摘    要:2004年-2005年从黑龙江省11个地区鸡场、鸽场、鹅场疑似新城疫(ND)病死鸡、鸽、鹅体内分离到24株具有血凝活性的病毒,经HA、HI试验和电镜观察证实了13株病毒为NDV。其鸡胚平均死亡时间(MDT)和1日龄雏鸡脑内接种致病指数(IC-PI)分别为36.8 h~73.6 h和1.51~2.00之间,属于NDV强毒株或中强毒株。除HLJ-12-04株外,强毒株的血凝素热稳定性较差,属快速或中速血凝解脱型;弱毒株的血凝素热稳定性好,属慢速血凝解脱型。所有毒株均可较好地凝集鸡和人(O型血)的红细胞,但对其他动物的红细胞凝集性差异较大,对马和兔的红细胞凝集无规律。

关 键 词:新城疫病毒  分离鉴定  生物学特性

Abstract:13 strains of Newcastle disease virus(NDV),11 from vaccinated chickens and 2 from pigeons,were isolated from Heilongjiang Province during 2004-2005.All isolates' mean death time(MDT) of embryonated eggs,interacerebral pathogenicity index(ICPI),hemagglutination spectrum of erythrocytes, and hemagglutination-separation reactions were tested.The results showed that MDT of all NDV isolates were between 36.8 hours and 73.6 hours,ICPI were between 1.51 and 2.00,belonged to velogenic NDV.All 13 strains can agglutinate the erythrocytes of chicken and human O type.However,their ability of agglutinating erythrocytes of swine,horse,cow,rabbit and guinea pig were variable.Accept from HLJ-12-04,the hemagglutinin of lentogenic strains were stable to heat and belonged to slow type of agglutination-separation,virulent strains were not stable to heat and belonged to fast type of agglutination-separation.
Keywords:Newcastle disease virus  isolation and identification  biological characteristics
