The Genetic Variation of Two Microsatellite Markers of Escherichia coli F4(K88) Receptor in Different Swine Breeds
不同猪种肠毒素大肠杆菌（ETEC）F4受体微卫星标记遗传差异性研究The Genetic Variation of Two Microsatellite Markers of Escherichia coli F4(K88) Receptor in Different Swine Breeds

The genetic variation of ETEC F4 receptor in Shaziling and Yorkshire breeds were studied using two microsatellite markers(S0223 and S0068). The results showed that there were polymorphisms in the two markers, and there were great variations of the gene heterozygosity and Shannon information index in the two breeds. It was also reported that there were differences in K88ab and K88ac receptors in Chinese native breeds and foreign breeds, so the two markers might be the genetic markers of F4 receptor gene.
