Substantial production and financial losses are suffered throughout the goat industry annually to this zoonotic disease. And in humans, while most people who become infected only suffer from. Q fever or query fever is a disease caused by infection with Coxiella burnetii, a bacterium that affects humans and other animals. This organism is uncommon, but may be found in cattle, sheep, goats, and other domestic mammals, including cats and dogs.The infection results from inhalation of a spore-like small-cell variant, and from contact with the milk, urine, feces, vaginal mucus, or semen.

Q fever represents 3%-5% of all cases of endocarditis [3, 4]. Endocarditis usually occurs in patients with previous valvular damage or those who are immunocompromised [2, 5-8]. Because symptoms of Q fever endocarditis are not specific, diagnosis is often delayed, which results in an increased mortality rate Q fever is a ubiquitous zoonosis caused by Coxiella burnetii. The most common animal reservoirs of this organism are cattle, sheep, goats, and cats [1, 2].Infected animals excrete the bacterium in milk, urine, feces, and birth by-products [3, 4-5], especially the placenta, which can contain up to 10 9 organisms per gram of tissue [].At the time of delivery, such infected placenta may.

Q fever is a common zoonosis (infection that could transmit from animals to humans), caused by Coxiella burnetii. Natural reservoirs include several domestic and wild animals, most of which show no signs of disease (although infection can cause abortions). Due to the high resilience in the environment of Coxiella, humans. Studies on Q fever in children <5 years of age are scarce, especially with respect to sub-Saharan Africa. The only available study from Niger reports a seroprevalence of 9.6% ( 2 ). Throughout Africa, prevalence of Q fever in adults shows considerable variability and is highest in countries with prominent stockbreeding ( 3 ) Key words: Coxiella, epidemiology, Q fever, serology, zoonoses.
