| Abstract: | To establish a molecular biological method for identifying coccidium species,a pair of specific primers was designed according to previously published sequences of 18S rDNA and 5.8S rDNA of Eimeria coccidia in the GenBank database.The pure species of Eimeria flavescens was isolated using single-oocyst isolating technique and the gene of ITS-1 of E.flavescens was amplified by PCR assay.The PCR product was cloned and sequenced,which showed that the pure species of E.flavescens was successfully isolated and the gene fragment including ITS-1 of E.flavescens was 455bp long. |
