Heamagglutination tests were applied to detect virus in allantoic fluid of chicken embryos which were infected by b95 gathered from the vaccinated chickens " cloacal and oral cavity. the results show that the virus may be detected from 2 days to 11 days after the chicken being vaccinated. the hi antibodies were measured by heamagglutination inhibition tests. there is no significant difference between the immunized and the control chickens which were fed in one case. chickens were immunized with b95 by different immunization meathods or with different vaccines by the same meathod. lt is demonstrated that eyedrop, drinking water, spray or muscle injection all can stimulate good effects, but eyedrop and spray seem to be the best meathods. b95 immunized chicken have relatively higher hi titers and it also can last for a longer time than others
但如果兩者相隔10天以上免疫， b95免疫不受h120的影響；如果同時免疫b95和h120 ，加大b95的免疫劑量也能獲得良好的免疫效果。用棉拭子采b95免疫雞口腔、泄殖腔的分泌液，檢測其中病毒的存在，結果免疫后2 11天雞口腔和泄殖腔中均有病毒的存在，說明b95免疫雞帶毒時間長。研究結果表明， b95具有不受母源抗體干擾、 hi抗體產生快、水平高、持續時間長、同居擴散性強等特點，因此b95是一株優良的、具開發前景的新的新城疫疫苗株。 -
