[Babesia infections in horses, cattle and dogs in southern Germany].

Babesia infections serologically diagnosed in horses, cattle and dogs in Southern Germany during the last few years are described. 321 sera of horses were examined for specific antibodies to Babesia by means of CFT and IIF in 1984; 18 sera reacted to Babesia equi and 4 to Babesia caballi antigen. In a cattle breeding area in the Western Allgäu 13% of 1616 cattle reacted positive to Babesia divergens antigen using IIF and ELISA; during the grazing season 1982 new latent infections were observed in 25 of 266 calves and heifers. Cases of introduced canine babesiosis are more frequent; 10 of 34 sera of dogs in 1983 and 34 of 75 sera in 1984 had specific positive reactions to Babesia canis by means of IIF.
