The geographical distribution of vector-borne diseases is influenced by a complex dynamic of environmental and social factors and by the changing impact of transmission of their vectors and intermediate hosts and reservoirs. The objective of the present study was to evaluate the seropositivity for antibodies anti-Ehrlichia canis, Anaplasma phagocytophilum y Borrelia burgdorferia, and the seropositivity to antigens of Dirofilaria immitis in dogs in an area of Mexico with a cool climate. 100 blood samples from dogs were took in private homes and at veterinary clinics in the State of Amecameca de Juárez, Mexico State. The analysis of samples was carried out by a commercial ELISA kit (Test SNAP® 4Dx® Plus Canine IDEXX®). There was a seropositivity for antibodies anti-E. canis of 30 %, 9 % for A. phagocytophilum, 4 % for B. burgdorferi and 16 % for D. immitis antigen. Likewise, it was found a statistically significant relationship between anti-E. canis antibodies and the seropositivity in dogs older than one year of age and purebred. In addition, it was reported similar results in male dogs and older than a year with seropositivity to D. immitis. With the results obtained, it is concluded that there is higher seropositivity for infection by E. canis and D. immitis, and a significant association in dogs older than one year. It is great relevance to know the epidemiology of pathogens transmitted by ticks due to the zoonotic impact involved. Additional research is recommended, as well as preventive measures of animal health and public heath to reduce the risk of infection in dogs.
