#MicrobiologyMonday: Bacteria swarm, but DYK they also "swash"? This flagella-independent movement is tied to fermentation: as cells ferment sugars, they create local osmolarity gradients, which generate a wave of fluid driving expansion. #JBacteriology: asm.social/2Gh

P. aeruginosa-secreted 2-heptyl-4-quinolone N-oxide (HQNO) inhibits S. aureus respiration, resulting in manipulation of membrane/cytoplasm redox status and increasing transcription of genes utilized for fermentation to promote survival. #JBacteriology: asm.social/2Ff
Proposed model for SrrAB regulation by Rex. P. aeruginosa-produced HQNO inhibits dioxygen respiration in S. aureus, stimulating the histidine kinase SrrB, which alters the titers of phosphorylated SrrA. SrrA then represses srrAB transcription and increases the transcription of genes utilized for fermentative and anaerobic growth. This exacerbates a fermentation phenotype and increases the ratio of NAD+ to NADH. The increased abundance of NAD+ binds to Rex, increasing its affinity for the operator of srrAB and repressing its transcription. Created in BioRender. https://BioRender.com/x36momp.

#MicrobiologyMonday: California's Salton Sea, the state's largest lake, is drying up. Studies in mice show that dust collected near the lake alters lung microbiomes and triggers more inflammation than dust from areas farther away. #mSphere: asm.social/2Fc
Map of Salton Sea and dust collection sites. Wister (red) is located <2 mi from the eastern edge of the Salton Sea. Palm Desert is located approximately 26 mi northwest from the Salton Sea. Dust material from Boyd Deep Canyon was used in previous host pulmonary inflammation studies (18) and is a site located approximately 20 mi northwest from the Salton Sea. The map was made using Google Earth.
