BACKGROUND NXL104 potentiates ceftazidime and ceftaroline against Enterobacteriaceae with extended-spectrum, AmpC, KPC and OXA β-lactamases. We examined whether similar potentiation was obtained against non-fermenters, which are less permeable than Enterobacteriaceae and have more potent efflux. METHODS MICs of ceftazidime+NXL104 (with NXL104 at 4 mg/L) and comparators were determined by CLSI...

Objective(s):Antibiotic resistance in Acinetobacter baumannii and outbreaks caused by this organism have been reported from several areas of the world. The present study aimed at determining the antibiotic susceptibility profiles and the distribution of OXA-type beta-lactamases among Iranian Acinetobacter baumannii isolates from Qom of Iran. Materials and Methods: For this study, 108 non-duplic...

OBJECTIVES The aim of this study was to evaluate the occurrence and dissemination of acquired carbapenem-hydrolysing class D beta-lactamase (class D carbapenemase)- and metallo-beta-lactamase (MBL)-encoding genes among Acinetobacter spp. isolates recovered from medical centres in the Asia-Pacific (APAC) region. METHODS During 2006-07, 41 medical centres located in 10 countries in the APAC reg...

The molecular epidemiology of multidrug-resistant Acinetobacter baumannii was investigated in two intensive care units of the V. Monaldi university hospital in Naples, Italy, from May 2006 to December 2007. Genotype analysis by pulsed-field gel electrophoresis (PFGE), trilocus sequence-based typing (3LST), and multilocus sequence typing (MLST) of A. baumannii isolates from 71 patients identifie...

Acinetobacter baumannii is an important nosocomial pathogen, commonly causing infections in immunocompromised patients. It is increasingly reported as a multidrug-resistant organism, which is alarming because of its capability to resist all available classes of antibiotics including carbapenems. The aim of this study was to examine the genetic and epidemiological diversity of A. baumannii isola...
