Cross-species activation of hydrogen cyanide production by a promiscuous quorum-sensing receptor promotes Chromobacterium subtsugae competition in a dual-species model

This study shows that promiscuous quorum-sensing receptors in Chromobacterium subtsugae allow cross-species activation of hydrogen cyanide production, giving it a competitive advantage in a dual-species model.

Plasmid-encoded H-NS controls extracellular matrix composition in a modern Acinetobacter baumannii urinary isolate

This study shows that plasmid-encoded H-NS in Acinetobacter baumannii represses extracellular matrix components, reducing biofilm formation and virulence.

Efflux pumps in Chromobacterium species and their involvement in antibiotic tolerance and survival in a co-culture competition model

This paper identifies two RND-family efflux pumps in Chromobacterium species that confer antibiotic resistance and enhance competitive survival in co-culture with Burkholderia thailandensis.

The C. elegans CHP1 homolog, pbo-1, functions in innate immunity by regulating the pH of the intestinal lumen

This study shows that the C. elegans protein PBO-1 regulates intestinal pH, which is critical for pathogen defense through reactive oxygen species production.
