Sequencing of the most prevalent carbapenem-resistant sequence types (STs) isolated from hospital wastewater. Clonal dissemination of carbapenem-resistant bacteria

In this study the most frequent carbapenem-resistant strains (ST 147 Klebsiella pneumoniae and ST 823 and ST 235 Pseudomonas aeruginosa) isolated mainly from hospital wastewater in the HyReKA project were sequenced. Core genome MLST was used to demonstrate the presence of these clones from the patients rooms, in the wastewater and in some cases even in in the effluent of the wastewater treatment plant.
