Objectives Colistin resistance rates are rising globally among multidrug-resistant Gram-
negative bacilli, including Acinetobacter baumannii (A. baumannii). A new type of resistance …

Acinetobacter baumannii is an opportunistic pathogen that poses an increasing threat in the
health-care community. Colistin is one of the promising options for treatment of multidrug …

Colistin is one of the last remaining active antibiotics against multidrug resistant Gram-
negative bacteria. However, several recent studies reported colistin-resistant (ColR) …

Colistin is one of the most effective alternatives for treating Acinetobacter baumannii
infections. The aim of this study was to determine colistin resistance and heteroresistance …

Background Colistin-resistant/carbapenem-resistant Acinetobacter baumannii is a
significant challenge for antibiotic treatment and infection control policies. Since 2012, in …

Background and Aim: Colistin is increasingly being used as a “last-line” therapy to treat
infections caused by multidrug-resistant (MDR) Acinetobacter baumannii isolates, when …

Background: Colistin is one of the few remaining options for carbapenem-resistant
Acinetobacter baumannii (A. baumannii); however, emergence of resistance from …

Aim: The aim of this study was to investigate the prevalence and the mechanisms of
carbapenem and colistin resistance in Acinetobacter baumannii clinical isolates in an …

Purpose Colistin is a drug of last resort for treating multidrug-resistant Acinetobacter
baumannii infections. Unfortunately, colistin-resistant A. baumannii (CoR-AB) has been …

In this study, antimicrobial resistance patterns, carbapenemase production, carbapenem-
hydrolysing class D OXA-type β-lactamase (CHDL)-encoding genes and ISAba insertion …
