🎉 New preprint. First piece of work from us looking at how Klebsiella spp. use gut microbiome-associated metabolites present in urine. Very much v1 but we wanted it out for feedback, and to support lead author @devarsh1917.bsky.social as he applies for PhDs. #microSky

Delighted for @mohamedeladawy.bsky.social on the publication of the "big one" from his PhD work. - Largest genome-based study on uropathogens in Egypt. - AMR genes for Pseudomonas, and those associated with meropenem poorly understood. - Prediction databases need better curation. #UTIsky #microsky

We had a few weberviruses isolated and lots of K. pneumoniae strains/genomes but hadn't done anything with them. COVID lockdown meant Sam needed to change the focus of his PhD for a while. This is the result. Nice collaboration with @davidnegus.bsky.social and @halllab.bsky.social, among others.
