Most UTIs are caused by uropathogenic (UPEC), whereas causes a large portion of non-UPEC UTIs. Both bacteria express type 1 pili tipped with the mannose-binding FimH adhesin critical for UTI pathogenesis. We generated and biochemically characterized 33 murine monoclonal antibodies (mAbs) to FimH. Three mAbs protected mice from UTI. Mechanistically, we show that this protection is Fc independent and mediated by the ability of these mAbs to sterically block FimH function by recognizing a high-affinity FimH conformation. Our data reveal that FimH mAbs hold promise as an antibiotic-sparing treatment strategy. | |||||||||||||||
