- A hospital warm water system was monitored for the prcsence and distribution of lcgionellac. Subtyping of ten scletled Legionella pneumophiltl isolates. originating from four different sites in the system by using serogroup spccific antisera in an indircct immunofluorcscence tcst, rcvcalcd that nine of the tcn isolatcs belonged to scrogroup 6, while the remaining one was serogroup I 0. Two monoclonal antibodics (mAbs) spccific for a subgroup of serogroup 6 strains were further used for characterization. None of the strains reactcd with theseA hospital warm water system was monitored for the prcsence and distribution of lcgionellac.

Two monoclonal antibodics (mAbs) spccific for a subgroup of serogroup 6 strains were further used for characterization. None of the strains reactcd with these mAbs. Genome analysis by elaborating Not I profiles using the pulscd field gel electrophoresis (PFGE) technique revealed that nearly all serogroup 6 isolates dcrived from different sites, including a new building connected hy a ring pipe. wcrc identical according to restriction fragment pattems. The patterns were distinguishable from those of the two L. pnewnophi/a serogroup 6 rcfcrencc strains, and ftom that of thc L. pneumophila scrogroup 10 isolate. These data arguc for a relatively homogeneaus L. pneunwpltila serogroup 6 population in the entire watcr system.…
