We read with great interest C. S. Antonio et al.’s letter describing the high prevalence of Acinetobacter baumannii carrying blaOXA-143 in Brazilian hospitals (1). Recently, we carried out a similar study, and although the blaOXA-143 gene was identified, its frequency was lower than that reported by Antonio et al. (1). During 2008, a total of 803 Gram-negative bacillus isolates, 1 isolate per p...

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...

OBJECTIVE To detect genes encoding carbapenem resistance in Acinetobacter baumannii in an intensive care unit. METHODS A. baumannii isolates were recovered from various clinical specimens of hospitalized patients admitted to the Medical and Surgical intensive care units of a tertiary care centre in Pune. Bacterial identification was performed by routine conventional microbial culture and bioc...

In this study, we present the complete genome sequence of a blaOXA-58-producing Acinetobacter baumannii strain, sampled from a Mexican hospital and not related to the international clones.

Acinetobacter baumannii causes life-threatening infections in critically ill patients, with subsequent treatments mostly based on carbapenems. Unfortunately, oxacillinases (OXAs) that hydrolyze carbapenems, especially OXA-23, have dramatically spread in humans and even started to be reported in animals (1–4). As OXA-producing isolates are still rare in nonhuman sources, a comprehensive picture ...

The aim of the study was to investigate the resistant mechanisms and homology of imipenem-resistant Acinetobacter baumannii (A. baumannii). A total of 46 non-duplicate imipenem‑resistant A. baumannii clinical isolates were collected from three tertiary hospitals between July, 2011 and June, 2012. The minimal inhibitory concentrations (MICs) of antimicrobial agents were determined using the agar...

Salmonella Isangi is an infrequent serovar that has recently been reported in several countries due to nosocomial infections. A considerable number of reports indicate multidrug resistance, especially cephalosporins, which could potentially pose a risk public health worldwide. Genomic analysis excellent tool for monitoring the emergence microorganisms and related factors. In this context, aim s...
