Acinetobacter johnsonii rarely causes human infections. While most A. johnsonii isolates are susceptible to virtually all antibiotics, strains harboring a variety of β-lactamases have recently been described. An A. johnsonii Aj2199 clinical strain recovered from a hospital in Buenos Aires produces PER-2 and OXA-58. We decided to delve into its genome by obtaining the whole genome sequence of th...

The first step in the biofilm formation is the bacterial attachment to solid surfaces, which is dependent on the bacteria cell surface physico-chemical properties. The purpose of this work was to analyze the effect of pH on the physicochemical cell surface properties of Acinetobacter baumannii by two different methods. The cell surface properties were evaluated using the microbial adhesion to s...

Synergy between colistin and the signal peptidase inhibitor MD3 was tested against isogenic mutants and clinical pairs of Acinetobacter baumannii isolates. Checkerboard assays and growth curves showed synergy against both colistin-susceptible strains (fractional inhibitory concentration index [FICindex] = 0.13 to 0.24) and colistin-resistant strains with mutations in pmrB and phosphoethanolamin...

The genus Acinetobacter consists of 31 validly published species ubiquitously distributed in nature and primarily associated with nosocomial infection. We report the 3.4 Mb genome of Acinetobacter haemolyticus strain MTCC 9819(T). The genome has a G + C content of 40.0% and includes 3 rRNA genes (5S, 23S, 16S) and 65 aminoacyl-tRNA synthetase genes.

Clinical isolates of non-saccharolytic Acinetobacter species were observed to reduce nitrate.

Here, we report three genome sequences of bacteria isolated from murine proximal colonic tissue and identified as Acinetobacter parvus CM11, Acinetobacter radioresistens CM38, and Stenotrophomonas maltophilia BR12.

Nosocomial invasive infections due to Acinetobacter species are gradually increasing in the health care settings especially in intensive care units (ICUs).1 This retrospective study is designed to investigate risk factors associated with Acinetobacter bacteremia among children hospitalized in Dr. Behçet Uz Children’s Hospital, during 2005–2011. Nosocomial bacteremia was defined as isolation of ...

We evaluated three commercial colistin susceptibility testing methods using 213 bloodstream Acinetobacter isolates identified by gene sequencing. Compared to the agar dilution reference method, excellent categorical agreements (both 99.1%) were observed using Vitek 2 and Etest, compared to 87.3% (95.7% for Acinetobacter baumannii and 80.7% for non-baumannii Acinetobacter isolates) using MicroScan.

Introduction: The Gram-negative emerged an important nosocomial pathogen, especially in intensive care units. These bacteria are cause of health infections, specifically in intensive care units (ICUs). Recent reports present an increase in acinetobacters resistance to carbapenems. This study set out to determine the antibiotic resistance pattern and minimum inhibitory concentration (MIC) of car...

BACKGROUND Pan-resistant Acinetobacter infection has emerged as an important nosocomial pathogen in our inpatient neonates over the past few years. METHODOLOGY We performed a retrospective chart review during a five-year period (July 2003 - June 2008) of all neonates hospitalized in our neonatal intensive care unit (NICU) who developed Acinetobacter infection to identify mortality-associated ...
