| 摘 要： | 对新近分离到的鹅源禽副粘病毒ＧＰＭＶ／ＱＹ９７－１株的生物学特性进行了研究。结果表明，该病毒粒子在电镜下呈球形，直径１２１～２５０ｎｍ，表面有纤突，能凝集鸡的红细胞，血凝反应能被Ｉ型禽副粘病毒阳性血清所抑制，由此初步判定该病毒属于Ｉ型禽副粘病毒，该病毒人工感染１、１４、２８、４８日龄的鹅，发病率均为１００％。致死率分别为１００％、８７．５％、６２．５％、１２．５％；人工感染２５日龄的鸡，发病率和致

| Abstract: | The biological characteristics of an avian para my xovirus isolate, strain
GPMV/QY97-1 showing pathogenicity to geese, were charac terized. The results were as
follows spherical virons 121-250 nm in diameter a nd surface covered with spikes were
observed under electron microscopy. The viru s could agglutinate chicken erythrocyes, and
the hemagglutination reaction could be inhibited by standard antiserum of paramyxovirus-1.
So the virus was identi fied as paramyxovirus-1. The morbidity of 1,14,28,48-day-old goose
challenged with GPMV/QY97-1 was 100%. and the mortality was 100%、87.5%、62.5%、12.5%,
r espectively. Both the morbidity and mortality of 25-day-old chicken challenged with
GPMV/QY97-1 was 100%. But ducks appeared to be not affected in artificial infection. |
