New studies reinforce accumulating evidence that spatial structuring can dictate community resilience and reveal that motility and chemotaxis are critical drivers of interspecies competition. @DominiqueLimoli #mBio https://t.co/gwIKuofovy

Excited to see our latest study in print, led by @andreasanchezs_ ! Andrea found P. aeruginosa uses pilus mediated motility to invade and disperse S. aureus biofilms, rendering Sa cells susceptible to secreted Pa antimicrobials. https://t.co/TyMKai4cxf

Check out our newest preprint: P. aeruginosa uses pilus-mediated motility to invade and disperse S. aureus biofilms, rendering Sa cells susceptible to Pa antimicrobials. Without invasion Pa restricts Sa expansion forming dense Sa colonies with altered physiology @asanchezpena_

Very proud to see our most recent manuscript in print. Study led by @kdyarrington in collaboration with @tnshendruk revealing PilJ as a P. aeruginosa type IV pilus chemoreceptor for chemotaxis towards interspecies signals. @IUBiology @UIowaMicrobio https://t.co/GdBStN26p9

I am delighted to share formally that I'm joining Indiana Univ. Micro. in Bloomington as associate professor beginning January '24. My time in Iowa has been incredibly rewarding and I am excited by new opportunities as I embark on this next chapter. Thanks to all for the support!

So proud of @ShelbyEAndersen and Paige McCaslin! Tremendous amount of work went into completing this story. Happy to see this out at IAI! Please check out Shelby's🧵 and paper.

We at #IUMicro are looking to bring in leaders in the field of #microbiomes and #hostmicrobe interaction. Are you an established investigator looking to move to a collaborative, supportive environment? Check us out! #ASMicrobe

Excited about our recent work from my student Chris Geiger supporting a model of the T4P motor PilT, via interaction with PilJ, as key for surface sensing and cAMP signaling. https://t.co/IeMnt0NHNd @m2p2_dartmouth

Iron bioavailability regulates Pseudomonas aeruginosa interspecies interactions through type VI secretion expression

Today we celebrate Dr. Shumin Tan, an associate professor @TuftsUniversity @TuftsGSBS! Dr. Tan's lab studies how Mtb responds to cues from the host environment. They use fluorescent reporters to get single Mtb cell resolution in the granuloma! #WomenInSTEM #WomensHistoryMonth

This multidisciplinary project was led by @GracieW1125 in collaboration with Lizzie Warren, @asanchezpena_, @allisonlhaas, @MicrobioMegan, David Tirrell, and @jbombscientist.

While T6SS are typically interspecies weaponry utilized between Gram negative bacterial species, we find competition sensing allows for T6SS-dependent inhibition of the Gram positive S. aureus, providing P. aeruginosa with a competitive advantage.

Excited to share our newest preprint reporting that P. aeruginosa senses Staphylococcal secreted cytotoxic peptides through “competition sensing” and preempts competitor attack by systematically arming cells with type six secretion systems (T6SS). https://t.co/E1l5FQFeHj

Nutrient stress is a target for new antibiotics @TrendsMicrobiol from @eric_brown_bbs https://t.co/QZaSwmkQw4

Very excited to share our new study on bacterial cellulose secretion: a new look at the longest-studied synthase- and c-di-GMP-dependent EPS secretion system that reveals unexpected Bcs subunit localization for inside-out cytoskeleton-driven regulation https://t.co/J598Opfij1

Best holiday present ever!! Thanks to my incredible lab for the gift of their microscopy images printed on a deck of playing cards. Proud to be training the next generation of microscopists and card sharks!
