Background Mycoplasma (M.) bovis causes in cattle, among other diseases, mastitis. The dairy cattle population in Denmark had an increase in atypical clinical outbreaks of M. bovis over the past years. An important prerequisite to the implementation of an effective control program is to determine the geographical distribution of M. bovis. The maps show the location of the clusters of M. bovis infected herds, while the inserts (K- function) indicate global clustering of cases around a radius of 70 km (app), in each round. (*)There was no clustering in the second round.  The clusters are in areas with high herd and cattle density. * All Dairy herds were sampled Acknowledgements: • Danish Milk Levy fund who funded the sampling • SEGES who provided the data
