82-03: Concentration, Serotypic, Profiles and Infectivity of Legionnaires'The concentration and serotypic profiles of Legionnaires' Disease Bacteria (LDB) in water of industrial cooling towers from various areas of the continental United States was determined. The characteristics of the LDB populations were compared to the biocide treatment and type of tower fill. Effects of cleaning and altered biocide treatment on LDB populations were assessed. The ubiquity of the LDB in both ambient control and cooling tower water was
