E. coli can spread as quickly as swine flu, new research reveals. 🦠

For the first time, scientists can predict the rate at which gut bacteria pass between people — a major step towards tackling antibiotic-resistant infections.

Advanced disease modelling shows some gut bacteria can spread as rapidly as viruses
Experts can now predict the transmission rate of a bacterial E. coli infection in the same way as they can for viral pandemics, which can help battling treatment-resistant infections in the future.

One for the surgeons today. Many vets perform surgery on a regular basis, so understanding infection prevention and antimicrobial prophylaxis is key in prevent surgical site infections and promoting responsible antimicrobial use!

🐶🐱 Companion animals need #AntimicrobialStewardship too! In our new SR/MA (led by Dr. Fiona Emdin), we examined short vs. long antibiotic durations for UTIs in dogs & cats.📉 Pooled RR for cure = 0.55 (95% CI: 0.23–1.27), very low certainty.

Was thinking of a comparative article on beta-lactams use for pyelonephritis as NICE recommends PO cefalexin but upon reading the literature, I can't make it make sense 🤷 EUCAST only has a UTI breakpoint, PKPD suggests poor empirical choice, but clinical studies seem ok.
