To analysis the sequence variation in the internal transcribed spacer (ITS) rDNA of hookworm isolates from snake in Changsha, the ITS sequences were amplified and the amplicons were cloned into pGEM-T vector for sequencing. The sequence analysis revealed that these ITS sequences were 734 bp in length. The results indicate that these ITS sequences provided to be a useful genetic Marker for identification hookworm species. It was the first time that the ITS sequence of hookworm were reported in our study, which laid the foundation for ...
