Canine vector-borne diseases in Brazil.

Dantas-Torres F - Parasit Vectors (2008)

Bottom Line: Canine vector-borne diseases (CVBDs) are highly prevalent in Brazil and represent a challenge to veterinarians and public health workers, since some diseases are of great zoonotic potential.Dogs are affected by many protozoa (e.g., Babesia vogeli, Leishmania infantum, and Trypanosoma cruzi), bacteria (e.g., Anaplasma platys and Ehrlichia canis), and helminths (e.g., Dirofilaria immitis and Dipylidium caninum) that are transmitted by a diverse range of arthropod vectors, including ticks, fleas, lice, triatomines, mosquitoes, tabanids, and phlebotomine sand flies.This article focuses on several aspects (etiology, transmission, distribution, prevalence, risk factors, diagnosis, control, prevention, and public health significance) of CVBDs in Brazil and discusses research gaps to be addressed in future studies.

Mentions: Canine monocytic ehrlichiosis was firstly recognized in Brazil in the 1970s [122]. This disease is caused by Ehrlichia canis (Rickettsiales: Anaplasmataceae) (Fig. 10), which was firstly isolated in Brazil in 2002 [123]. The agent of canine monocytic ehrlichiosis is well characterized in Brazil [124-128], where it is transmitted by Rh. sanguineus [124]. Other Ehrlichia species found in Brazil – e.g., Ehrlichia chaffeensis; [129] – are also suspected to infect dogs. In fact, there is serological evidence of E. chaffeensis infection in Brazilian dogs [130].
