Molecular Oral Microbiology, EarlyView.ABSTRACT Porphyromonas gingivalis is a key pathogen in periodontitis, with secreted proteases as major virulence factors. We developed a screening method to generate and identify P. gingivalis mutants with elevated protease activity. Mutations were induced using the mutagens 2,6‐diaminopurine (2,6‐DAP) or ethyl methanesulfonate (EMS), and the ...

Regulation of bistability in the std fimbrial operon of Salmonella enterica by DNA adenine methylation and transcription factors HdfR, StdE and StdF [PDF]
, 2019 Bistable expression of the Salmonella enterica std operon is controlled by an AND logic gate involving three transcriptional activators: the LysR-type factor HdfR and the StdE and StdF regulators encoded by the std operon itself.

How Salmonella Works Under Osmotic and Desiccation Stresses
Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT Salmonella remains one of the leading threats in foods with reduced water activity, where it can survive for long periods and cause outbreaks. Its persistence stems from a wide array of adaptive strategies shaped by the selective pressures imposed by low‐moisture foods.

MicrobiologyOpen, Volume 15, Issue 2, April 2026.C. anisata fruit extract and its compounds demonstrated potent broad‐spectrum antimicrobial activity, notably against Klebsiella pneumoniae (MIC 0.625 mg/mL; MLC 2.5 mg/mL) and Candida albicans (MIC 0.0781 mg/mL; MLC 0.625 mg/mL). The findings highlight promising bactericidal and fungicidal potential of stigmasteryl 3‐palmitate and phellopterin against
