摘要
采用PCR-RFLP法检测了湖南境内大白、长白、杜洛克3品种共158头猪的E.coliF18受体基因型。结果表明,抗性基因型AA的频率为0.11,敏感型AG、GG的频率分别为0.35和0.54。
A total of 158 pigs of Yorkshire,Landrace and Duroc were selected from some swine breeding farms in Hunan province.The genotypes of enterotoxigenic E.coli F18 receptor were tested by PCR-RFLP.The results showed that the frequency of resistant genotype AA was 0.11,the frequencies of susceptibility genotype AG and GG were 0.35 and 0.54 respectively.
