Babesia canis vogeli is a tick-borne protozoan pathogen infecting erythrocytes. In Southeast Asia, this pathogen has only been reported in Thailand. In this study, 9 dogs presented at 3 different veterinary clinics in Cebu City, Philippines were found positive for B. canis vogeli. DNA from blood samples were extracted at the University of Philippines Cebu, and were tested using the Babesia genus screening PCR and B. canis vogeli-specific PCRs (based on the 18S gene) at the National Research Center for Protozoan Diseases, Japan. An amplicon was randomly selected and sequenced for confirmation, and was found to be 100% identical to registered B. canis vogeli sequences. Common findings of the infected dogs include paleness of mucous membrane, inappetence, lethargy, tick infestation, anemia and thrombocytopenia. This is the first report of B. canis vogeli infection in the Philippines.
