    Abstract: The study aimed to determine the frequency of
<i>Coxiella burnetii</i> 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
<i>C. burnetii</i> seropositive animals was used to calculate the
real prevalence per animal and flock level by state. The
apparent prevalence of <i>C. burnetii</i> 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%); Quer&eacute;taro 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
<i>Coxiella burnetii</i> in sheep flocks located in seven
states of Mexico.
