Survey of Theileria Parasite Infection in Cattle in Cambodia and Vietnam Using Piroplasm Surface Protein Gene-Specific Polymerase Chain Reaction

Abstract

A survey of Theileria parasite infection in cattle in Cambodia and Vietnam was carried out by using allele-specific polymerase chain reaction. A total of 137 blood samples from draught animals in Cambodia and 40 blood samples from dairy cattle in Vietnam were analyzed. In Cambodia, 69 out of 137(50.4%) samples were PCR-positive containing mainly the Thai and the C type parasites. In Vietnam, 11(27.5%) samples were positive and all were of the Thai type parasite.
