GERTISER, María Laura et al. Acanthamoeba spp. in indoor swimming pools in Bahía Blanca city, Buenos Aires province, Argentina. Acta bioquím. clín. latinoam. [online]. 2010, vol.44, n.4, pp.697-703. ISSN 0325-2957.

Acanthamoeba spp. has been isolated from many habitats, including swimming pools. Investigations on its distribution are relevant because many of its species cause human diseases. The aim of the present work was to investigate, isolate and characterize protozoan of the genus Acanthamoeba from indoor swimming pools in Bahía Blanca, Argentina, in the four seasons, during the 2007-2008 period. Seven pools were studied and samples were collected from the bottom, surface and wall by scraping them. Besides, samples for bacteriological analysis were taken from each pool. The samples were analyzed by direct observation and by culturing on non nutritive agar at 37 °C and at 42 °C. The generic identification was performed according to the morphologic characteristics of cysts and trofozoites, while the amoebo-flagellate transformation test was carried out to identify Naegleria. Free-living amoebas were isolated from five of the seven swimming pools examinated, in at least one season. Naegleria genus was not found as the amoebo-flagellate transformation tests were negative in all samples. All the isolations corresponded to the genus Acanthamoeba belonging to Pussard & Pons morphological Groups II and III. Although elimination of Acanthamoeba from the water is difficult because it is a ubiquitous protozoan. which is highly resistant to the commonly used disinfectants, a thorough cleaning of the pools to minimize the risks of infection is recommended.
