“…The Monjolinho River belongs to a basin that covers São Carlos city and neighboring districts in the state of São Paulo, and it reaches a watershed dimension of 275 km 2 . The area belonging to São Carlos city is under intense anthropogenic activity and is highly impacted with domestic and industrial sewage, besides agricultural runoff [36,37]. Therefore, the present research examined five distinct sampling sites in which Naegleria spp.…”

The genus Naegleria, of free-living amoeba (FLA) group, has been investigated mainly due to its human health impact resulting in deadly infections and their worldwide distribution on freshwater systems. Naegleria fowleri, colloquially known as the “brain-eating amoeba”, is the most studied Naegleria species because it causes Primary Amoebic Meningoencephalitis (PAM) of high lethality. The assessment of FLA biodiversity is fundamental to evaluate the presence of pathogenic species and the possibility of human contamination. However, the knowledge of FLA distribution in Brazil is unknown, and to rectify this situation we present a research on identifying Naegleria spp. in the Monjolinho River, as a model study. The river is a public Brazilian freshwater source that crosses the city of São Carlos. Five distinct sampling sites were examined through limnological features, trophozoites culturing and PCR against internal transcribed spacers (ITS) regions and 5.8S rRNA sequence. The results identified N. philippinensis, N. canariensisi, N. australiensis, N.gruberi, N. dobsoni sequences, as well as a Vahlkampfia sequence. The methodology delineated here represents the first Brazilian Naegleria spp. study on a freshwater system. Our result stresses the urgency of a large scale evaluation of the presence of free-living amoebas in Brazil.

“…The information provided in both Figures 3.1 and 3.2 clarifies the diversity of samplingsites in regard to its location (rural, peri-urban and urban), vegetation structure, and human involvement with distinct habitats. The intense anthropogenic activity that comes from these urbanized regions exerts high impacts on the water system, mainly due to domestic and industrial sewage (257)(258). The results obtained from the lymnological evaluation of the five sampling sites reinforced the human impact in freshwater, according values displayed in Table3.1.…”
