| 摘 要： | 通过SPF鸡致病性试验、MDT、ICPI、血凝解脱速率和血凝素热稳定性试验 ,结果表明 ,从山东分离的鸡新城疫病毒S1株与Lasota、F4 8E8间存在生物学差异。对S1株的鸡胚增毒量进行了研究 ,结果显示 ,10 3 5EID50 接毒量既不影响病毒的增殖量也不影响其感染性

| Abstract: | The low virulent Newcastle disease virus S 1 strain isolated from laying hens in Shandong Province was pathotyped and characterized by challenge with specific pathogen free (SPF) chickens, mean death time (MDT) of embryos, intracerebral pathogenicity index(ICPI), elution rate from chicken erythrocytes and hemagglutinin thermostability The results showed that there were biological differences between NDV-Lasota and F 48 E 8 stain virus In addition, the effect of amount of S 1 strain virus inoculated into 11 day-age SPF embryos on its propagation was determined The data indicated 10 35 EID 50 of seed virus would be optimal and not influence the infectivity of S 1 strain |
