Survival of the Q fever agent Coxiella burnetii in the phagolysosome

Trends Microbiol. 1994 Dec;2(12):476-80. doi: 10.1016/0966-842x(94)90651-3.

Abstract

The Q fever agent, Coxiella burnetii, thrives in the acidic environment of the phagolysosome of the host cell. How this obligate intracellular agent manages to survive within this hostile milieu is unknown; however, several of its enzymes may eliminate or prevent the formation of toxic oxygen metabolites by the host cell. Also implicated as virulence factors are its surface lipopolysaccharide and plasmids.
