Fructooligosacharides Reduce Pseudomonas aeruginosa PAO1 Pathogenicity through Distinct Mechanisms
Pseudomonas aeruginosa is ubiquitously present in the environment and acts as an opportunistic pathogen on humans, animals and plants. We report here the effects of the prebiotic polysaccharide inulin and its hydrolysed form FOS on this bacterium. FOS was found to inhibit bacterial growth of strain PAO1, while inulin did not affect growth rate or yield in a significant manner. Inulin stimulated...
متن کاملPseudomonas aeruginosa PAO1
Growth and conversion to the mucoid phenotype by nonmucoid Pseudomonas aeruginosa PAO1 was studied in a chemostat system under conditions designed to reflect those likely to be present during chronic infection in the lung in cystic fibrosis patients. Mucoid variants were consistently isolated during continuous culture in the presence of 0.3 M NaCl or 5 or 10% glycerol. Mucoid subpopulations wer...
متن کاملAutoinducer-2 Facilitates Pseudomonas aeruginosa PAO1 Pathogenicity in Vitro and in Vivo
Bacterial communication systems, such as quorum sensing (QS), have provided new insights of alternative approaches in antimicrobial treatment. We recently reported that one QS signal, named as autoinducer-2 (AI-2), can affect the behaviors of Pseudomonas aeruginosa PAO1 in a dose-dependent manner. In this study, we aimed to investigate the effects of AI-2 on P. aeruginosa PAO1 biofilm formation...
متن کاملDetection of Neuraminidase Activity in Pseudomonas aeruginosa PAO1
Objective(s) Some properties of neuraminidase produced by Pseudomonas aeruginosa PAO1 growth in a defined medium (BHI) were examined and evaluated for its features. Materials and Methods The obtained supernatant enzyme of P. aeruginosa PAO1 cultures was used in a sensitive fluorometric assay by using 2'-(4-methylumbelliferyl) a-D-N acetylneuraminic acid as substrate. As hydrolyzing MUN with ...
