Visceral leishmaniasis in dogs from rural settlements

ABSTRACT:

In rural settlements there are higher concentrations of reservoirs and vectors of canine visceral leishmaniasis (CVL) due to environmental changes resulting from human action by occupation of the territory, however, there are no surveys in Brazil on epidemiological information of CVL in these areas. The aim of this study was to determine the seroprevalence of Leishmania sp. in dogs from rural settlements, as well as to identify the risk factors associated with infection. A total of 306 dogs were tested, and the serological diagnosis of CVL was performed by ELISA S7. Of the 306 dogs, 118 presented anti-Leishmania sp. antibodies., resulting in a frequency of 38.6%. The risk factors identified for CVL seropositivity were: age of 12-24 months (OR=2.97), age of 24-48 months (OR=4.83), age of 4-6 years (OR=4.40), age >6 years (OR=3.62), contact with poultry (OR=1.67) and gender (female) (OR=1.97). Dogs from rural settlements in the semiarid of Paraiba showed high anti-Leishmania sp. antibody frequency, what makes the population of those settlements susceptible to infection. This highlights for the need to alert the epidemiological surveillance agencies to stablish prevention and control methods for that zoonosis, including educational and health activities on these settlements, as they are located in areas with favorable characteristics for CVL installation.
