Abstract

Serological survey of cases of canine visceral leishmaniasis and evaluation of phlebotomine fauna on Marambaia Island, municipality of Mangaratiba, Rio de Janeiro state, Brazil* Levantamento sorológico de casos de leishmaniose visceral canina e avaliação da fauna de flebotomíneos na Ilha da Marambaia,

Fatores ambientais associados à ocorrência de leishmaniose visceral canina em uma área de recente introdução da doença no Estado do Rio de Janeiro, Brasil

“…CVL prevalence in this study (21.65%) was similar to rates in Rio de Janeiro State both in areas of recent introduction (25.2% in Itaipuaçu, Maricá; 18.1% on Ilha de Marambaia, Rio de Janeiro) and in areas classified as endemic (25% in Barra de Guaratiba, Rio de Janeiro) 15,23,24 , notwithstanding differences in methodologies. Prevalence rates can vary due to the diagnostic test used and the way dogs were recruited for the study 25 The geographic expansion of CVL has been recorded in other states of Brazil, attributed to various factors such as difficulties in eliminating reservoirs, epidemiological diversity of the affected regions, high financial costs of sustaining control measures, the vector's high capacity to adapt to the peridomicile, and insufficient control measures 26 .…”
