Effect of Diluent and Relative Humidity on Apparent Viability of Airborne Pasteurella pestis

摘要: Airborne Pasteurella pestis (A-1122) at low humidities [20 to 50% relative humidity (RH)] exhibited exponential decay when either 1% peptone or Heart Infusion Broth (HIB) was used as the diluent in viable assay system. At higher RH values (65 and 87%), however, adversely affected viability assay. In contrast, HIB remarkably effective demonstrating a number of cells aerosols held high values. Similarly, with diluent, were shown contain during 90 min observation; peptone, not detectable after 20 airborne state.
