一株鹅副黏病毒的毒力测定

Virulence Test of Geese Paramyxovirus

鹅副黏病毒病是1997年扬州大学王 永坤教授等发现的一种新的鹅的烈性传染 病,该病使10日龄以内的雏鹅发病率和病死 率均达到100%,平均发病率和病死率分别为 27.7%和18.2%。为了有效防制该病的传播 和流行,用非免疫鸡胚,从一群病死鹅的脑组 织中分离到一株病毒,该病毒能使鸡红细胞 发生凝集,而且这种凝集能被鸡新城疫标准 阳性血清所抑制。通过进一步对该病毒进行 回归试验、MDT、ICPI、IVPI及其他生物学特性试验,证实该分离株为鹅副黏病毒 (GPMV)中等毒力毒株。

A new viral disease of goose was reported by Wang Yongkun etc. This disease showed high morbidity and mortality, the average rates of which were 27.7% and 18.2% respectively,and the baby goose within 10 days old couldn't avoid absolutely.In order to control this disease,a virus strain was isolated from brains of dead geese,which were not immunized in the embryo stage.This virus strain could agglomerate chicken erythrocytes,and this agglutination could be inhibited by Newcastle disease virus antiserum. The recurrent infection,MDT,CIPI,IVPI and the other biological property tests indicated that this virus strain belonged to a mesogenic virus strain of Geese PMV-Ⅰ.
