[A descriptive epidemiological study on canine babesiosis in the Lake Geneva region].

A descriptive study was carried out in the district of the Lake Geneva between March 1, 2005 and August 31,2006 to assess the incidence and prevalence of canine babesiosis, to genotype the Babesia species occurring, to assess the most frequently clinical signs found and to address the potential of autochthonous transmission.
