Dogs can carry and share zoonotic pathogens with humans. This problem is understudied in different parts of the world, including Jordan. This study determined the prevalence of Anaplasma phagocytophilum, Ehrlichia canis, Dirofilaria immitis, and Borrelia burgdorferi using the SNAP 4Dx Plus test and spotted fever group rickettsiae (SFGR) using enzyme immunoassay IgG test in different types of dogs (farm/breeding, police, and stray) in Jordan. The results showed a very high seroprevalence (87%) of SFGR in dogs all over Jordan. Specifically, the seroprevalence was 97.0, 90.5 and 71.2% in farm, stray, and police dogs, respectively. Overall, 9.9% of dogs were seropositive for A. phagocytophilum. Specifically, 14.9% of farm, 14.3% of stray, and 0% of police dogs were seropositive. None of the studied dogs had D. immitis, E. canis, or B. burgdorferi. It can be concluded that SFGR and A. phagocytophilum are endemic in Jordan. This study suggests that controlling stray dogs and monitoring dog breeding farms should be considered as control measures to limit the transmission of SFGR and A. phagocytophilum and to limit their public health impact in Jordan. Moreover, further follow-up studies are needed to study these pathogens in the human population in Jordan.
