The PCR method was compared with fluorescent antibody test(IFAT) in order to evaluate the diagnosis effciency for B. caball infection in horses. Of 142 field samples from Mongolia, 28(20%) and 96(69%)samples were identified positively by PCR and IFAT, respectively. Although the sensitivity of PCR was lower than IFAT, it was noted that the 5 IFAT-negative samples were PCR-positive, suggesting that the combination of PCR method and IFAT for diagnosis of B. caballi infection may be effective in detecting the carrier horses.}, pages = {85--89}, title = {Diagnosis of Babesia caballi Infection in Horses by Polymerase Chain Reaction}, volume = {8}, year = {1998} }
