This experiment was carried out to attain prevalence and molecular characterization of pathogens causing canine vector-borne diseases (CVBDs) including babesiosis, hepatozoonosis, leishmaniasis, filariosis (Dirofilaria immitis, Dirofilaria repens, and Acanthocheilonema reconditum), ehrlichiosis (Ehrlichia canis), and anaplasmosis (Anaplasma platys) in stray dogs. The study material consisted of 133 asymptomatic female (n = 96) and male (n = 37) stray dogs (≤1 year old, n = 16 and 1-6 years old, n = 117) housed in the Animal Care and Rehabilitation Center, Erzurum, Northeastern Turkey. Conventional and nested PCR were performed on blood samples to detect Babesia spp., Leishmania spp., Hepatozoon spp., D. immitis, D. repens, A. reconditum, E. canis, and A. platys. Sex and age association with the pathogen prevalence was determined using X2 statistics. The positivity rate for at least one CVBD pathogen was 48.9% (65/133). DNA of B. canis, Hepatozoon spp., H. canis, D. immitis, and E. canis were detected in 5.3% (7/133), 27.1% (36/133), 5.3% (7/133), 1.5% (2/133), and 9.8% (13/133) of the dogs, respectively. Leishmania spp., D. repens, A. reconditum, and A. platys DNA were not detected. Mixed pathogens were determined in seven (10.8%) of the infected dogs, with predominant involvement of Hepatozoon spp. or H. canis. The pathogen prevalence did not vary by sex or age. Nucleotide blast analysis of Erzurum isolates showed 99.8-100% identities with the corresponding reference isolates. This study indicates presence of five CVB pathogens, including the first report of E. canis, in stray dogs in Erzurum, Turkey.
