| Abstract | Visceral leishmaniasis (VL) is a zoonotic disease caused by the protozoan parasite Leishmania infantum. This parasite is transmitted by sandfly vectors of the genus Lutzomyia, and about 70 species of wild and domestic animals, including dogs have been identified as reservoirs. Brazil remains the most affected among the 13 endemic Latin American countries. In rural and urban slums, social inequalities and poor investments in sanitation contributes to abundance and geographical spread of vectors, as well as increase in cases among humans and reservoir hosts. Dogs remains one of closest companion of human and their role in transmission of zoonotic diseases cannot be overemphasized. In Bahia, the northwestern part of Salvador, over 58% cases of human VL have been reported in the urban areas. Nevertheless, there are limited information on prevalence of indigenous or imported cases among dogs. This information is important to estimate incidence and inform control measures, therefore this study was conducted to estimate the prevalence of VL among dogs from an urban slum in Salvador, Bahia. The study was out between the neighborhoods of Marechal Rondon and Alto do Cabrito, characterized by structural deficit of urban services and recurrent floodings. The extension of the area was communities, an area covering 0.13 km², and with 1,250 households. Canines were recruited through October 2021 and May 2022. Blood samples were collected. by venipuncture in the jugular or cephalic vein, stored in 5ml tubes containing separator gel with clot activator, and centrifuged at 3000 rpm for 15 min to obtain serum. The diagnoses resulted from the rapid immunochromatographic test on double platform (Bio-manguinhos/Fiocruz - in which 5 uL of serum and 4 drops of the kit buffer solution were used, according to the manufacturer's guidelines. A CVL seroprevalence of 10% was recorded from 18 of the 179 tested dogs (95% CI: 5.7 - 14.5), 8/78 were females and 10/80 males. Majority of the dogs (8, 44%) were of indigenous origin, while (4, 22%) were from other neighborhoods (Pirajá, Vila de Abrantes, Pelourinho and Nazaré) and origin of (6, 33%) were unknown. The increase in CVL prevalence may reflect an increase in LV transmission in the urban area of Salvador, coincidently with an increase in VL transmission observed in other areas of Brazil. The increase in cases in urban areas in the country has occurred since 1980 due to several factors, among them, the multiplication of the vector due environmental factors and the intense migration of humans with dogs from rural endemic areas to cities. However, the difference between the prevalence of seropositive dogs in 2022 can also be attributed to the | en_US |
