The occurrence of American visceral leishmaniasis in the State of Espírito Santo, Brazil has always been associated with the presence of the Lutzomyia longipalpis vector. The geographic distribution of this vector in this state is related to the presence of specific geoclimatic characteristics, such as a dry climate, low elevations (< 450 m), steep slopes and rocky outcrops. The occurrence of human autochthonous cases of American visceral leishmaniasis in municipalities without these geoclimatic characteristics justifies the present study and our main goal was to test the association between the occurrence of American visceral leishmaniasis and the presence of the Lu. longipalpis. Sand flies were captured monthly from July 2006 to August 2007 using Shannon and CDC traps in two municipalities with records of autochthonous American visceral leishmaniasis and one with no record. We captured 13,112 sand flies, but no Lu. longipalpis was found. The absence of Lu. longipalpis and the possible role of another American visceral leishmaniasis vector in these localities were discussed.
巴西圣埃斯皮里图州的内脏利什曼病的发生一直与长刺舌蝇(Lutzomyia longipalpis)媒介的存在有关。该州这种媒介的地理分布与特定的地理气候特征有关,如干旱气候、低海拔(<450 米)、陡峭的山坡和岩石露头。在没有这些地理气候特征的城市中出现了人类内脏利什曼原虫病的本地病例,这证明了本研究的合理性,我们的主要目标是检验内脏利什曼原虫病的发生与长刺舌蝇的存在之间的关联。从 2006 年 7 月至 2007 年 8 月,我们使用 Shannon 和 CDC 陷阱,在两个有内脏利什曼原虫病本地病例记录的城市和一个没有记录的城市中,每月捕获沙蝇。我们共捕获了 13112 只沙蝇,但未发现长刺舌蝇。讨论了这些地方长刺舌蝇的缺失以及另一种内脏利什曼原虫病媒介可能发挥的作用。
