鸡新城疫又被称为亚洲鸡瘟,主要是由禽副流感病毒型病毒所引起,对鸡、火鸡、野禽及观赏鸟类造成侵害,体现出高度接触传染性以及致死性的疾病特点。家禽在受到侵害发病之后,会出现呼吸困难,下痢,伴有神经症状,成鸡的产蛋量降低以及粘膜和浆膜出血的特征,并有着感染率高和致死率高的情况。现今,该病无有效的药物进行治疗,主要通过接种疫苗进行预防该病的发生。本文对鸡新城疫的病原学、临床症状、病理剖检变化、诊断及防治进行综述,为鸡新城疫综合防治提供基础。
Newcastle disease, also known as chicken plague in Asia, is caused mainly by the avian parainfluenza virus and causes damage to chickens, turkeys, wild birds and ornamental birds, reflecting the highly contagious and lethal disease characteristics. After poultry are infested, dyspnea, diarrhea, neurological symptoms, reduced egg production, and mucosal and serosal bleeding may occur with high rates of infection and high lethality. Nowadays, the disease is treated with no effective drugs, mainly through vaccination to prevent the occurrence of the disease. This article reviews the etiological, clinical symptoms, pathological changes, diagnosis and prevention of Newcastle disease and provides a basis for the comprehensive prevention and control of Newcastle disease.
