[Contribution to the knowledge of Swiss piroplasmas]

The authors identify 3 species of Babesia, which parasitize cattle in Switzerland (Babesia major, B. divergens and B. hovis). They also confirm the presence of B. canis in a dog in the proximity of Geneva. Finally, for the first time in Switzerland, they point out the presence of non-identified Babesia in various rodents (Apodemus sylvaticus, A. flavicollis and Clethrionomys glareolus).
