Outline of Final Research Achievements

The possibility of preventing the recurrence of bovine digintal dermatitis (PDD) and re-infection of Treponema species was demonstrated by using the combined treatment of application of allyl isothiocyanate (AITC) and hoofing. Microbiome analysis indiated that T. medium-like and T. denticola-like isolates showed the possibility of playing an important role in PDD deformity. We developed three real-time PCR and four LAMP assays that can specifically detect and distinguish three different Treponema species at both genus and species levels.
