Taxonomic profile of (A) carbapenem-resistant and (B) blaKPC-or-NDM-positive isolates recovered from sewage and water samples. A Carbapenem-resistant isolates recovered from downstream water and sewage samples form a more diverse set of strains in comparison with the isolates from upstream water samples. Enterobacteria, especially the Klebsiella-Enterobacter group, are overrepresented among carbapenem-resistant isolates recovered from sewage and downstream samples. In contrast, carbapenem-resistant isolates from upstream water samples are mostly represented by intrinsically resistant, saprophyte species. B Strains harboring blaKPC or blaNDM genes (blaKPC-or-NDM) were not recovered from upstream water samples. Klebsiella-Enterobacter group predominates among blaKPC-or-NDM strains recovered from downstream water and sewage samples and is followed by blaKPC-or-NDMAeromonas strains
