Activity of minocycline against Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae clinical isolates, with comparison to doxycycline and tigecycline

Diagn Microbiol Infect Dis. 2017 Aug;88(4):365-367. doi: 10.1016/j.diagmicrobio.2017.05.004. Epub 2017 May 11.

Abstract

We examined the in vitro activity of minocycline against 103 Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae isolates and found approximately half had susceptible (26%) or intermediate (26%) MICs. For a subset of 35 isolates, susceptibility was highest to tigecycline (71% FDA vs. 20% EUCAST) followed by minocycline (14%) and then doxycycline (6%).

Keywords: Extended-spectrum beta-lactamase; KPC; Multidrug resistance; Resistant; Tetracycline.
