Detection of Coxiella burnetii by PCR in tank milk from cattle herds with reproductive problems in France

Summary

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.
