Characterization of carABpyrB operon and role of pyrE in Francisella novicida biofilm

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Pyrimidine biosynthesis links metabolism to biofilm regulation in Francisella novicida. During nutrient limitation, reduced pyrimidine availability shifts metabolism from uracil salvage to de novo synthesis, increasing biofilm formation. Mutants in carABpyrB exhibit uracil‐dependent growth defects and elevated biofilm:growth ratios, revealing ...

Multifaceted Suppression of Staphylococcal Virulence Phenotypes: In Vitro Study of a Cellular Status With Reduced Agr Activity and Impaired Biofilm

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Finding of in vitro S. aureus status with reduced Agr activity and impaired biofilm. ABSTRACT Anti‐quorum sensing (QS) therapy has been focused on to reduce the virulence of pathogenic bacteria. However, there is a risk that suppression of the staphylococcal QS Agr system might promote biofilm formation.
