[Canine visceral leishmaniasis in northeast Brazil: epidemiological aspects]

Abstract

In a rural area of Northeast Brazil, the relatively high serological infection by Leishmania in dogs, the lack of classical vector Lutzomyia longipalpis and of American Visceral Leishmaniasis cases in human beings and the observation of Leishmania in ticks collected in infected dogs suggest that ticks may be responsible for the transmission between dogs.
