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 heartworm was firstly recognized in Brazil in 1878 [3]. The disease is caused by Dirofilaria immitis (Nematoda: Onchocercidae), which is transmitted by many mosquito species. Aedes scapularis and Aedes taeniorhynchus are implicated as the primary vectors, while Culex quinquefasciatus is a secondary vector [170-174]. Another filarid nematode commonly found infecting dogs in Brazil is Acanthocheilonema reconditum (formerly Dipetalonema reconditum) (Nematoda: Onchocercidae), whose intermediate hosts are fleas (Ctenocephalides canis and Ctenocephalides felis) (Fig. 13) and lice (Heterodoxus spiniger and Trichodectes canis) [175,176]. Acanthocheilonema reconditum infection usually causes no clinical signs in dogs. Despite this, it is important to distinguish the microfilaria of A. reconditum from that of D. immitis, as these filarid nematodes are often found in sympatry.
