Kinetes of a Babesia species were found in the haemolymph smears of 5 species of Hyadomma which were detached from trade cattle after engorgement. Hyalomma rufipes had the highest percentage of infection; while this infection rate was significantly higher than those of H. trupcatum and H. impressum, it was statistically similar to those of H. marginatum and H. impeltatum. Studies on the morphology and dimensions of the kinetes show that they are larger than those of B. bigemina, smaller than those of B. major and B. bovis, but similar to those of B. occultans.
