Our review on recent advances in #PhageTherapy against Klebsiella pneumoniae is out!
We analyze KP-phage interactions from an eco-evo perspective, summarize many lab and clinical trials, and discuss novel approaches like genetic engineering & machine learning.

🔬 The spotlight continues!
We’re excited to introduce the next incredible member of the #PittsburghPhageProgram team — meet Dr. @dariavantyne.bsky.social, whose work is helping push the boundaries of what’s possible in #phagetherapy. #InfectiousDiseases #P3 #VanTyneLab

Behind every patient story, every discovery, and every #phage, there’s a dedicated team making it happen.
Over the next few weeks, we’re excited to introduce the people who power the #PittsburghPhageProgram — starting with Dr. Ghady Haidar.🧫✨

Shoutout to @dariavantyne.bsky.social, our Head of Phage Biology and Discovery, for her leadership in #phagetherapy. P3's latest clinical impact was given the spotlight in Contagion Live! Read more on how phage therapy is transforming treatment options: 🔗 tinyurl.com/Contagion-Live

Finally, we wondered whether the strain replacement we observed at our hospital was a widespread phenomenon by examining over 15,000 publicly available VREfm genomes. We found that what is happening at UPMC is also happening all over the world. Global genomic surveillance for the win!
dariavantyne.bsky.social
To test whether bacteriocin T8 could help VREfm colonize the intestine, we phoned a friend @joeyzacks.bsky.social. The Zackular lab performed a mouse colonization study, which showed that bacteriocin T8 provided a strong competitive advantage in the mammalian gut.
dariavantyne.bsky.social
We observed large-scale strain replacement just in the 6 years of our study, and Emma figured out that this was likely due to production of a bacteriocin called T8, which is carried on a plasmid, kills enterococci, and was previously studied as a probiotic for the treatment of intestinal dysbiosis.

In this study, first author @emmamills1.bsky.social took all the genomes collected by EDS-HAT between 2017 and 2022 and asked a simple question: which VREfm lineages are prevalent in the population, and does their prevalence change over time? Spoiler alert: There were big changes!
dariavantyne.bsky.social
We are fortunate to have access to VREfm genomes and isolates from EDS-HAT, a bacterial genome sequencing surveillance program that has been running @upmc.com for almost a decade. EDS-HAT was built to detect transmission (yay @sundermannaj.bsky.social!), but it also enables lots of other studies.

👋 We're the Pittsburgh Phage Program (P3)! Based at Pitt, we advance precision medicine using phages—viruses that kill bacteria. We fight antibiotic resistance through compassionate use & clinical trials.

I remember seeing Dr. O’Brien at seminars around Boston and Cambridge and being wowed at his stature, both physically and in the AMR field. And that was before I knew whose father he was… www.nejm.org/doi/abs/10.1...
