Pathogenicity of 31 field strains of infections bursal disease viruses isolated during 1997-2001 in China was compared in SPF chickens at different ages.

为了弄清我国各地流行的IBDV毒力程度，在3—7周龄SPF鸡进行人工感染的致病性试验，以此比较研究了1997—2001年期间从我国不同地区分离到的31个IBDV野毒株。

Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation.

病毒抗原可以从鸭的盲肠，扁桃体，肾脏及粪便分离出来，并且确定这种病毒是高致病性的H5N1，还从血凝素蛋白分解位点推断出病毒的氨基酸序列，为了了解独立群的发病机理，对8只6周龄鸡静脉注射这种病毒，结果所有的均在注射后24小时死亡。
