Results of PCR for five positive samples. Screening by PCR produced a 645-bp fragment for Babesia (lanes Bc, 44, and 55) and a 780-bp fragment for Hepatozoon (lanes Hc, 8, and 15). Isolate 78 showed dual positivity for Babesia and Hepatozoon, with 645- and 780-bp fragments. Lane M, molecular size marker; lane N, negative control.
