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 leishmaniasis was firstly recognized in Brazil during the 1930s [27]. This disease is mainly caused by Leishmania infantum (Kinetoplastida: Trypanosomatidae) (Fig. 3), sometimes referred to as Leishmania chagasi or Leishmania infantum chagasi [28]. Infection by other Leishmania species (e.g., Leishmania amazonensis) have also been reported [7,10] and cases of co-infection by two species (e.g., L. infantum and Leishmania braziliensis) as well [29]. The main vector of L. infantum in Brazil is Lutzomyia longipalpis (Diptera: Psychodidae). Other modes of transmission, including by Rh. sanguineus ticks, are suspected to occur [30,31], particularly in foci where suitable phlebotomine sand fly vectors are absent (e.g., Recife, Northeast Brazil) [32]. The vectors of L. amazonensis and L. braziliensis vary from region to region and several species may eventually be involved, including Lutzomyia whitmani (Fig. 4) and Lutzomyia intermedia (reviewed in [33]).
