University of Tehran Press Journal of Veterinary Research 2008-2525 65 1 2010 03 21 IDENTIFICATION OF SARCOCYSTIS GIGANTEA BY PCR- RFLP IDENTIFICATION OF SARCOCYSTIS GIGANTEA BY PCR- RFLP 43 46 20424 FA Abdolhossein Dalimi Fatemeh Jalosian Frid Tahvildar Biderouni Fatemeh Gaffarifar Journal Article 1970 01 01 Sarcocyst is one of the most important protozoa belonged to apicomplexa. This parasite is prevalent among warm blooded animals throughout the world. In the present work, Sarcocystis gigantea was identified by amplification of 18S rRNA gene using PCR- RFLP. In this regard macroscopic cysts of sarcocystis were collected from esophagus and intra costal muscles of sheep in Shahriar slaughterhouse. Then genomic DNA of the parasites was extracted from specimens using phenolchloroform method. 18S rRNA gene was amplified with specific primers. For RFLP two restricted enzymes of MspI and MobI were used and the patterns were analyzed accordingly. According to the resulted band, all the specimens were identified as Sarcocystis gigantea. This is the first report of molecular identification of Sacrocystis gigantea in Iran. Sarcocyst is one of the most important protozoa belonged to apicomplexa.
