Direct PCR results showing disinfectant efficacy (contact made between hoof knives and BDD lesions). Treponema DNA Positive Samples (%) identified by direct PCR, showing efficacy of three disinfectants (compared to water) for disinfection of hoof knife blades for removal of Treponema genus DNA and DNA from three BDD-associated treponeme phylogroups. Contact was made between the hoof knife blades and the BDD lesions (n = 111)
