Babesia gibsoni infection in dogs in Poland.

Canine babesiosis is a tickborne, protozoal, haemoparasitic disease. Babesia organisms are frequently classified as either large (B. canis) or small (B. gibsoni). The aim of this study was an attempt to detect B. gibsoni DNA in blood samples taken from dogs suspected of suffering from tick-borne diseases. 216 samples were tested using PCR, of which, in 99 of them B. canisDNA was detected, whereas in 3 of them B. gibsoni was detected. Positive PCR results for B. gibsoni were confirmed using a Qube MDx real-time analyzer. The results indicate that infec-tions with this B. gibsoni should be taken into account and included in the differential diagnosis of vector-borne diseases in dogs in Poland, and that the accurate identification of the species of parasite causing the infection is crucial for developing the correct treatment regimen and prognosis.
