Objective. In this study, we show the Toxicological and phylogenetic characterization of a native Microcystis aeruginosa strain (named CAAT 2005-3)  isolated from a water body of Buenos Aires Province, Argentine.  Methods. A Microcistis aeruginosa strain was isolated from  the drainage canal of the sewage treatment in the town of Pila, Buenos Aires Province, Argentina and acclimated to laboratory conditions. The amplification of cpcBA-IGS  Phcocyanin (PC,  intergenic spacer and flanking regions) was carried out in order to build phylogenetic tree. An Exactive /Orbitrap mass spectrometer equipped with an electrospray ionization (ESI) source (Thermo Fisher Scientific, Bremen, Germany) were used for the LC/ESI-HRMS microcystins analysis.
