Visualisation of carbapenemase-producing Enterobacterales (CPE) per species over time in patient and environmental samples

OXA-48 (blue), VIM (orange) and NDM-1 (yellow) producing bacterial isolates from patients (upper panel) and from environmental samples (lower panel) detected at the geriatric department over a 10-year timespan (2012–2021). Wastewater pipe isolates (2022) are not included in the lower panel. Beside standard cleaning protocols (grey), bleach was used daily in toilets (green) from December 2019 until January 2021. On the right side the flow charts show the number of selected isolates for whole genome sequencing (WGS)
