新城疫疫苗 meaning in English
newcastle disease vaccine
Examples
- Researchers in the united states have developed one for ( newcastle ) disease in chickens , but so far there are no products for humans
美国的研究人员已经研制出了一种鸡新城疫疫苗，但到目前为止适合人类的产品。 - 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
但如果两者相隔10天以上免疫， b95免疫不受h120的影响；如果同时免疫b95和h120 ，加大b95的免疫剂量也能获得良好的免疫效果。用棉拭子采b95免疫鸡口腔、泄殖腔的分泌液，检测其中病毒的存在，结果免疫后2 11天鸡口腔和泄殖腔中均有病毒的存在，说明b95免疫鸡带毒时间长。研究结果表明， b95具有不受母源抗体干扰、 hi抗体产生快、水平高、持续时间长、同居扩散性强等特点，因此b95是一株优良的、具开发前景的新的新城疫疫苗株。
