In vitro activity of tigecycline and comparators on Acinetobacter spp. isolates collected from patients with bacteremia and MIC change during the Tigecycline Evaluation and Surveillance Trial, 2004 to 2008.

Abstract

The Tigecycline Evaluation and Surveillance Trial is a global surveillance study established in 2004 to monitor the activity of tigecycline, a new glycylcycline, and several comparators against an array of important Gram-positive and Gram-negative pathogens. In this study, we examined 1591 isolates of Acinetobacter from blood samples collected from 352 centers globally between 2004 and 2008. Tigecycline showed an MIC(90) (1 microg/mL) globally, with a maximum regional value of 4 microg/mL (Middle East) reported. Antimicrobial susceptibility was notably higher among nonintensive care unit (non-ICU) isolates than isolates collected from ICUs. Carbapenem-resistant Acinetobacter were more prevalent in the Middle East, Latin America, and Asia/Pacific rim than in Europe or North America. Tigecycline creep was noted between 2004 and 2007, corresponding closely to changes in MIC(90).
