Antimicrobial Susceptibility among Pathogens Collected from Hospitalized Patients in the United States and In Vitro Activity of Tigecycline, a New Glycylcycline Antimicrobial

Abstract

The activities of tigecycline and comparators against isolates collected from 76 U.S. centers between January 2004 and September 2005 were assessed. Tigecycline MIC(90)s were < or =2 microg/ml for Klebsiella pneumoniae, Klebsiella oxytoca, Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae, Serratia marcescens, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, and Streptococcus agalactiae.
