Abstract

Free-living amoebae (FLA) of the genus Acanthamoeba are ubiquitous and amphizoic protozoa that colonize aquatic and terrestrial habitats and can serve as reservoirs for other microorganisms. They are considered econoses that can cause severe and rare pathologies. Due to limited epidemiological data available, the objective of this study was to investigate the presence of Acanthamoeba in coastal wetlands of the southeast of Buenos Aires province and evaluate their association with bacteriological and environmental variables. From February 2021 to July 2022, 22 seawater samples were collected at different points along the coast of the city of Mar del Plata (Buenos Aires, Argentina). Environmental parameters were determined and physicochemical and bacteriological studies, morphological identification, cultures and molecular typification were conducted. Regardless of the environmental and bacteriological variables, the presence of Acanthamoeba spp. was molecularly confirmed in 54.54% of the samples, being the first report of these protozoa in seawater in Argentina.

[首次在布宜诺斯艾利斯东南部（阿根廷东南部）的海水中分离到棘阿米巴原虫]。

棘阿米巴属（Acanthamoeba）的自由生活阿米巴虫（FLA）是一种无处不在的两栖原生动物，它们在水生和陆生生境中定居，并可成为其他微生物的贮藏库。它们被认为是可导致严重和罕见病症的经济动物。由于现有的流行病学数据有限，本研究旨在调查布宜诺斯艾利斯省东南部沿海湿地中是否存在棘阿米巴虫，并评估其与细菌学和环境变量的关联。从 2021 年 2 月到 2022 年 7 月，在马德普拉塔市（阿根廷布宜诺斯艾利斯）沿岸的不同地点收集了 22 份海水样本。确定了环境参数，并进行了物理化学和细菌学研究、形态鉴定、培养和分子分型。无论环境和细菌学变量如何，54.54%的样本经分子鉴定确认存在棘阿米巴属，这是阿根廷首次报告海水中存在这些原生动物。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
