Morphology Coxiella
CELLULAR  
Staining Short rods, usually 0.2-0.4 um by 0.4-1.0 um, resembling organisms of the genus Rickettsia in staining properties, dependence on host cells for growth, and close natural association with arthropod and vertebrate hosts. Grows preferentially in the vacuoles of the host cell (rather than in the cytoplasm or the nucleus as do the species of Rickettsia). Unlike Chlamydia, Coxiella does not prevent the formation of phagolysosomes. Grows well in the yolk sac of chicken embryos, where it undergoes a cycle of development which includes formation of an endospore-like body. Has high resistance to chemical agents and elevated temperatures that generally kill Rickettsia species. Although axenic growth has not been obtained, outside the host Coxiella metabolizes glutamate, glucose, and other substrates, provided the pH is low. This property may reflect an adaptation to the environment of the phagolysosome. The distribution in ticks and various mammals is worldwide and infection is particularly prevalent in cattle, sheep and goats. Etiological agent of the aerosolborne human disease Q fever. The mol% G + C of the DNA is 43 (chemical analysis; Smith and Stoker (1951).
