鸡减蛋综合症(EDS—76)病毒的分离和鉴定

HENS SYNDROME OF REDUCING LAY (EDS-76) SEPERATION IDENTIFICATION OF VIRUS

本文采集产蛋量突然下降的疑似发生EDS—76病鸡群中产软壳蛋鸡的输卵管为病料,经鸭胚传代,分离到一株血凝性病毒(FE_1株).该病毒株对氯仿不敏感,耐酸(PH3.0),通过与EDS—75—AV—127株及新城疫阳性血情所做的交叉血凝抑制试验表明,FE_1株与AV—127株的抗原性相同,而与新城疫病毒无抗原相关性.因此证明FE_1株端病毒属EDS—76病毒.

<ABSTRACT>: In this article,selected as researching material are the oviducts of the hens reducing theri lqywithin an unexpected spau of time with soft-shell eggs,and suspected that EDS-76 disease has happened tothem. By means of reproducing thiough ducks embryo,a alood-clotting virua has been reached (FE1plant),not sensitive to CHCL3,but acidproof(PH30),Hsing yt to make crossing inhhibition blood-cloting enperi-ments respectively with EDS-76-AV plant and ND-positiveserum reueals the antigencity of FE1 plant isthe same with that of AV - 127 plant,but different from ND virus,which,thus,has proved that FE1 plant dis-ease belongs EDS - 76 virus.
