    1. The M-MITT population was made up of patients who received at least one dose of study drug and had a baseline organism isolated.

    2. Tigecycline is considered a treatment option against these pathogens and one limitation of this study is the lack of data against such carbapenemase producing isolates. The high correlation between microbiological and clinical success rates for tigecycline coupled with the prolonged stability of pathogen susceptibility to tigecycline suggests that the current tigecycline breakpoints remain appropriate for microbiological and clinical use.
