Expanding the LuxR-type receptor functional repertoire: Protein-protein interactions in quorum sensing regulation Quorum sensing (QS) enables bacteria to coordinate gene expression in response to population density, with LuxR-type transcription factors playing a central role in this process for many Gram-negative...

A true labor of love for @calebmallery.bsky.social is out now in PLOS Pathogens: a review article where we highlight current and emerging examples of key protein-protein interactions with LuxR-type receptors that control community behaviors and pathogenesis.

Characterization of β-lactam resistance in dual-species biofilms of Pseudomonas aeruginosa and methicillin-sensitive Staphylococcus aureus Polymicrobial biofilms are frequently associated with chronic infections and are highly tolerant to antibiotic treatment. Given that β-lactam antibiotics are the most prescribed antibiotics worldwi...

The disputed identity of Pseudomonas putida KT2440: when taxonomists rename your favorite microbe | mBio Names matter; they are not mere labels. They operate as anchors of memory, social coordinates, and references of collective identity. When a name becomes established through long-term use and broad ad...

A must read! The constant and often irrational renaming of microbes is out of control, and bad for microbiology and microbiologists.
