The prevalence of the currently known Acinetobacter species and related trends of antimicrobial resistance in a Dutch university hospital were studied. Between 1999 and 2006, Acinetobacter isolates from clinical samples were collected prospectively. Isolates were analyzed by amplified fragment length polymorphism fingerprinting. For species identification, a profile similarity cutoff level of 5...

OBJECTIVES New antibacterial agents are required for the treatment of infections caused by multidrug-resistant (MDR) Acinetobacter spp. Whether tigecycline constitutes an effective treatment option or not, is not well established. We sought to evaluate the available evidence regarding the microbiological activity and clinical effectiveness of tigecycline for MDR (including the subset of carbape...

OBJECTIVES The study investigated the species distribution, antibiotic susceptibility patterns and genotypic resistance characteristics of 113 consecutive blood culture isolates of Acinetobacter species collected between 2005 and 2007 throughout Norway. METHODS Species identification was performed by partial rpoB sequence analysis, and verified by 16S rDNA and recA sequence analyses. Suscepti...

The genus Acinetobacter encompasses multiple nosocomial opportunistic pathogens that are of increasing worldwide relevance because of their ability to survive exposure to various antimicrobial and sterilization agents. Among these, Acinetobacter baumannii, Acinetobacter nosocomialis, and Acinetobacter pittii are the most frequently isolated in hospitals around the world. Despite the growing inc...

Thirty-one strains of Acinetobacter species, including type strains of the 18 genomic species and 13 clinical isolates, were compared by amplified ribosomal DNA restriction analysis (ARDRA), random amplified polymorphic DNA analysis (RAPD), and amplified fragment length polymorphism (AFLP) fingerprinting. ARDRA, performed with five different enzymes, showed low discriminatory power for differen...

Acinetobacter spp. are responsible for an increasing number of opportunistic, nosocomial infections. They have been isolated from diverse inanimate objects in the hospital environment and are resistant to most of the commonly used antibiotics. Existing media for the isolation of Acinetobacter spp. are either nonselective, allowing the growth of unwanted bacteria, or too inhibitory, inhibiting t...

OBJECTIVES Bacteria of the genus Acinetobacter are increasingly being isolated in hospitals and are recognized as emerging nosocomial pathogens. Species identification is difficult and there is a need for simple molecular methods to differentiate between the species. Naturally occurring oxacillinase genes (blaOXA) have been identified in several Acinetobacter species and their detection by PCR ...

The hygiene hypothesis states that the tremendous increase in atopic diseases correlates significantly with less contact to microbes in childhood. Here, we report the draft genome sequence of Acinetobacter lwoffii F78, a rural cowshed isolate with strong allergy-protective properties that contains an 8,579-bp plasmid.

An outbreak of hospital-acquired Acinetobacter baumannii infections, caused by a bla(OXA-23)-positive carbapenem-resistant strain belonging to international clone II/ST2, was detected in Latvia. The strain was partially equipped with the armA gene and the intI1-aacA4-catB8-aadA1-qacEΔ1 class 1 integron. In addition, the strain carried AbaR25, a novel AbaR4-like resistance island of ~46,500 bp c...
