【 摘 要 】

Serum and DNA from blood samples collected from Vietnamese yellow cattle (n=101) andcattle imported from Thailand (n=54) at a Vietnamese slaughter house were screened forBabesia bovis and Babesia bigemina infections byenzyme-linked immunosorbent assay (ELISA) and PCR. The positive rates determined by ELISA(B. bovis and B.bigemina) or PCR (B. bigemina) in theVietnamese cattle were significantly higher than those found in Thai cattle. SomePCR-positive Vietnamese animals were ELISA-negative, whereas all PCR-positive Thai cattlewere ELISA-positive, suggesting that the animals were infected in Thailand. ImportingBabesia-infected cattle may lead to the introduction of new parasitestrains, possibly compromising the development of anti-Babesia immunecontrol strategies in Vietnam.
