EXPERIMENTAL MODEL OF A BACTERIAL AEROSOL IN THE DUST PHASE (EKSPERIMENTALNAYA MODEL PYLEVOI FAZY BAKTERIALNOGO AEROZOLYA)
Abstract
Methodology for setting up experiments with bacterial aerosol in the dust phase was developed. For this purpose sterilized dust was infected with a dense suspension of the white staphylococcus in a physiological solution and then dried. In dispersing 20 or 30 mg of bacterial dust in a chamber of a 250 liter capacity a fairly stable aerosol was obtained, its presence could still be detected 6-8 hours later. A shortcoming of the method is the rapid dying off of the white staphylococcus in artificially infected bacterial dust, as a result of which it is no longer fit for use in experiments at the expiration of 5-7 days or, more rarely, after 7-9 days. When bacterial dust is dried by the lyophilization method, it can be used for experimental purposes for an extended time. In storing lyophilic dust at 2-4C it can remain fit for serial experiments over 35 days, and when maintained at room temperature or at 37C - over 20 days.
