Q fever is caused by the '''gram negative, intracellular [[Rickettsiales |rickettsial]] [[Bacteria |bacterium]]''', ''Coxiella burnetii''. It causes '''respiratory''' and '''reproductive''' disease in animals and is an important '''zoonosis'''. The organism targets the '''[[Macrophages |macrophages]]''' of the host.

''C. burnetii'' is transmitted by many species of '''[[Ticks |tick]]''', including  [[Amblyomma spp.|''Amblyomma spp]], [[Ixodes spp.]]'' and ''[[Dermacentor spp]]''. It has two interacting cycles of development involving small and large cell variants. Both are infectious.

The organisms can survive for '''long periods outside of a host'''; >586 days in tick faeces and months or years in the environment.
