Fig. 6

Fitting parameters of transmission of M. bovis from environmental sources. The figure shows the dependence of model fit on the number of holdings exposed to M. bovis in environmental reservoirs and the rate of transmission of M. bovis from an environmental reservoir to local cattle. All other parameters were kept at their baseline values. Low values of the measure of fit indicate combinations of the parameter values at which the model matches observations relatively closely. Measures of fit are based on 10 simulations per point. The horizontal, transmission rate axis is plotted on a log scale but labelled with back transformed values
