Molecular epidemiology of OXA-1054, a novel carbapenem-hydrolysing Class D β-lactamase, in Enterobacteriaceae isolated from wastewaters

Key Points

• This research aims to investigate the molecular epidemiology of OXA-1054 in specific bacterial groups isolated from wastewater.
• Analysis of Enterobacteriaceae isolates from wastewaters
• Examination of the genetic structure related to OXA-1054
• Assessment of the potential for horizontal gene transfer
• Identified OXA-1054 as part of a mobile genetic module that enhances transfer between bacteria.
• Highlighted the significance of monitoring OXA variants across clinical and environmental contexts.
