Analysis of clinical isolates of the family Enterobacteriaceae revealed a very high degree of diversity in β-lactam resistance levels and patterns, which was attributed to several factors, such as the production of other β- lactamases including additional ESBLs, possible quantitative variations in CTX-M-3 expression, segregation of AmpC derepressed mutants, and permeability alterations.

The results suggest that, like Escherichia coli and Klebsiella pneumoniae, E. cloacae harbours clonal lineages of increased epidemic potential that may be associated with resistance spread.
Ceftazidime-hydrolysing CTX-M-15 extended-spectrum beta-lactamase (ESBL) in Poland.

- Biology, MedicineJournal of Antimicrobial Chemotherapy
- 2002
Three cefotaxime- and ceftazidime-resistant Enterobacteriaceae isolates recovered during 1998-2000 in two Polish hospitals were found to produce CTX-M-15, which indicated the independent selection of the ESBL gene in the two countries.

- 5 May 2008
The survey documented both specific and more global characteristics of the epidemiology of the β-lactamase-mediated resistance in enterobacteria from Polish hospitals and demonstrated that the ESBL frequency has reached an alarming level.

Strains with KPCs spread rapidly and cause outbreaks; in hospitals on the east coast of the United States and in Israel, they have already become endemic and are likely to become endemic.

The aim of this study was to characterize the clonal structure, extended-spectrum β-lactamases (ESBLs), and acquired AmpC-like cephalosporinases in the Escherichia coli populations collected.
Molecular Characteristics of KPC-Producing Enterobacteriaceae at the Early Stage of Their Dissemination in Poland, 2008–2009

The striking diversity of KPC producers at the early stage of dissemination could result from several introductions of these bacteria into the country, their multidirectional evolution during clonal spread, and transfer of the plasmids.
