Final answer:
Coxiella burnetii causes Q fever, a zoonotic disease primarily affecting livestock workers through inhalation of contaminated aerosols, leading to symptoms such as fever and headache, and can cause severe complications.
Step-by-step explanation:
Coxiella burnetii is the causative agent of Q fever, a highly infectious zoonotic disease. Individuals, especially farmers and those in close contact with livestock can contract Q fever through inhalation of contaminated aerosols. This pathogen primarily affects domesticated mammals such as cattle, sheep, and goats, and its infection in humans can lead to symptoms like high fever, headache, coughing, and in severe cases, pneumonia or endocarditis.
