Abstract

BORGES, Luiz Felipe Nunes Menezes et al. Prevalence and spatial distribution of visceral leishmaniasis in dogs Juatuba, Minas Gerais, Brazil. Cienc. Rural [online]. 2014, vol.44, n.2, pp.352-357. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782014000200025.

The objective of the present study was to determine the prevalence and spatial distribution of visceral leishmaniasis in dogs (VLD) at Juatuba city, Minas Gerais, Brazil, in 2010. A cross-sectional observational study was performed collecting blood samples from 957 dogs, defined randomly in all city districts. For the sorological diagnosis was used indirect immunofluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA), recommended by the Ministry of Health. Geographical coordinates of properties that participated in the survey were marked in order to check the spatial distribution of canine cases. The VLD prevalence was estimated in 10.6%, ranging from 3% to 50.0%, distributed between 70.6% of city districts. Spatial distribution could be observed by scanning the clusters and according to the disease occurrences the demarcation of different risk areas could be obtained. There was an increase of 2.80 times more likely to acquire the VLD on the primary cluster. As of this research the prevention and control actions for VLD were made according to the specificity of each location to prevent the disease spread among dogs and new human cases.
