The main objective of this work was to carry out a systematic analysis through the literature on the main microorganisms found in impacted aquatic environments and to relate the data with the risks to public health. This review was planned, conducted and reported following the PRISMA protocol, which was used the PECO strategy. There performed searches for studies using the electronic databases PubMed, Medline and LILACS in September 2021, using the controlled search strategy: “Bacteria” and “Ecosystem” and “Environment” and “Aquatic” and “Impacted. The studies that met the eligibility criteria were considered eligible, with the participation of two independent reviewers. There found 1058 studies, of which were chosen only 31 to compose the results of this systematic review. Because of the results, there observed that the predominant bacterial genera in freshwater are: Pseudomonas, Aeromonas, and Escherichia, with the Asian continent presenting more varieties of bacterial species detected. These microorganisms are responsible for causing diseases that can lead to death, which shows the importance of constantly monitoring these ecosystems.展开更多
