A study based on bulk tank milk samples from 100 randomly selected dairy herds was performed to estimate the prevalence and geographical distribution of antibody positive dairy herds. Using the CHEKIT Q-Fever Antibody ELISA Test Kit IDEXX the study demonstrated a prevalence of 59 antibody positive herds 11 antibody intermediate herds and 30 antibody negative herds based on the instructions provided by the manufacturer. The geographical distribution does not indicate a relationship between the regional density of dairy farms and the prevalence of antibody positive dairy farms. The result supports the hypothesis of an increase in the prevalence of positive dairy herds compared to previous years. Findings The bacterium Coxiella burnetii is a zoonotic agent and infection may cause Q fever in man and in animal species. The bacterium has been detected in a large number of animal species and with cattle sheep and goats as being the most common reservoirs 1 . C. burnetii antibodies have been detected within cattle sheep and goat herds in many countries of the world. Thus selected publications that are valued as giving reliable estimates of the respective target populations reported a prevalence of antibody positive herds at 67 of Ontario dairy herds 2 28 of Ontario sheep flocks 3 21 of dairy herds in England and Wales 4 and more than 50 of Dutch dairy herds 5 . The prevalence of PCR positive herds was 40 of northern Italian dairy herds 6 and 22 of Basque dairy sheep herds 7 . Until recently C. burnetii was .
