  1. aDrug susceptibility to tigecycline was not tested on all isolates. Overall the results were only available on 460 isolates, among which 372 isolates are susceptible to 3GC. In urosepsis group, the results of drug susceptibility to tigecycline were only available on 209 isolates, among which 179 isolates are susceptible to 3GC. In community-acquired bacteremia group, the results of drug susceptibility to tigecycline were only available on 209 isolates, among which 187 isolates are susceptible to 3GC
