Which organism is primarily responsible for Q fever?

Coxiella burnetii is the organism primarily responsible for Q fever, which is an infectious disease that can cause severe flu-like symptoms and pneumonia. This bacterium is known for its resilience in the environment, surviving at high temperatures and in various ecosystems, particularly in livestock. It is typically transmitted to humans through inhalation of contaminated aerosols from infected animals, especially sheep, goats, and cattle, as well as through consumption of unpasteurized dairy products.

Q fever is characterized by a sudden onset of fever, chills, and fatigue, sometimes leading to more severe complications such as pneumonia or hepatitis. The identification of Coxiella burnetii as the causative agent of Q fever is critical for appropriate clinical management, including the necessity for specific diagnostic tests and treatment options. This recognition also emphasizes the importance of public health measures in controlling zoonotic infections and preventing outbreaks in humans.
