Abstract:
Pseudomonas aeruginosa is a facultative pathogen that can cause, inter alia, acute or chronic pneumonia in predisposed individuals. The gram-negative bacterium displays considerable genomic and phenotypic diversity that is also shaped by small molecule secondary metabolites. The discrimination of virulence phenotypes is highly relevant to the diagnosis and prognosis of P. aeruginosa infections. In order to discover small molecule metabolites that distinguish different virulence phenotypes of P. aeruginosa, 35 clinical strains were cultivated under standard conditions, characterized in terms of

Abstract:
Pseudomonas aeruginosa contributes to frequent, persistent, and, often, polymicrobial respiratory tract infections for individuals with cystic fibrosis (CF). Chronic CF infections lead to bronchiectasis and a shortened lifespan. P. aeruginosa expresses numerous adhesins, including lectins known to bind the epithelial cell and mucin glycoconjugates. Blocking carbohydrate-mediated host–pathogen and intra-biofilm interactions critical to the initiation and perpetuation of colonization offer promise as anti-infective treatment strategies. To inform anti-adhesion therapies, we profiled the monosacc

Pseudomonas aeruginosa is one of the most commonly isolated species among non-fermenting Gram-negative bacteria, both from clinical samples and from environmental sources.

The production of acylhomoserine lactones (AHL) by planktonic cultures of eight clinical and reference strains of P. aeruginosa was evaluated using two biosensors. The adhesion of the bacteria on a surface (Biofilm Ring Test ®, BFRT), their capacity to develop a biofilm (crystal violet staining method, CVSM), their sensitivity to tobramycin and their secretion of proteases or of rhamnolipids were also measured.

Most Pseudomonas biocontrol strains are associated with the rhizosphere of plants, where they control soil pathogens by antibiosis or competition, and leaf pathogens via induced systemic resistance.

Based on their activity, Pseudomonas biocontrol strains come in three types.

Abstract Cathodic protection (CP) is known as a reliable method to protect steel from corrosion. However, the influence of CP on biofilm formation and maturation is not well known. There are three possible effects of CP on biofilm formation and maturation. Those are: 1) deprivation of anchorage sites for bacterial adhesion, 2) increase of electrostatic repulsion between the steel surface and negatively charged bacteria, 3) elimination of bacteria in the biofilm by increasing pH. To investigate these possible effects of CP on biofilm, carbon steel coupons were immersed in artificial seawater wi

To mitigate this risk, prophylactic antimicrobials are often required, further exacerbating the proliferation of antibiotic resistance.
