The global prevalence of different genera of FLA in swimming pools and recreational waters (considering only studies that used molecular identification methods) is 10.01%, 15.38%, 16.40% and 16.06% forNaegleria spp., Acanthamoeba spp., Hartmanella spp. and Vermamoeba spp. respectively (Table 3). The results of Egger’s regression test, as well as the forest plot of the worldwide prevalence of each of these free-living amoeba genera in swimming pools and recreational waters can be seen in figures S1, S2, S3 and S4 of the supplementary material, respectively.
