Coxiella burnetii. False-colour transmission electron micrograph (TEM) of the rickettsia-like bacteria Coxiella burnetii. Highlighted is the endospore of the bacteria, which is a structure formed by bacteria during unfavorable conditions that contains dna and a small amount of cytoplasm. Coxiella burnetii is the cause of an influenza- like febrile illness known as "Q" fever. It is highly infectious, usually including patchy pneumonic consolidation. Hepatitis & endocarditis may also occur. Q fever is transmitted to humans via sheep, goats and cattle. Human infection is by inhalation of dust or droplets contaminated from the excreta of infected animals, or by ingestion of infected milk. Treatment is with antibiotic drugs.
