Whether on simple criteria (clinical, macroscopic analysis of reproductive performance), or detailed analysis of reproductive performance over a season, Coxiella burnetii was detected by PCR on bulk tank milk in 1 farm out of 5 to 1 farm out of 2, depending on the recruitment method of the farms.
A bulk tank milk PCR can be a good first orientation analysis to judge the relevance of further investigations to confirm the involvement of Coxiella burnetii in reproductive disorders in dairy cattle.
