Colistin-resistant Acinetobacter baumannii: beyond carbapenem resistance.
BACKGROUND With an increase in the use of colistin methansulfonate (CMS) to treat carbapenem-resistant Acinetobacter baumannii infections, colistin resistance is emerging. METHODS Patients with infection or colonization due to colistin-resistant A. baumannii were identified at a hospital system in Pennsylvania. Clinical data were collected from electronic medical records. Susceptibility testi...
متن کاملHeteroresistance to colistin in multidrug-resistant Acinetobacter baumannii.
Multidrug-resistant Acinetobacter baumannii has emerged as a significant clinical problem worldwide and colistin is being used increasingly as "salvage" therapy. MICs of colistin against A. baumannii indicate its significant activity. However, resistance to colistin in A. baumannii has been reported recently. Clonotypes of 16 clinical A. baumannii isolates and ATCC 19606 were determined by puls...
متن کاملCarbapenem-resistant Acinetobacter baumannii outbreak at university hospital
Nineteen clonally related imipenem-resistant Acinetobacter baumannii isolates were recovered from eight intensive care unit patients. All isolates harboured bla OXA-51-like β-lactamase genes and showed the absence of 22 kDa fraction in outer membrane porin profile analysis. It suggests a combination of two mechanisms as responsible for carbapenem-resistant phenotypes.
متن کاملCharacterization of carbapenem-resistant Acinetobacter baumannii clinical isolates in a tertiary care hospital in Saudi Arabia.
This study characterized the occurrence of carbapenem resistance of Acinetobacter baumannii isolates in a tertiary care hospital in Saudi Arabia. From January 2010 until February 2012, Acinetobacter spp. isolates were collected from different wards and were identified using Vitek 2 system and 16S rRNA gene sequencing. Vitek 2 system and Etest were used for susceptibility testing. PCR and Pulse ...
متن کاملCarbapenem-resistant Acinetobacter baumannii
To the editor: We read with interest the paper of Hrabák et al. [1] on the isolation of a blaNDM-1-carrying Acinetobacter baumannii strain. However, although the authors believed to be the first in the Czech Republic to report on a New Delhi metallo-beta-lactamase-1 (NDM-1)-producing bacterium, there have been other reports on the same A. baumannii strain in the country [2,3]. Here, we would li...
