Abstract: Barra de Guaratiba is a coastal area of the city of Rio de Janeiro where American visceral leishmaniasis (AVL) is endemic. Although control measures including killing of dogs and use of insecticides have been applied at this locality, the canine seroprevalence remains at 25% and during 1995 and 1997 eight autochthonous human cases were notified. In order to evaluate factors related to the increase of the risk for Leishmania (Leishmania) chagasi infection in dogs we have screened 365 dogs by anti-Leishmania imm… Show more

“…There was no association between L. infantum infection and the dog's sex, age, or degree of confinement, corroborating other studies 24,34,35,36,37 . The household's proximity to forest areas also failed to show an association with L. infantum infection.…”

“…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 .…”

“…The failure of dog culling to reduce the number of human cases in Brazil has been suggested to indicate the existence of other reservoirs, but this failure can be readily explained by logistical and dog demographic factors (see below). Risk factor studies can suggest sylvatic reservoirs, such as the association between human infection and opossums in a Brazilian study (Cabrera et al 2003), but ruling out other confounding factors is essential. Spatial scale is also important for risk factor studies since the vector is mobile : there is often no association between human infection and dog ownership at the household level, whereas such an association is more likely observed at the village level, as demonstrated in Iran (Mazloumi Gavgani et al 2002 b).…”

“…Souza e cols 12 detectaram Lutzomyia intermedia em Inoã, no entanto, L. longipalpis ainda não foi descrita nessa localidade. A proximidade da residência do animal com a mata favorece o contato com animais sinantrópicos, que podem atuar como elo de transmissão de Leishmania chagasi 1 .…”

“…Leishmaniasis is widespread in tropical and subtropical areas of Latin America, Europe, Africa and Asia and is increasingly becoming a major public health problem (WHO 1999). An increased prevalence of human and canine AVL has been reported in Brazil, not only in terms of the number of cases and but also in terms of the geographical dispersion of the disease (Feitosa et al 2000, Nunes et al 2001, Silva et al 2001, Cabrera et al 2003, França-Silva et al 2003. The disease is more prevalent among dogs than human beings and it has been shown that canine cases usually precede human cases.…”
