Therefore, the aim of this study was to determine the presence of Anaplasma spp., and Ehrlichia spp. in dogs and ticks in the Thrace Region of Turkey. A total of 400 blood samples and 912 ticks were collected from dogs living in shelters that are located in four cities (Istanbul, Edirne, Tekirdag and Kirklareli) of the Thrace Region. Blood and buffy coat smears were prepared for microscopic examination. Hematologic and serologic analyses were performed using cell counter and commercial Snap3Dx test kit, respectively. Eight hundred fifty of collected ticks were classified as Rhipicephalus sanguineus, 33 as Rhipicephalus turanicus and 29 as Ixodes ricinus. After DNA extraction from blood samples and pooled ticks (127 tick pools, in total), nested PCR was performed to detect the DNA of Anaplasma spp., and Ehrlichia spp. The seroprevalence of Ehrlichia canis was 27.25% (109) by Snap3Dx test and the total molecular positivity was 11.75% (47) in dog blood samples and 21.25% (27) in tick pools by nested PCR. The frequencies of the infected blood samples with E. canis, Anaplasma phagocytophilum and Anaplasma platys were det...
