In the last few years, phenotypically carbapenem resistant Acinetobacter strains have been identified throughout the world, including in many of the hospitals and intensive care units (ICUs) of Australia. Genotyping of Australian ICU outbreak-associated isolates by pulsed-field gel electrophoresis of whole genomic DNA indicated that different strains were cocirculating within one hospital. The ...

ABSTRACT       Background and Objective: Extended-spectrum beta-lactamases (ESBL) are widely produced by Escherichia coli strains. The aim of this study was to determine frequency of blaOXA-1 and blaSHV genes in E.coli strains isolated from patients hospitalized in city of Rasht, Iran.        Methods: In this cross-sectional study, ...

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...

Objective(s): Acinetobacter pittii has become an emerging opportunistic noscomial pathogen worldwide with multi-drug resistance. In the present study, an A. pittii strain was isolated from bronchoalveolar lavage fluid sample harboring both OXA-58 and NDM-1carbapenemase producing genes. The mechanisms of carbapenem resistance of the A. pittii strain was investigated.Materials and Methods: Carbap...

This study identified, using PCR blaoxA,,23 encoding carbapenamase OXA-23 in 42 carbapenem-resistant Acinetobacter baumannii (CRAB) clinical iso- lates and blaOXA-40-like encoding carbapenamase OXA-40-like in one isolate (the first such Thai sample) obtained from patients admitted to Hua Hin Hospital, Thailand during November 2011-September 2012. Using repetitive extragenic palindromic PCR, the...

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 ...

Background Antimicrobial resistance is an important factor threatening human health. It is widely accepted that antibiotic resistant bacteria such as Escherichia coli (E. coli) released from humans and animals into the water sources, can introduce their resistance genes into the natural bacterial community. Objective The aim of this study was to investigate the prevalence of blaTEM, blaCTX, b...
