Figure 5From: Modelling transmission of Mycobacterium avium subspecies paratuberculosis between Irish dairy cattle herdsDistribution of herd characteristics among all herds, those escaping infection, and those always infected. Herd characteristics of all herds in the metapopulation (n = 13 353, striped), herds that have a probability > 90% of escaping infection (1629 herds, green), and herds that consistently became infected during the 10-years simulation period (3862 herds, blue). Herd characteristics considered: average in-degree (A), average out-degree (B), average in-strength (C), average out-strength (D), average herd size (E), and average number of males purchased (F). For the definition of the probability of a herd escaping infection or becoming infected see text.Back to article page
