We first describe two novel variants of blaKPC, blaKPC-16 and blaKPC-17, which were identified in three Klebsiella pneumoniae isolates from a patient in Taiwan. KPC-16 and KPC-17 differed from KPC-2 by two (P202S and F207L) and a single (F207L) amino acid substitutions, respectively. All three isolates with identical pulsotype belonged to sequence type 11. The MICs of the three isolates for colistin and tigecycline were 0.5 μg/mL and 2 μg/mL, respectively. Moreover, an outbreak of at least 39 blaKPC-17-containing K.pneumoniae isolates is ongoing in southern Taiwan in 2014. Physicians should know that blaKPC-17-containing isolates can substantially threaten public health.
