Predicted duration of detection of (a) Dichelobacter nodosus and (b) Fusobacterium necrophorum on foot swabs from 17 sheep with footrot in Study 2. Predicted duration of detection in weeks (black circles) and associated 95% confidence interval (error bars) from mixed effects Poisson regression models. H/H = healthy foot, all 4 feet of sheep healthy; H/D = healthy foot, at least one other foot of the same sheep diseased with footrot; D = diseased with footrot. ***p < 0.001; **p < 0.01. Significance levels obtained from mixed effects Poisson regression models.
