摘要
鹅星状病毒主要感染3周龄以内的雏鹅,感染初期会表现食欲下降、精神不振、四肢无力,随着病情恶化会出现排泄物呈白色、小腿关节肿大、尿酸沉积及瘫痪等症状,发病率较高,死亡率高达30%,给我国养鹅业造成了严重危害。本文从病原学、流行病学与致病性、症状表现、实验室诊断、防控、展望等六个部分对鹅星状病毒病展开综述。取病料进行鹅胚接种、病毒传代培养等方法分离病毒,用RT-PCR等方法鉴定病毒,经非易感动物多代传代有望培养出有效的弱毒疫苗。在实际生产中,建议从业者通过注射有效疫苗、切断传播途径和合理使用药物等措施防治鹅星状病毒病。
The goose astrovirus mainly infects the goslings within 3 weeks old. At the initial stage of infection,goslings show loss of appetite,listlessness and weakness of limbs. As the disease deteriorates,they show symptoms such as white feces,swelling of leg joints,uric acid deposition and paralysis,etc. The high incidence and up to 30%mortality rate would cause serious harm to the goose industry in China. In this article,it reviews the research process of goose astrovirus disease from six parts:etiology,epidemiology and pathogenicity,symptomatology,laboratory diagnosis,prevention and control,and prospect. The astrovirus was separated by taking diseased material for goose embryo inoculation and virus transmission culture,and identified by RT-PCR and other methods. It is expected that an effective attenuated vaccine will be cultivated by multi-generation subculture in non-susceptible animals. Practitioners are recommended to prevent and control goose astrovirus disease through measures such as injecting effective vaccine,cutting off the transmission route and rational use of drugs in the geese production.
