INTRODUCTION Acinetobacter baumannii has attained an alarming level of resistance to antibacterial drugs. Clinicians are now considering the use of older agents or unorthodox combinations of licensed drugs against multidrug-resistant strains to bridge the current treatment gap. We investigated the in vitro activities of combination treatments that included colistin with vancomycin, norvancomyci...

BACKGROUND In order to study the enzymatic carbapenem resistance mechanisms in Acinetobacter baumannii isolates from Argentina, we performed molecular characterization on 41 epidemiologically unrelated strains isolated from 1995 to 2006 with diminished susceptibilities to imipenem and meropenem. METHODOLOGY Acinetobacter baumannii isolates were identified with the ARDRA technique. The total g...

The drug resistance of microorganisms isolated from laboratory animals never treated with antibiotics is being reported consistently, while the number of laboratory animals used in medicine, pharmacy, veterinary medicine, agriculture, nutrition, and environmental and health science has increased rapidly in Korea. Therefore, this study examined the development of antimicrobial resistance in bact...

Acinetobacter baumannii is generally the most frequently isolated Acinetobacter species. Sequence analysis techniques allow reliable identification of Acinetobacter isolates at the species level. Forty-eight clinical isolates of Acinetobacter spp. were obtained from blood cultures at Tohoku University Hospital. These isolates were identified at the species level by partial sequencing of the RNA...

BACKGROUND/OBJECTIVE Several studies have described the epidemiological distribution of blaOXA-58-harboring Acinetobacter baumannii in China. However, there is limited data concerning the replicon types of blaOXA-58-carrying plasmids and the genetic context surrounding blaOXA-58 in Acinetobacter spp. in China. METHODOLOGY/PRINCIPAL FINDINGS Twelve non-duplicated blaOXA-58-harboring Acinetobac...

The aim of the present study is to investigate the types of healthcare-associated infections (HC-AIs) caused by Acinetobacter baumannii and the related antibiotic susceptibility patterns as well as the genotypic characteristics of the Acinetobacter baumannii isolates from our center. Sixty-nine Acinetobacter baumannii isolates originating from various samples collected from 69 pediatric patient...

Acinetobacter baumannii has emerged recently as a major cause of health care-associated infections due to the extent of its antimicrobial resistance and its propensity to cause large nosocomial outbreaks. Here we report the genome sequence of Acinetobacter baumannii TYTH-1 isolated in Taiwan during 2008.

Acinetobacter baumannii is a ubiquitous microrganism often able to colonize and survive in different environments. Currently it is one of the most common pathogens responsible for nosocomial infections, including outbreaks, especially in long-term care facilities. The aim of this study was to show the results of an environmental investigation and genotyping analysis of multidrug-resistant Acine...

Acinetobacter baumannii is among the most prevalent bacterial causes of combat-related infections on the battlefield. Antibiotic resistance and a poor understanding of the protective host immune responses make treatment difficult. Here, we report the genome sequences of four clinical Acinetobacter baumannii-A. calcoaceticus complex isolates exhibiting significant differences in virulence in a m...
