In this study, the classification of Chinese Babesia spp. infective to cattle were carried out by the classical methods and molecular biotechnology, and investigated the vector ticks of an unidentified Babesia sp. isolated from Xinjiang province by the experimental transmission, and observed the developmental forms of Babesia sp. in the engorged Hyalomma anatolicum anatolicum females;We developed the indirect hemoagglutination test for Babesia bigemina, and evaluated its effect in the sero-survey;We made slow-released injection of imidocarb, and estimated its efficacy on the treatment and prevention of Babesia bigemina infection by the laboratory work and the field tests. The major results were presented as following:1. Discovery of a bovine Babesia sp.
