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 Rocky Mountain spotted fever is caused by Rickettsia rickettsii (Fig. 11) and has been associated with significant morbidity and occasional mortality in the United States [147,148]. Serological surveys conducted in Brazil have shown that dogs from some Rocky Mountain spotted fever-endemic areas (e.g., Minas Gerais and São Paulo) are exposed to R. rickettsii infection [129,149-154]. The vectors of R. rickettsii are Amblyomma ticks, mainly Am. cajennense [155] (Fig. 12) and Am. aureolatum [156]. Additionally, Rh. sanguineus ticks have the potential to be involved in the R. rickettsii transmission cycle in areas other than Mexico and United States, including Brazil [157]. Serological surveys in Minas Gerais, Espírito Santo, Rondônia, and São Paulo revealed that the prevalence of anti-R. rickettsii antibodies in dogs ranges from 4.1 to 64% [129,149-154,158]. However, it is difficult to estimate the actual prevalence of R. rickettsii infection in dogs using serological tests, because of their low specificity [157].
