Article Title: In vitro activity of ceftazidime-avibactam against carbapenem-resistant and hypervirulent Klebsiella pneumoniae isolates
Abstract: Carbapenem-resistant and hypervirulent Klebsiella pneumoniae (CR-hvKp) strains have emerged while antimicrobial treatment options remain limited. Herein, we tested the in vitro activity of ceftazidime-avibactam and other comparator antibiotics against 65 CR-hvKp isolates. Ceftazidime-avibactam, colistin, and tigecycline are highly active in vitro against CR-hvKp isolates (MIC90, 1 g/ml), including K. pneumoniae carbapenemase 2 (KPC-2)-producing ST11 CR-hvKp. On the basis of previous clinical experience and the in vitro data presented herein, we posit that ceftazidime-avibactam is a therapeutic option against CR-hvKp infections.
