Comparison of the simulated and the observed distributions of the prevalence in Mycobacterium avium subsp . paratuberculosis (Map) infected adults in infected dairy cattle herds. The simulated distribution corresponds to runs of a Map spread model within a dairy cattle herd, the mean prevalence from year 5 to year 9 since Map introduction in the herd (t = 0) being calculated for each run still infected. The observed distribution is based on individual life long determined statuses in 59 dairy herds at enrolment in a paratuberculosis control program in France, before any control measure is implemented.
