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.

Acinetobacter spp. are common pathogenic bacteria. The genus includes 65 species, of which the calcoaceticus-Acinetobacter baumannii complex group has been identified as cause more than 80% hospital infections in immunocompromised patients. Existing phenotypic techniques not sufficient to accurately identify and distinguish clinically important 288 (60%, n = 480) ready-to-eat vegetable meat sam...

A small microcosm, based on optimized in vitro transformation conditions, was used to study the ecological factors affecting the transformation of Acinetobacter calcoaceticus BD413 in soil. The transforming DNA used was A. calcoaceticus homologous chromosomal DNA with an inserted gene cassette containing a kanamycin resistance gene, nptII. The effects of soil type (silt loam or loamy sand), bac...

A comparative study of the bacterial flora of the water of Chesapeake Bay and Tokyo Bay was undertaken to assess similarities and differences between the autochthonous flora of the two geographical sites and to test the hypothesis that, given similarities in environmental parameters, similar bacterial populations will be found, despite extreme geographic distance between locations. A total of 1...
