摘要
采用H5N2和H5N1两种类型的禽流感(A I)油乳灭活疫苗免疫鸡群对高致病性A I流行株H5N1A IV的攻毒保护效力进行了比较。结果表明:在同等免疫剂量条件下,H5N2和H5N1油乳灭活苗对鸡群具有相似或同等的免疫效力,均能抵抗对高致病性A IH5N1流行株的攻击;A I母源抗体对灭活苗免疫具有一定的干扰作用。
In this study, protective efficacy of commercial chickens at 14-day-old immunized with H5N2 and H5N1 subtype inactived oil-emulsion vaccine to the challenge of H5N1 AIV was evaluated. The results showed that the protective effects of flocks immunized with H5N1 and H5N2 was similar and presence of maternal antibody could interfere with chicken＇s active immunization.
