The geographical distribution of carbapenemase-producing Enterobacteriaceae isolates per resistance mechanism, calculated as the number of confirmed isolates per 100,000 hospital admissions (a–c) based on Hospital Episode Statistics data for 2013–2014. Clear differences can be discerned between mechanisms, with high prevalence of KPC and high OXA-48-like prevalence in different parts of the North-West. d The geographical distribution of the majority carbapenemase (colours) reflects both single hospital outbreaks as well as multi-institutional outbreaks, such as in the Manchester and Lancashire referral regions
