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. canis DNA 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 infections 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.

The aim of this study was to analyze cases of granulocytic anaplosmosis diagnosed in 53 hunting dogs in Poland. Medical records of dogs naturally infected with Anaplasma phagocytophilum were retrospectively evaluated with regard to clinical signs and laboratory abnormalities at the time of presentation, therapy and course of disease. The most common clinical signs in A. phagocytophilum-positive dogs included in the study were lethargy (100%), inappetence (94%) and fever (92.5%). Thrombocytopenia was the most common laboratory abnormality (100%), followed by a drop in haematocrit level (79.3%) and increased AST activity (75.5%).
Of the 53 infected dogs, 51 (96%) recovered and two dogs (with neurological symptoms) died.
Analysis of these cases indicates that A. phagocytophilum infection must be considered in differential diagnosis in dogs living in Poland, especially in hunting dogs with thrombocyto- penia and Ixodes ricinus tick invasions.
