Abstract: The study aimed to determine the frequency of Coxiella burnetii in sheep flocks located in some states of Mexico. The analysis of 5.552 serological samples was carried out in 317 flocks in 61 municipalities of seven states of the Mexican Republic. Serology was performed with a commercial ELISA-kit and the frequency of C. burnetii seropositive animals was used to calculate the real prevalence per animal and flock level by state. The apparent prevalence of C. burnetii by flock in each state was: Sonora 50%; Chiapas 35.1%; Queretaro 28.1%; Hidalgo 28.3%; Tlaxcala 27.8%; Chihuahua 27% and the State of Mexico 10.9%. The real prevalence by state was: Tlaxcala 13.2% (IC95 10.4-16.0%); Querétaro 12.6% (CI95 10.4-14.9%); State of Mexico 12.4% (CI95: 10.0-14.8%); Chihuahua 11.8% (IC95: 9.7-13.9%); Hidalgo 11.0% (IC95: 8.9-13.1%); Chiapas 7.9% (IC95: 5.8-10.1%) and Sonora 2.5% (IC95: 1.5-3.4%). Although, Q-fever is considered an exotic disease in Mexico, this study evidenced the presence of antibodies against Coxiella burnetii in sheep flocks located in seven states of Mexico.
