Ehrlichia ewingii, Anaplasma phogocytophilum and hemotropic Mycoplasma spp. are three bacteria which can infect different dog’s blood cells. All of these three pathogens can be transmitted by different ticks and some reservoir hosts also play a role in their transmission. Although E. ewingii and A. phagocytophilum infect granulocytes and neutrophils of their hosts, respectively, hemotropic Mycoplasma spp. can infect reticulocytes. In this research, the previously taken dogs’ blood films were collected randomly from different veterinary hospitals of Tehran, the capital of Iran. The blood films were reinvestigated for arthropod-borne diseases. Surprisingly, E. ewingii/A. phagocytophilum morulae and hemotropic Mycoplasma spp. were observed in 18% and 37.7% of samples, respectively. None of these pathogens have been reported in Iran. In addition to the new report, the changes which have been made by these pathogens, their similarities, differences and zoonotic importance are discussed.
