PolysacDB ID1516
Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeKlebsiella pneumoniae Friedlander 201   (NCBI Taxonomy)   (Drugpedia)
Basic StructureO-1 side chain of the LPS is proposed to contain a disaccharide repeat unit consisting of [-α-D-Galp-(1->3)-β-D-Galf-] (1->4), where Gal is galactose
BCSDB StructureN/A
Proposed functionsThese major cell surface antigens play important roles in the ability of the bacterium to evade host cell defenses
Antigenic Nature used to produce antibodiesFormalinized whole cells
Carrier NameNil
Conjugation MethodNil
AntibodiesMab Ru-O1
Antibody type and classIgG2b
Assay SystemELISA and invivo protection studies
Cross-reactivityThis Mab cross-reacted with LPS prepared from strains belonging to the O1 serogroup, O19b antigen of E. coli, which has been shown to be immunologically identical to Klebsiella O1 and O6 and O8 antigens
Proposed epitopesO1 antigen seems to bea part of the epitope
IEDB EpitopeN/A
Proposed UtilityThis Mab showed invivo protection and significantly reduced bacterial dissemination to various organs as well as macroscopic and histologic pulmonary alterations
