Abstract :
Cysticercus bovis is a neonatal stage of stenosis called Taenia saginata. Laboratory diagnosis is based on the appearance of the parasite and the microscopic examination of the pathology. Misdiagnosis occurs when other parasites, such as Sarcocystis, are present or when the parasite is metamorphosed and calcified. Therefore, more accurate tests are necessary to diagnose the parasite. In this study, observational and cross-sectional analysis and diagnosis were performed using PCR and primer method based on mitochondrial cytochrome c oxidase gene. To investigate the occurrence of cows infected with Cysticercus bovis in Isfahan and Shahrekord, 384 samples of thigh and heart muscle tissues of cows slaughtered in Isfahan and Shahrekord slaughterhouses were tested for Cysticercus bovis infection by molecular methods. Based on the tests performed, 3.64% of the samples were infected with Cysticercus bovis. The results of this study showed that infection of bovine carcasses with Cysticercus bovis is significant and this could increase the incidence of adult worms in the human population.
