We’re hiring! Join the Weber Lab at the University of Iowa to study Chlamydia effector biology, centrosome regulation, vesicular trafficking, and innate immunity. Please share!
Out Now! Local peptidoglycan composition defines division site selection in Streptococcus pneumoniae #MicroSky
Exciting research here on the development and lab evaluation of #CRISPR #POC tests for #STIs (chlamydia, gonorrhea, syphilis, HSV 1 /2) Also very interesting they could detect S91F to predict cipro resistance in #gonorrhea POC tests for STIs can be game-changers in many settings #STIsky #IDsky
The #WHO just released recommendation of #doxyPEP for #STI prevention among MSM and transgender women Monitoring of #AMR also recommended Research gaps still remain, including long-term impacts on AMR/microbiome and effectiveness in different settings www.who.int/teams/global... #STIsky
This is a great @cidjournal.bsky.social supplement for all you #gonorrhea, #STI, and #AMR enthusiasts. Or for anyone who’s heard about drug-resistant gonorrhea and wants to learn more. Will link articles in 🧵 below - check it out and share! #openaccess #IDsky #STIsky bsky.app/profile/carb...
Wishing a happy and successful year to all of you
I'm convening a session at ASM Microbe 2026 on vaginal infections. Come learn about the great recent advances in research on Gardnerella, Sneathia, Group B Strep, and Candida infections. #ASMicrobe invt.io/1bxbqiyuh8c
Excited to share my latest postdoctoral work in the Shen Lab at Tufts! In this study, we follow up on an exciting finding by former grad student @shailab.bsky.social that C diff uses its Class A PBP (PBP1) to drive cell division (unlike previously studied bacteria)! journals.plos.org/plosgenetics...
Dr. Cole's presentations at the Neisseria meetings were delightful. So sorry he is gone.
We mapped the whole human fallopian tube in 3D and at single-cell resolution via our CODA workflow. More about this work here: biorxiv.org/content/10.1...

It is with deep sadness that we share the passing of Professor Jeff Cole. An esteemed academic, Jeffs research on bacterial adaptation to oxygen and nitrosative stress made a lasting impact on the field. He mentored nearly 60 doctoral students, our thoughts are with his family, friends & colleagues
