鹿源多杀巴氏杆菌荚膜分型及免疫原性
CHINESE JOURNAL OF VETERINARY SCIENCE（2003）
Abstract
采用Carter荚膜群鉴定法将分离于我国鹿的38株多杀巴氏杆菌进行鉴定,结果显示:B型占68.4%(26/38),A型占18.4%(7/38),D型占5.3%(2/38),3株未能确定型占7.9%(3/38).并从26株荚膜B型巴氏杆菌中选出荧光典型的8株菌制备免疫原给健康兔注射,30 d后用间接血凝法测定各株菌抗体效价,选出效价最高的2株菌D1PM和D2PM用小鼠增毒,当毒力稳定后用兔测得D1PM MLD为8个菌,D2PM MLD为17个菌,为疫苗的制造筛选出了优良的菌株.
