Q fever is caused by Coxiella burnetti, a gram negative pleomorphic bacillus.
Ticks and vertebrates(goats, sheep, and less commonly birds) are natural reservoirs.
Symptoms typically: fever, penumonitis, severe headache and photophobia.
Meningitis, hepatitis and thromboses are seen in more-severe disease.
Diagnosis: PCR, culture of blood or body tissue.
Treatment: usually self limited, doxy if needed.
