For invading bacteria that have figured out how to scavenge iron from their hosts, it’s a fine place to grow and reproduce. And for millions of women a year, that means painful, burning, potentially dangerous urinary tract infections. Now, in an ironic twist, scientists prevented UTIs in mice by vaccinating them with the same molecules that the bacteria usually use to grab iron and fuel their growth. They caution that a human UTI vaccine based on the approach is still years away. But the success of vaccination with the small iron-grabbing molecules, ie siderophores, paves the way for further research.

The same team previously reported success in preventing UTIs using a vaccine made of proteins from the bacteria, called uropathogenic Escherichia coli or UPEC...
