Hypothesis

Can ciprofloxacin and/or E. coli Nissle eradicate IBD associated E. coli in the streptomycin-treated mouse intestine?

Conclusion

Ciprofloxacin effectively eradicated IBD associated E. coli, but E. coli Nissle alone did not, and its introduction after ciprofloxacin treatment allowed some strains to re-colonize.

Supporting Evidence

  • Ciprofloxacin treatment for three days effectively eradicated IBD associated E. coli in mice.
  • E. coli Nissle did not eradicate IBD associated E. coli but resulted in co-colonization.
  • One IBD associated E. coli strain reappeared after treatment with E. coli Nissle.

Takeaway

This study tested if a medicine and a probiotic could get rid of bad bacteria in mice with gut problems. The medicine worked, but the probiotic didn't help on its own.

Methodology

Mice were precolonized with E. coli strains and treated with ciprofloxacin and/or E. coli Nissle, with colonization levels monitored through fecal cultures.

Limitations

The study was conducted in a mouse model, which may not fully replicate human IBD conditions.

Participant Demographics

Mice used were six-to-eight-week-old, outbreed albino female CFW1 mice.
