A major effort finally coming together! Crucial insights into the function of the T6SS, in the gut symbiont Bacteroides. It's also a great example of how collaborative and international research brings people together.

The CDC warns that extensively drug-resistant (XDR) Shigella is on the rise in US. The prevalence of XDR Shigella isolates in US surveillance data rose from 0% during 2011-2015 to 8.5% in 2023. Read more: ow.ly/VXee50YLphl 📷: CDC, Stephanie Rossow

🦠 EMBO Workshop Shigella: from biology to prevention 📅 April 20-24, 2026 📍 Institut Pasteur, Paris Register now ➡️ www.shigella2026.conferences-pasteur.org/home @embo.org @shigellameeting.bsky.social
Shigella was the leading cause of diarrheal disease during World War One; and more than 100 years later, it continues to cause approximately 200 million cases and 216,000 deaths per year around the globe. Shigella is a leading cause of moderate to severe diarrhea in children less than five years of age in low- and middle-income nations, and significant disease occurs throughout Europe and North America due to sexual transmission, food borne and water borne outbreaks, and high incidence in homeless populations. The lack of a licensed vaccine, coupled with alarming increases in antimicrobial resistance, has led the World Health Organization to declare Shigella a priority pathogen for which research into new therapeutics are urgently needed.

Our first effort exploring gut bacteria-extracellular ATP interactions is published! We show that eATP rewires gene expression and physiology in harmless and pathogenic bacteria, impacting production of bioactive metabolites, antimicrobial sensitivity, and virulence.
