Primer aislamiento de Acanthamoeba spp. en agua de mar del sudeste bonaerense, Argentina
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.
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.
