Ascogregarina infections from South America were recently documented in Brazil and Argentina. The aim of this study was to report our recent findings on the prevalence and seasonality of Ascogregarina culicis in Aedes aegypti adults from temperate Argentina. Between December 2003 and May 2005, 391 females of Ae. aegypti were captured in two areas of Greater Buenos Aires. Overall prevalence of A. culicis was 21.2% (83/391), and a significant difference was observed between both areas (28.4% vs. 8%). Infected Ae. aegypti were found from November to May, with highest values in March (24-37%). Parasite prevalence and host abundance showed similar seasonal patterns. Our observations suggest a widespread infestation of A. culicis among Ae. aegypti populations from temperate Argentina.
最近在巴西和阿根廷记录到了来自南美洲的库蠓艾氏孢子虫感染情况。本研究的目的是报告我们最近关于温带阿根廷地区埃及伊蚊成虫中库蠓艾氏孢子虫的流行率和季节性的研究结果。在2003年12月至2005年5月期间，在大布宜诺斯艾利斯的两个地区捕获了391只埃及伊蚊雌蚊。库蠓艾氏孢子虫的总体流行率为21.2%（83/391），两个地区之间观察到显著差异（28.4%对8%）。受感染的埃及伊蚊在11月至5月间被发现，3月份的感染率最高（24% - 37%）。寄生虫流行率和宿主丰度呈现出相似的季节性模式。我们的观察结果表明，库蠓艾氏孢子虫在温带阿根廷的埃及伊蚊种群中广泛存在。
