Legionella pneumophila serogroup 1
-
Because of a limited number of reports, we aimed to investigate the clinical characteristics of patients with Legionella pneumonia due to non-Legionella pneumophila serogroup 1 and the diagnostic usefulness of the six-point scoring system for such patients compared with patients with pneumonia caused by L. pneumophila serogroup 1.

Two modi®cations of 5-acetimidoylamino-7-acetamido-3,5,7,9-tetradeoxy-D-glycero-D-galacto-non-2-ulosonic acid (5-N-acetimidoyl-7-N-acetyllegionaminic acid) in the O-chainpolysaccharide (OPS) of theLegionellapneumophila serogroup 1 lipopolysaccharide (LPS) concern N-methyla-tionof the 5-N-acetimidoyl group in legionaminic acid. Both N-methylated substituents, the (N,N-dimethylacetimidoyl) amino and acetimidoyl(N-methyl)amino group, could be allocated to one single legionaminic acid residue in the long-and middle-chain OPS, respectively. ...

Previously, a phase-variable epitope was detected in the virulent wild-type strain RC1 of Legionella pneumophila serogroup 1 subgroup OLDA using a lipopolysaccharide-speci®c monoclonal antibody, mAb 2625 [LuÈneberg, E., ZaÈhringer,U.,Knirel,Y.A., Steinmann,D.,Hartmann,M., Steinmetz, I., Rohde, M., Kohl, J. & Frosch, M. (1998) J. Exp. Med.188, 49±60]. In the present study, an isogenic mutant strain, termed 5215, was constructed by deletion of genes involved in the biosynthesis of the mAb 2625 epitope....
