摘要
为掌握春季猪瘟集中免疫效果,于2009年4月随机采集了隆安县部分猪血清,以正向间接血凝方法(HA)检测猪瘟免疫抗体,结果表明,隆安县各乡镇散养猪的猪瘟免疫抗体水平不均衡,免疫效果差距明显,而规模猪场依然存在疫情隐患;猪瘟免疫抗体效价分布出现2个极端,抗体效价≤1∶2的占26.8%,1∶256的占25.1%,整体免疫效果较差。并通过分析免疫质量不佳的原因,对今后提高猪瘟免疫抗体水平的应对措施进行探讨,为有效防制猪瘟发生与流行提供参考。
The immunological effects of classical swine fever vaccine have been investigated during the spring season. Serum samples from pigs in Long＇ an County were collected randomly in April, 2009, and the classical swine fever antibody was detected in serum samples by indirect hemagglutination （HA） method. The results differed significantly in antibody levels and immunological responses in pigs from different townships and towns. The risk of classical swine fever still existed in intensive pig farms. The classical swine fever antibody levels distributed in two extremes and the percentage of pigs in which antibody titer was lower than 1：2 and 1：256 were 26.8% and 25.1%, respectively. The immune effect of the whole pigs was relatively worse. Further, the reasons for the poor quality of immunization have been analyzed and the for improving the antibody levels were discussed to provide the reference for effective prevention and control of the occurrence and epidemics of classical swine fever.
