People spend loads on #UTI preventions that aren’t truly effective, like D-mannose. £19.99 only buys you a 2-week course. The rest of the products on display were similarly expensive and unlikely to do much. We need better therapies! (See Alt text for source of negative D-mannose RCT) #UTISky

🚨 New preprint 🚨
With two excellent students Shalini Choudhary and Jacob Smith, we started looking at how the metabolic microenvironment of the urinary tract might affect uropathogenic E. coli evolution and response to antibiotics.

MinD is famously known for positioning FtsZ at mid-cell in bacteria
In our study, myself and @iduggin.bsky.social found that MinD homologues in Haloferax volcanii influence the localisation of CetZ1, a homologue of FtsZ and tubulin

Why is preterm birth risk doubled with maternal UTI? It depends on the immune response. We found distinct immune signatures in a UTI-associated preterm birth mouse model. In a human cohort from @AShea_Lab, urine cytokine levels could predict preterm birth. www.biorxiv.org/content/10.1...
Distinct maternofetal immune signatures delineate preterm birth onset following urinary tract infection
