摘要
对鸭瘟、鸭霍乱紧急防治措施作了系列研究,结果表明:鸭瘟、鸭霍乱多价卵黄抗体对100个LD50鸭瘟强毒和8.3个C48-1强毒菌的攻击具有100%(8/8只)中和能力,对鸭瘟强毒(100个LD50)和C48-1(8.3个)攻毒后5~6小时注射4倍稀释卵黄抗体2.0ml/只,具有100%(6/6只)保护(口服有83.3%保护);分别以正常量和5倍量的鸭瘟弱毒苗免疫2月龄鸭,5~6小时后攻鸭瘟强毒,结果无一存活,鸭瘟弱毒苗和鸭瘟-禽霍乱二联活苗免疫后3天,对100个LD50鸭瘟强毒攻击获50%(3/6)保护,7天获83.3%(5/6)保护。A群菌苗免疫后6天对C48-1攻击获66.7%(4/6只)保护,12天获100%保护。鸭瘟-禽霍乱二联活苗免疫后3天对C48-1攻击获33.3%(2/6)保护,7天获83.3%保护;巴氏杆菌卵黄抗体和血清抗体能明显抑制巴氏杆菌生长并有溶菌现象出现;复方痢菌净、喹乙醇、庆大霉素、链霉素和四环素对多杀巴氏杆菌高度敏感(17~41mm)。
At present studies,the emergency prevention measures of Duck plague and Duck Cholera were covered Results showed 1)Polybasic yolk antibodies Duck Plague and Cholera pathogens have 100%(8/8)resistance for the antitacking of F 33 100 LD 50 and C 48-1 (8 3)5 to 6 hrs after antitacked with F 33 100 LD 50 and 8 3C 48-1 ,Ducks injected (4 times dilute)yolk antibody have 100%(6/6)defense rate 2)Immuned with Duck Plague vaccines 1to 5 times for 5 6hrs the ducks have no resistance for attacking of 100 LD 50 F 33 Injected with G 190 Е 40 vaccines 3ds,the ducks got 50%(3/6)defense rate for attacking 100 LD 50 F 33 ,and 7ds,got 83 3%(5/6).Whereas Pasteurella Mulitocida Vaccines A was immuned to duck 6ds, 66 7% defense rate was got to C 48-1 attacking,G 190 E 40 Vaccines was injected to duck,33 3%(2/6)defense rate would be got to C 48-1 antitacking in 3ds and 83 3% in 7ds,respectiving 3)Yolk and serum antibodies to Pasteurella Multocida have obviously inhabited the growth of Pasteurella Mulitocida and 4)5 kinds of antibodies have highly susceptible(17 41mm)to Pasteurella Mulitocida
