Longitudinal shedding pattern of cows. Cows in the top graph are progressing to be a high shedder, while cows in the lower graph are shedding intermittently and low numbers of cfu. Progressors (n = 16) were defined as cows with an increasing cfu of MAP shedding over time. Non-progressors (n = 42) were defined as cows with no increase in cfu of MAP shedding and measurement of no shedding in between measurements with MAP shedding.
