In this study, a dot-blot application was designed to detect Leptospira from the three main clades in water samples. This method allows for the identification of minimal DNA quantities specifically targeted by a digoxigenin-labeled probe, easily detected by an anti-digoxigenin antibody. This approach is a valuable and satisfactory tool for screening purposes.
