【摘要】 鸽I型副粘病毒 (PPMV Ⅰ )JS株的尿囊液毒 ,经 1 0倍连续稀释后分别接种鸡成纤维细胞和非免疫鸡胚 ,测定其半数细胞培养感染量 (TCID50 )和鸡胚半数感染量 (EID50 )。结果显示 ,JS株TCID50 为 1 0 - 9.33/0 .1mL ,EID50 为 1 0 - 9.375/0 .1mL ,表明JS株病毒对鸡胚和鸡胚成纤维细胞的易感性相近。更多还原

【Abstract】 After ten times continuous dilution,chicken embryo fibroblast (CEF) and chicken embryo were inoculated with pigeon Paramyxovirus Ⅰstrain JS for determining its median tissue culture infective dose(TCID 50 )and 50% egg infectious dose(EID 50 ).Results showed that TCID 50 and EID 50 of strain JS were TCID 50 =10 -9.33 /0.1mL and EID 50 =10 -9.375 /0.1mL,respectively. It suggested that determination data susceptivity of chicken embryo fibroblast (CEF) and chicken embryo were similar.更多还原
