Microarray analysis of global gene expression in mucoid Pseudomonas aeruginosa.
Pseudomonas aeruginosa is the dominant pathogen causing chronic respiratory infections in cystic fibrosis (CF). After an initial phase characterized by intermittent infections, a chronic colonization is established in CF upon the conversion of P. aeruginosa to the mucoid, exopolysaccharide alginate-overproducing phenotype. The emergence of mucoid P. aeruginosa in CF is associated with respirato...
متن کاملRegulated proteolysis controls mucoid conversion in Pseudomonas aeruginosa.
Overproduction of the exopolysaccharide alginate causes mucoid conversion in Pseudomonas aeruginosa and is a poor prognosticator in cystic fibrosis. The ECF sigma factor AlgU and its cognate anti-sigma factor MucA are two principal regulators of alginate production. Here, we report the identification of three positive regulators of alginate biosynthesis: PA4033 (designated mucE), PA3649 (design...
متن کاملGentamicin resistance in Pseudomonas aeruginosa: R-factor-mediated resistance.
By disk diffusion antimicrobial susceptibility testing, 11% of 313 consecutive strains of Pseudomonas aeruginosa, examined during July to October 1973, were resistant to gentamicin (minimal inhibitory concentration 12.5 to >100 mug/ml), and a further 31% were moderately resistant (6.25 to 12.5 mug/ml) to gentamicin at the University of Alberta Hospital in Edmonton, Canada. Of 45 gentamicin-resi...
متن کاملPrevalence and antimicrobial susceptibility of Pseudomonas aeruginosa mucoid and non-mucoid type.
Pseudomonas aeruginosa is a leading cause of nosocomial infections. One thousand two hundred and twenty strains of mucoid and non-mucoid types of P. aeruginosa isolated from different patients were examined at Siriraj Hospital from January 2001-October 2003. The prevalences of P. aeruginosa mucoid type and non-mucoid type were 3.6% and 96.4%, respectively. Susceptibility testing was performed b...
متن کاملPurification and Characterization of Alginate Lyase from Mucoid Pseudomonas aeruginosa Strain 214
Pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in compromised patients. The ability of Pseudomonas aeruginosa to produce chronic infection is based in part on its ability to biosynthesis of biofilm, and alginate is the major polysaccharide in the synthesized biofilm. So alginate degradation is very essential in the dispersion of Pseudomonas aeruginosa bi...
