*First letter of isolate name indicates building type/location: H, hospital; R, residence; W, school using well water; P, large public building. Second letter indicates sample collection location; H, hot water tap; C, cold water tap; D, water heater drain valve; S, shower. Numerals 1–10 indicate clinical strains. ND, not determined because of lack of L. pneumophila–specific alleles or insufficient genome coverage; ST, sequence type.
