[Dogs babesiosis--still actually problem].

Babesiosis (piroplasmosis) is a tick-borne disease with a symptoms of hemolytic anemia. For the first time babesiosis was described in dogs in United States in 1934. The etiological factor of this disease in Poland is protozoa Babesia canis, and its vector--Dermacentor-tick. The most common symptoms of babesiosis are: icterus, hemoglobinuria, occasionally vomits and diarrhea. The biochemical examination of blood serum from sick animals can reveal the increase of activity of AST, ALT, the increase of total bilirubine, urea and creatynine concentrations. The results of hematological examinations can show anemia, leucopenia and thrombocytopenia. The diagnosis of babesiosis bases on anamnesis, clinical examinations of dogs, microscopical examinations of blood smears from sick animals; IF-assay and PCR can also be helpful for the diagnosis of babesiosis. Till now does not exist the effective immunoprophylaxis against this disease. Babesiosis is well-known disease, however there are still problems with therapy of infected animals. Most effective drug in therapy of dog piroplasmosis is imidocarb, but sometimes can be observed side effects after it application. It is possible that the genetically differences which are detected in subspecies may have an influence on the severity of disease and the effectiveness of therapy.
