Susceptibility of Coxiella burnetii to Chemical Disinfectants

reportActive / Technical Report | Accession Number: ADA226976 | Open PDF

Abstract:

The resistance of Coxiella burnetii to physical and chemical stress is well documented. Compared with vegetative bacteria and other rickettsiae, this hardy microorganism resists elevated temperatures, desiccation, osmotic shock, ultraviolet light, and chemical disinfectants. The environmental stability of C. burnetii is perhaps related to i the sporulation process, which produces endogenous spores and small dense cells, and ii the metabolic dormancy of C. burnetii at neutral pH C. burnetii is very stable and easily transmitted in aerosols. Estimates of infectivity for humans range from 1 to 10 microorganisms. Survival of the microorganisms for long periods in contaminated foods, buildings, and pastures has resulted in human and animal infections.
