Visceral leishmaniasis is a systemic infectious disease that can cause to a severe, potentially life-threatening chronic condition in humans. Risk factors for infection in urban areas have been associated with poor living conditions, the presence of sand fly vectors and infected pets. This study aimed to describe sand fly and canine infection in the neighborhoods of human visceral leishmaniasis occurrence in the city of Cuiabá, Mato Grosso State, central-western Brazil, reported between January 2005 and December 2006. A total of 1,909 sand flies were collected. They were predominantly males and the most frequent species were Lutzomyia cruzi (81.25%), Lutzomyia whitmani (13.88%) and Lutzomyia longipalpis (2.62%). The sand fly density was not significantly correlated with the variation of environmental factors. The prevalence of canine visceral leishmaniasis in the neighborhoods studied was 26.82% and it was found that areas with high density of vectors coincided with areas of high prevalence of dogs and those with the highest rates of human cases. The study of vectors and other potential hosts are essential for a good understanding of visceral leishmaniasis and the related public health concerns, aiming at the prevention and control of leishmaniasis in the city of Cuiabá, Mato Grosso State.
内脏利什曼病是一种全身性传染病，可导致人类患上严重的、可能危及生命的慢性病。城市地区的感染风险因素与生活条件差、白蛉传播媒介的存在以及受感染的宠物有关。本研究旨在描述2005年1月至2006年12月期间巴西中西部马托格罗索州库亚巴市人类内脏利什曼病发病社区的白蛉和犬类感染情况。共收集了1909只白蛉。它们主要为雄性，最常见的种类是克鲁兹卢蛉（81.25%）、惠特曼卢蛉（13.88%）和长须卢蛉（2.62%）。白蛉密度与环境因素的变化无显著相关性。在所研究的社区中，犬内脏利什曼病的患病率为26.82%，并且发现媒介高密度区域与犬类高患病率区域以及人类病例发生率最高的区域相吻合。对白蛉传播媒介和其他潜在宿主的研究对于充分了解内脏利什曼病及相关公共卫生问题至关重要，目的是在马托格罗索州库亚巴市预防和控制利什曼病。
