Abstract excerpt
The virulence phenotype of Babesia bovis subpopulations was evaluated using biological clones derived from the high-virulence BboS2P and the low-virulence BboR1A strain and two original virulent isolates, BboL15 and BboL17, multiplied extensively in vitro or attenuated by successive passages in splenectomized calves. The virulence phenotype was assessed both by inoculation of normal Holstein adult steers and by...
