| Abstract: | Objective] The aim was to establish a molecular biological method for identifying coccidium species.Method] First,the pure species of Eimeria intestinalis was isolated by using single-oocyst isolation technique,and oocyst genome DNA was extracted.Then,according to the 18s rDNA and 5.8s rDNA sequences of Eimeria Coccidia published in GenBank,a pair of specific primers were designed and synthesized to amplify the internal transcribed spacer 1(ITS-1).Finally,the PCR products were sent for sequencing.Result]... |
