A 65 year old man was admitted with segmental consolidation of the left upper lobe after having stayed in a hotel for 2 days. He deteriorated rapidly on conventional antibiotic therapy and required ventilatory support. Acinetobacter calcoaceticus var. anitratus was grown from the sputum and blood cultures, which was treated with a combination of anti-pseudomonal agent, aminoglycoside and cotrim...

80 Acinetobacter strains were studied. Their differentiation according to the specific belonging showed that 55 belonged A. calcoaceticus var. anitratum species and 25 lwoffi. It was established are multi dry resistant. In particular they 100% resistance ampicillin, carbenicillin, erythromycin, methicillin, oxacillin, tetracycline, oleandomycin, streptomycin, rondomycin, linkomycin. According o...

Acinetobacter baumannii is an emerging nosocomial pathogen, and therefore high-quality genome assemblies for this organism are needed to aid in detection, diagnostic, and treatment technologies. Here we present the improved draft assembly of A. baumannii ATCC 19606 in two scaffolds. This 3,953,621-bp genome contains 3,750 coding regions and has a 39.1% G+C content.

This study was conducted to compare the prevalences of antimicrobial resistance profiles of clinical isolates in the Acinetobacter calcoaceticus-Acinetobacter baumannii complex from sterile and nonsterile sites and to further study the relationship of antimicrobial resistance profiles and genospecies by amplified rRNA gene restriction analysis (ARDRA). A total of 1,381 isolates were tested with...

A total of 2582 non-duplicate clinical Acinetobacter spp. isolates were collected to evaluate the performance of four identification methods because it is important to identify Acinetobacter spp. accurately and survey the species distribution to determine the appropriate antimicrobial treatment. Phenotyping (VITEK 2 and VITEK MS) and genotyping (16S rRNA and rpoB gene sequencing) methods were a...

24 www.jkscience.org Vol. 11 No. 1, January-March 2009 Acinetobacter are opportunistic pathogens that readily colonize patients with compromised host defences. Acinetobacter calcoaceticus, the species usually involved in human infection, causes disease chiefly in a hospital setting usually associated with respiratory therapy equipment and indwelling catheters. Sepsis, pneumonia and urinary trac...

The carbapenem-hydrolyzing class D β-lactamase OXA-253 was identified in an Acinetobacter baumannii clinical isolate belonging to sequence type 113 (ST113) in Brazil. OXA-253 shares 93.8% amino acid identity with OXA-143. The blaOXA-253 gene is located on a ca. 20-kb plasmid. The genetic environment of the blaOXA-253 gene shares the highest identity with ubiquitous GR2 group plasmids usually ca...

The role of Acinetobacter nosocomialis and Acinetobacter pittii, which belong to the A. calcoaceticus-A. baumannii complex, in hospital-acquired infections is increasingly recognized. Here we describe a retrospective cohort study of hospital-acquired A. calcoaceticus-A. baumannii complex infections at a university hospital in Thailand. A total of 222 unique cases were identified between January...
