Identify of Sarcocytis hominis in cattle carcasses using PCR method

A survey was carried out to investigate the occurrence of Sarcocystis spp. and identification of Sarcocystis hominis slaughtered cattle's in Isfahan slaughterhouse. In all, the muscle tissue (cardiac and diaphragmatic muscles) of 768 samples from 384 cattle carcasses were examined by microscopic method. Based on the microscopic examination the prevalence rate of Sarcocystis cysts in the cattle's were 62.8%. Based on the PCR method, 207 sample from 431 infected samples (48.1%), were positive for Sarcocystis hominis. Not significant difference was observed between the prevalence in cardiac and diaphragmatic muscles (P>0.05). The results indicated that Sarcocytsis cysts in the Isfahan is consumption of under–cooked cattle meat may result in Sarcocytsis in humans.
