一例从国内鹦鹉鉴定到鹦鹉博尔纳病毒2型的诊断研究

A Case Study on the Diagnosis of Parrots Bornavirus-2 fromIdentification in China

为探究一例非洲灰鹦鹉死亡原因。本研究通过临床症状、病理变化以及分子检测等方法对一例非洲灰鹦鹉的死因进行了分析诊断。该鹦鹉生前即出现食欲下降、精神萎靡和呕吐等症状,死后剖检观察到腺胃扩张且胃内有未消化食物并伴酸臭味,胃壁变薄,脑部充血等现象,通过病理切片及分子诊断显示,该鹦鹉感染了博尔纳病毒。通过测序及进化树分析表明,该鹦鹉感染的博尔纳病毒为鹦鹉博尔纳病毒2型,为国内首次发现。本研究为该病毒的诊断提供了依据,并为该病的防控提供了参考。

To explore the cause of death of an African grey parrot.This study analyzed and diagnosed the cause of death of a case of African grey parrot through clinical symptoms,pathological changes and molecular detection.The parrot had symptoms of appetite loss,lethargy,vomiting and so on before death.Postmortem examination showed that the glandular stomach was dilated,undigested food in the stomach was accompanied by sour odor,the stomach wall was thin,and the brain was hyperemia.Pathological biopsy and laboratory molecular di-agnosis showed that the parrot was infected with Borna virus.Sequencing and evolutionary tree analysis showed that the infected Borna virus was parrots Bornavirus-2,which was found for the first time in China.This study provides a basis for the diagnosis of the virus and a reference for the prevention and control of the disease.
