Abstract
Among the infections caused by arthropods in dogs are Leishmania infantum, Babesia canis and rickettsias Ehrlichia canis and Anaplasma phagocytophilum. Studies show, in Brazil, high rates of co-infection in dogs by these agents. In Carmo da Mata, Central West of Minas Gerais there are no reports of cases of human or canine visceral leishmaniasis (CVL). In this municipality, the existence and prevalence of LVC and concomitant seropositivity with B. canis and rickettsias were evaluated. In the urban area, 433 domiciled dogs were tested for Leishmania infection, with three immunological tests (rapid immunochromatography and ELISA), with a prevalence of 0.7% (95% CI: 0.2-1.9). To evaluate the concomitant seropositivity, 433 dogs were evaluated by indirect immunofluorescence reaction, with 166 (38.3%) reagents for A. phagocytophilum, 171 (39.5%) for B. canis and 231 (53.3%) for E. canis. Of the total, 192 (44.2%) presented concomitant seropositivity with the three agents. Of the three dogs with CVL, one had only CVL and two had concomitant seropositivity, one with B. canis and the third with A. phagocytophilum and E. canis. Immunosuppression caused to dogs by ehrlichiosis can lead to an increase in cases of LVC and thus, it is necessary preventive measures to avoid the expansion of LVC in the municipality.
Highlights
Leishmaniasis are part of a group of diseases with different clinical and epidemiological characteristics, which are considered neglected by the World Health Organization (World Health Organization, 2018)
The presence of Lutzomyia longipalpis phlebotomine sandflies was detected in the municipality of Carmo da Mata, located in the central west region of Minas Gerais, but there are no reports of human VL (HVL) cases and no epidemiological studies on canine Visceral leishmaniasis (VL) (CVL) (Minas Gerais, 2016)
According to the PC-VL recommendations, only the dogs considered positive in the TR-DPP and ELISA were considered positive for CVL
Summary
Leishmaniasis are part of a group of diseases with different clinical and epidemiological characteristics, which are considered neglected by the World Health Organization (World Health Organization, 2018). The presence of Lutzomyia longipalpis phlebotomine sandflies was detected in the municipality of Carmo da Mata, located in the central west region of Minas Gerais, but there are no reports of HVL cases and no epidemiological studies on canine VL (CVL) (Minas Gerais, 2016). According to the Visceral Leishmaniasis Control Program Manual (PC-VL) of the Brazilian Ministry of Health (MS), these characteristics define the city as a silent and receptive area for VL transmission (Brasil, 2014b). Control strategies proposed by the MS include canine reservoirs, insecticide application, and diagnosis and early treatment of human cases. These actions should be executed together for better effectiveness (Brasil, 2014b)
