Available control measures for Q fever in sheep
Q fever is a worldwide zoonosis caused by Gram-negative bacteria, Coxiella burnetii. This antropozoonosis is characterized by a wide spectrum of hosts and vectors. Primary role of domestic animals as reservoirs of human infections emphasizes the accurate prompt detection of Q fever in domestic anima...
