Eighty herds were initially voluntary enrolled in the study and a bulk milk sample from each farm was assayed by ELISA for </span><em><span lang="EN-US">C burnetii </span></em><span lang="EN-US">antibodies. According to antibody titre, herds were classified into 5 categories: negative and grades 1,2,3 and 4 (ascending scale). To assess the prevalence within farms, two herds from each category were selected and blood samples were collected for antibody assessment. In these herds, some reproductive indices were compared between farms; in addition, comparisons were made in paired seropositive and seronegative animals from one grade 3 herd. Twenty three herds (35%) were found positive, 21 being in categories 3 and 4. The prevalence of seropositive animals between herds varied from 4.9 to 46.3%, even from farms initially characterized as negative, some positive animals were detected. Between farms, no differences were detected in the abortion rate or in the mean number of artificial inseminations (AI) per pregnancy. Some differences were found in other reproductive indices that were impossible to be biologically interpreted under the light of </span><em><span lang="EN-US">C. burnetii </span></em><span lang="EN-US">level of infection. From the results presented here, we infer that </span><em><span lang="EN-US">C. burnetii </span></em><span lang="EN-US">infection is likely </span><span lang="EN-US">asymptomatic in dairy cows causing minimal -if any- economic losses to farmers. However, since the disease is a zoonotic one, its spread can easily occur, a systematic surveillance, in all ruminant species, for the restriction or eradication of the disease should be undertaken in national level.</span></p>}, number={4}, journal={Journal of the Hellenic Veterinary Medical Society}, author={DOVOLOU (Ε.
