ABSTRACT
PURPOSE:
Piroplasmosis is responsible for anemia, fever, loss of physical activity and even death in equines. In epidemiological studies, accurate diagnostic tests are essential for detecting asymptomatic carriers. This study aimed to investigate the prevalence of infection in asymptomatic horses from Lorestan province, western Iran by developing a multiplex PCR. METHODS ANDRESULTS:
Blood samples were examined by microscopy and multiplex PCR targeting the SSU rRNA gene of Theileria equi and Babesia caballi. Out of the total of 165 horses, 19 (11.51%) and 31 (18.78%) cases were positive for piroplasms by microscopy and PCR, respectively. The detection rates of both genera were significantly higher in multiplex PCR compared to microscopy (p < 0.0001). Compared with multiplex PCR, the sensitivities of microscopy for the detection of Babesia were only 28.5%. The prevalence of T. equi infection was significantly higher in summer (p = 0.035). The prevalence of B. caballi was significantly higher in males (p = 0.038).CONCLUSION:
Findings indicate that the multiplex PCR described here is a sensitive technique for the detection of piroplasm DNA in carriers. Furthermore, asymptomatic carriers must be considered as an important source of infection for equids living in this region.Palabras clave
