#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.

#MicrobiologyMonday: Staphylococcus aureus divides by building a septum and then splitting into 2 daughter cells. But how is septum formation coordinated with cell scission? Research in #mBio suggests cell wall mechanical stress could play a role: asm.social/2Eq
Mechanical stress in the S. aureus cell wall during the cell cycle. (A) As the cell cycle progresses, stress at the equator decreases due to growth of the septum while the stress remains unchanged at the pole. The stress distributions shown here were calculated for MSSA with cell volume 1.22 µm3, thickness 20 nm, turgor pressure 2 MPa, and septum relative stiffness 1.2. (B) Graphical representation of the changes in circumferential stress at the cell pole and equator as septum synthesis progresses. Here, septum progression is defined as (a − b)/a, where a is the cell radius and b is the septum aperture size, which decreases as the septum is formed (note that a and b are defined for the unpressurized cell; see Supplementary Information, Section II).

Effects of CRISPR activation of PARPs on IAV replication. HEK293-dCas9-VP64-MPH stable cells were transfected with a combination of three lenti-sgRNA-MS2 targeting each of PARPs or non-template control sgRNA (NTC) (100 ng), the IAV firefly luciferase reporter plasmid vNP‐luc/pHH21 (20 ng), and pRL‐TK Renilla plasmid (5 ng) for 24 h The cells were then infected with influenza 2009 pandemic clinic isolate A/Oklahoma/3052/09 (pdm/OK/09) H1N1 at an MOI of 0.05 for 48 h. Firefly luciferase activity was normalized to pRL‐TK Renilla luciferase activity. The results are expressed as a ratio to NTC‐transfected cells. Data are the mean ± SE of three independent experiments.
