摘　　要：2016年1月中下旬,华南地区某蓝鹇繁育基地蓝鹇亚成体发生流行性疾病,发病蓝鹇主要表现为精神沉郁、食欲废绝、羽毛蓬松凌乱、眼周水肿等症状。对死亡动物进行剖检,病理变化与流感病理变化相似,如心包积液,心外膜有出血点,肝脏充血、出血、肿胀,肺充血、出血,胰腺充血、出血或有白色点状坏死灶,腺胃乳头出血,肌胃角质膜下有出血斑,肾脏充血、出血、肿胀,肠道黏膜充血、出血等。经血凝(HA)和血凝抑制(HI)试验和实验室分子生物学诊断(RT-PCR鉴定),确诊为H9N2亚型禽流感病毒感染。虽及时采取治疗、紧急免疫和环境消毒等措施,死亡率仍高达47.6%。本文详细记录了救治程序和病程,并针对发病原因进行剖析,认为免疫、气候和饲养环境是引起本次该群蓝鹇发病的主要因素,为控制蓝鹇H9N2亚型禽流感提供参考。An epidemic disease was recorded among sub-adult Taiwan blue pheasant(Lophura swinhoii)in a Taiwan Blue Pheasant Breeding Base of south China.The infected pheasants showed clinical symptoms including reduced activity levels,loss of appetite,fluffy and messy feathers,and edema of eye.Autopsies showed that typical pathological changes were similar to those caused by influenza.The results of hemagglutination/hemagglutination inhibition(HA/HI)tests and laboratory molecular biology diagnosis found that these pheasant were infected with H9N2 subtype influenza virus.Although many measures have been implemented,such as timely treatment,emergency immunization and environmental disinfection,the death rate still reached up to 47.6%.We recorded in detail the course of the disease and treatment measures,and we found that the main factors causing infection by H9N2 influenza virus were climate,immunity,and breeding environment.These results might provide reference for controlling the Taiwan blue pheasant H9N2 subtype influenza virus.
