Description
Summary:The aim was to review the methodologies used in the concentration of intestinal parasites in different water samples in Latin America. The period of the review was between September and November 2022. Of the total number of articles (N = 87), the search engine with the most articles matching the specified keywords was Google Scholar (56.3% = 49 articles), and Brazil was the country that published the most articles (28.7%). Most of the studies were conducted for surface waters (75.9%) and used methodologies with physical separation without subsequent parasitological concentration (76.9%). However, the ultrafiltration method (UFM) with subsequent parasitological concentration recovered a greater number and type of parasite species. The descriptive study of the review shows that the procedure of using UFM with a parasitological method of flotation and sedimentation would allow an efficient concentration of the parasite species present in the water sample.
