Pseudomonas aeruginosa, an opportunistic human pathogen and ubiquitous environmental bacterium, is capable of forming specialized bacterial communities, referred to as biofilm. The results of this study demonstrate that the unique environment of the cystic fibrosis (CF) lung seems to select for a subgroup of autoaggregative and hyperpiliated P. aeruginosa(More)
Pathogenesis of Pseudomonas aeruginosa is controlled to a major extent by the two quorum-sensing systems las and rhl. The previously uncharacterized gene PA2591 was identified as a major virulence regulator, vqsR, in the quorum-sensing hierarchy. vqsR is a member of the LuxR family and possesses a las box in its upstream region. Transposon inactivation of(More)
Enterohepatic Helicobacter species infect the intestinal tracts and biliary trees of various mammals, including mice and humans, and are associated with chronic inflammatory diseases of the intestine, gallstone formation, and malignant transformation. The recent analysis of the whole genome sequence of the mouse enterohepatic species Helicobacter hepaticus(More)
In this paper, we report the synthesis of Pseudomonas aeruginosa cDNA in the presence of oligo(dT) primers. Hybridization of oligonucleotide DNA microarrays indicates that under the experimental conditions used, at least 43.7% of the expressed genes from P. aeruginosa PAO1, representing many different functional classes, can be detected by using(More)
The heterogeneous environment of the lung of the cystic fibrosis (CF) patient gives rise to Pseudomonas aeruginosa small colony variants (SCVs) with increased antibiotic resistance, autoaggregative growth behavior, and an enhanced ability to form biofilms. In this study, oligonucleotide DNA microarrays were used to perform a genome-wide expression study of(More)
