Abstract

    Equine theileriosis is one of the most important parasitic diseases among the equids that poses a serious threat to the horse industry. Proper diagnosis of parasites in carriers is important for prevention and effective control measures. Therefore, the aim of the present study was to investigate the probable presence of Theileria equi infection in dogs from Ahvaz city. A total of 100 blood samples from dogs were examined for the presence of T. equi infection using molecular methods. After DNA extraction from the dog's whole blood, for tracking DNA of T. equi polymerase chain reaction was performed and the results were observed in agarose gel. Out of 100 samples, the PCR method detected T. equi infection in two dogs. In other words, two percent of dogs were probably carriers for T. equi. In conclusion, the present study revealed that dogs from Ahvaz city are infected with T. equi. So these animals can be probably considered as the carriers of T. equi. Therefore, we should pay attention to dog's with T. equi infection in equine theileriosis control programs.
