Twenty-seven colistin-resistant, carbapenemase-producingKlebsiella pneumoniae isolates were identified from hospitals in Serbia. All isolates werebla CTX-M-15 positive; ST101, ST888, ST437, ST336, and ST307 werebla OXA-48 positive; and ST340 wasbla NDM-1 positive. ST307 had an insertion, and ST336 had a premature stop codon in themgrB gene. Amino acid substitutions were detected in PmrAB of isolates ST101, ST888, ST336, and ST307. Themcr-1 andmcr-2 were not detected. An increase inphoP ,phoQ , andpmrK gene transcription was detected for all sequence types.
