Seroprevalence and risk factors associated with visceral leishmaniasis in dogs in Jaciara, State of Mato Grosso

Abstract

Introduction: Visceral leishmaniasis is a neglected disease. Jaciara, State of Mato Grosso has the most cases. This study aimed to determine the risk factors and seroprevalence of canine visceral leishmaniasis in urban and rural areas. Methods: This cross-sectional study of domestic dogs used enzyme-linked immunosorbent assay and indirect immunofl uorescence test. Results: The prevalence was 54.7% among 345 analyzed samples. Short coat, age of 1-6 years, and living less than 100m from vegetation posed the highest infection risks. Conclusions: Certain dog behaviors and characteristics, and their correlation with environmental conditions, were relevant in the high prevalence of canine leishmaniasis in Jaciara.

Uso e cobertura do solo e prevalência de leishmaniose visceral canina em Teresina, Piauí, Brasil: uma abordagem utilizando sensoriamento remoto orbital

“…This result is consistent with other studies that have pointed to higher canine seropositivity for Leishmania in dwellings close to forest areas 21,22,23,24,25,26 . The proximity to areas with more dense vegetation favors interaction between the sylvatic and peridomiciliary cycles of the disease and favors conditions for maintenance of sand fly populations 2 .…”

Leishmania chagasi in dogs from the city of Jaciara, Mato Grosso, Brazil

“…Several regions in Brazil are endemic for CVL, with Jaciara being one of the cities with the highest serological prevalence in Mato Grosso (BRITO et al, 2014a;LOPES et al, 2014). The observation that 96.04% of PCR positives were associated with seropositive dogs confirms the occurrence of the infection, despite of the possibility of cross-reactivity in serological tests as recommended by the Ministry of Health (BRAZIL, 2006;MADEIRA et al, 2009).…”

“…The municipality of Jaciara has presented VL cases since 2003 with a prevalence of 54.7% CVL (BRITO et al, 2014a;2014b;LOPES et al, 2014) species in dogs. In this context, the aim of this study was to identify the Leishmania species in domestic dogs in the urban Jaciara area by PCR and to evaluate the use of this diagnostic technique in different tissues.…”

“…Habitat is considered an important environmental factor in the epidemiology of leishmaniasis, mainly due to the presences of organic debris or forests close to human habitations, which can facilitate the maintenance of the vector and the occurrence of the disease (BRANDÃO-FILHO et al, 1994;MORENO et al, 2005;BIGELI et al, 2012;LOPES et al, 2014). In addition, there were more samples from rural areas than from urban areas, which may have influenced the findings of our serosurvey.…”
