ABSTRACT The purine-derived signaling molecules c-di-AMP and (p)ppGpp control mecA/PBP2a-mediated β-lactam resistance in methicillin-resistant Staphylococcus aureus (MRSA) raise the possibility that purine availability can control antibiotic suscept

A Staphylococcus aureus strain deleted for the c‐di‐AMP cyclase gene dacA is unable to survive in rich medium unless it acquires compensatory mutations. Previously identified mutations were in opuD, encoding the main glycine‐betaine transporter

Ultraviolet (UV) irradiation is an emerging strategy for controlling the formation of undesired biofilms in water desalination facilities using reverse osmosis (RO). However, most studies examining these pretreatments are limited as they have been co

Improved easy-to-use diagnostic tools for infections are in strong demand worldwide. Yet, despite dramatic advances in diagnostic technologies, the gold-standard remains culturing. Here we offer an alternative tool demonstrating that a bacterial bios

2-Aminoacetophneone (2-AA) is a volatile molecule produced in high amounts by the opportunistic pathogen Pseudomonas aeruginosa. We have previously shown that 2-AA activates the quorum sensing (QS) LuxR receptor of Aliivibrio fischeri. In the present

Arthrobacter sp. 4Hβ, capable of degrading and utilizing high concentrations of p-nitrophenol (PNP) as sole carbon, nitrogen and energy source, was isolated from agricultural soil by a simple enrichment culture. Bacterial growth was accompanied by P

In this study we identify a volatile compound produced by Pseudomonas aeruginosa, which can specifically activate the LuxR quorum-sensing response regulator of Vibrio fischeri. Comparative gas-chromatography analysis between P. aeruginosa wild type a

In the current study we examined the impact of thread filtration using an automatic microfiber filter on Lake Kinneret water quality and as a new application to control biofouling over time. We found that automatic microfiber filtration (AMF) reduced
