱毒株两类。病毒分为低毒力型(即缓发型)、中等毒力型(即中发型)、强毒力型(即速发型)3型。多数高强度毒力株常属嗜内脏型新城疫病毒。鸡科动物都可患罹本病。家鸡最易感,雏鸡比成年鸡易感性更高。珠鸡、火鸡、雉、孔雀也能感染。鸭、鹅对本病有抵抗力。哺乳动物对本病有强大抵抗力,但人偶有感染而患结膜炎。急性型病初体温升高 ,可达 44℃,精神萎顿,羽毛松乱,呈昏睡状。冠和肉髯暗红色或黑紫色。嗉囔内常充满液体及气体 ,呼吸困难,喉部发出咯咯声;粪便稀薄、恶臭,一般2~5天死亡。亚急性或慢性型症状与急性型相似,唯病情较轻,出现神经症状,腿、翅麻痹,运动失调,头向后仰或向一边弯曲等 ,病程可达1~2个月,多数最终死亡。尚无有效治疗药物,只能依靠严格消毒、隔离和用灭活苗和活苗疫苗接种预防。 |
