Studies of the loss of viability of stored bacterial aerosols. II. Death rates of several non-pathogenic organisms in relation to biological and structural characteristics

For several decades bacteriologists and epidemiologists have been interested in the survival of micro-organisms in the airborne state. Studies by many investigators, recently summarized by Wells (1955), have produced data concerning certain aspects of bacterial survival or death, but the information has not generally sufficed to permit quantitative analysis when a fluid environment was changed in the airborne state.
