Resumen:
Bovine babesiosis represents a serious threat to the cattle industry in the tropics and subtropics. Although several Babesia species infect cattle, only B. bovis, B. bigemina and B. divergens are known to cause clinical babesiosis. However, our recent study demonstrated that the newly discovered Babesia sp. Mymensingh might be a virulent species capable of causing clinical babesiosis in cattle. The objective of this study was to determine the host range and geographical distribution of Babesia sp. Mymensingh on a global scale. A total of 2,860 archived DNA samples from 2,263 cattle in Sri Lanka (n = 672), the Philippines (n = 408), Vietnam (n = 460), Uganda (n = 409), Brazil (n = 164) and A rgentina (n = 150); 419 b uffalo in S ri L anka (n = 327) and Vietnam (n = 92); and 127 goats and 51 sheep in Vietnam were screened using a Babesia sp.Mymensingh-specific PCR assay. Babesia sp. Mymensingh infection was detected incattle, buffalo, sheep and goats. Cattle of all countries surveyed in this study except Brazil were found to be infected with Babesia sp. Mymensingh. The highest positive rates were recorded in cattle from the Philippines (11.3%) and Vietnam (9.6%), followed by Argentina (4.7%), Sri Lanka (1.5%) and Uganda (1.0%). Buffalo were found to be infected with this parasite in Sri Lanka (1.2%) and Vietnam (10.9%). Unexpectedly, Babesia sp. Mymensingh was also detected in sheep (2.0%) and goats (1.3%) from Vietnam. These findings were confirmed by PCR amplicon sequencing
