Incidence of Pseudomonas aeruginosa serogroups in drinking water: use of serotyping in the control of water supplies.
From 26,568 drinking water samples collected in the years 1977-1981 from deep well supplies in Csongrád county, Hungary, 1269 Pseudomonas aeruginosa strains were isolated. The most frequent serogroups (Lányi-Bergan scheme) were O6 (9.5-69.2%), O1 (5.5-35.5%) and O9 (2.2-36.2%). Predominance of a given serogroup varied with, and was characteristic of geographic areas of the county, water plants and distribution systems. Bacteriological monitoring has shown that serotyping of P. aeruginosa may be useful for evaluating the mechanical condition of the water supply.
