While typically saprophytic, these organisms are the only plant species known to have emerged as opportunistic pathogens for vertebrate animals including humans. The algae have been recognised as ubiquitous inhabitants of domestic and municipal sewage, considered as point sources of\n                    <jats:italic>Prototheca<\/jats:italic>\n                    contamination in natural aquatic systems. These observations, however, have been based on data from a very limited number of historical studies. The purpose of this work was to readdress the question of wastewater as a habitat for\n                    <jats:italic>Prototheca<\/jats:italic>\n                    , using a new and refined experimental methodology, and in light of the recently updated taxonomy and nomenclature of the\n                    <jats:italic>Prototheca<\/jats:italic>\n                    genus. Over a three\u2010month period, 96 samples were collected from three municipal wastewater treatment plants, at four different stages of the treatment process. The algae were recovered from 74 samples, which translates into an overall prevalence of 78.1%. The highest\n                    <jats:italic>Prototheca<\/jats:italic>\n                    population was found in raw sewage, and decreased progressively with each purification stage. The\n                    <jats:italic>Prototheca<\/jats:italic>\n                    cell count in the effluent was 100\u2010fold lower than in the untreated sewage, resulting in an algal removal efficiency of up to 99.9%. The occurrence of\n                    <jats:italic>Prototheca<\/jats:italic>\n                    in treated wastewater suggests that wastewater treatment plants may act as a pathway for the release of these algae into receiving natural environments. In both influent and effluent, species distribution was dominated by\n                    <jats:italic>Prototheca<\/jats:italic>\n                    species previously reported as pathogenic, with\n                    <jats:italic>P. wickerhamii<\/jats:italic>\n                    detected most frequently.
