This study assessed the in vitro antibacterial activity of combinations of amikacin and doxycycline or tigecycline against multidrug-resistant E. coli isolates. Twenty-four different pulsotypes, including 10 extended-spectrum β-lactamase (ESBL)-, 10 carbapenem-resistant, 2 New Delhi Metallo-beta-lactamase (NDM)- and 2 Klebsiella pneumoniae carbapenemase (KPC)-E. coli isolates were collected. Al...

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...

It has previously been shown that carbapenem-resistant Acinetobacter baumannii are frequently detected in Saudi Arabia. The present study aimed to identify the epidemiology and distribution of antibiotic resistance determinants in these bacteria. A total of 83 A. baumannii isolates were typed by pulsed-field gel electrophoresis (PFGE), and screened by PCR for carbapenemase genes and insertion s...

BACKGROUND Carbapenems are among the few useful antibiotics against multidrug resistant gram negative bacteria particularly those with extended spectrum beta lactamase. However resistance to carbapenems occurs and is mediated by mechanisms like loss of outer membrane proteins and production of beta lactamase that is capable of hydrolyzing carbapenems. An alert issued in the UK in 2009 warned of...

We investigated the basis of the carbapenem resistance of 17 multidrug-resistant Acinetobacter baumannii clinical isolates collected from 2004 to 2005 at the Saint George University Hospital in Beirut, Lebanon. A. baumannii isolates were clonally related and were susceptible to colistin and trimethoprim-sulfamethoxazole, susceptible or intermediate to ampicillin-sulbactam and meropenem, and res...

Antimicrobial resistance in bacteria is problematic in clinical settings and is a growing threat to public health. Multidrug-resistant and pandrug-resistant non-fermenters such as Acinetobacter spp. and Pseudomonas aeruginosa have recently emerged as a great concern worldwide. Particularly, the prevalence of carbapenem resistance in Acinetobacter spp. and P. aeruginosa is problematic, and emerg...

The genetic similarity of carbapenem-resistant Pseudomonas aeruginosa strains isolated in the Hospital Universitário São Francisco, Bragança Paulista, São Paulo, Brasil, was evaluated by pulsed field gel electrophoresis (PFGE). A unique clone was detected among 5 of 7 isolates, suggesting that cross-contamination might have played a role in the spread of carbapenem-resistant P. aeruginosa strai...

Background: Carbapenem-resistant Enterobacter (CRE) is an emerging threat spread rapidly around the world in past few years, posing substantial hazards to human health. Objective: The study was conducted evaluate prevalence of carbapenem resistance and detect carbapenemase producers phenotypically from patients a major tertiary care hospital, Bangladesh. Methods: Prospective cross-sectional Jul...

In recent years, different resistance genes have been found in Acinetobacter spp., especially in the species A. baumannii. We describe two isolates of carbapenem-resistant A. nosocomialis harboring ISAba1-blaOXA-23 and blaOXA-51 found in patients from the city of Porto Alegre, southern Brazil. To the best of the authors' knowledge, this is the first report of carbapenem-resistant A. nosocomiali...

Carbapenem-resistant Acinetobacter species are increasingly recognized as major nosocomial pathogens, especially in patients with critical illnesses or in intensive care. The ability of these organisms to accumulate diverse mechanisms of resistance limits the available therapeutic agents, makes the infection difficult to treat, and is associated with a greater risk of death. In this review, we ...
