Oxalobacter formigenes colonization normalizes oxalate excretion in a gastric bypass model of hyperoxaluria

In our model, OXWR lowered urinary oxalate by luminal oxalate degradation in concert with promotion of enteric oxalate elimination. Trials of O. formigenes colonization and low-fat diet are warranted in calcium oxalate stone formers with gastric bypass and resistant hyperoxaluria.
