A 2-month survey of extended-spectrum β-lactamase (ESBL) producers was performed in a Czech hospital. Klebsiella pneumoniae produced SHV-2, -5, or -12, Escherichia coli produced CTX-M-9 or -15, and other species produced TEM-92 or -132. All K. pneumoniae and E. coli isolates belonged to sequence types (STs) or clonal complexes (CCs) spread across the world (K. pneumoniae clonal complex 11 [CC11], CC14, and sequence type 101 [ST101] and E. coli CC31, CC73, CC131, and CC405) and carried various plasmids (mainly with A/C- and FII-type replicons).
