PolysacDB ID1118
Carbohydrate NameO-polysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeActinobacillus pleuropneumoniae serotype 1 shope 4074   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe O-polsaccharide structure is as follows :
--6)-α-D-Glcp-(1-->2)-α-L-Rhap-(l-->2)-α-L-Rhap-(1--. which is linked to 1-D-GlcpNAc chains on its rhamnopyranosyl residue via 1-->3 linkage.
BCSDB StructureN/A
Proposed functionsLPS is an important virulence factor. It molecule plays an important role in adherence of the bacterium to porcine respiratory tract cells and mucus
Antigenic Nature used to produce antibodiesFormalin-fixed A. pleuropneumoniae serotype 1 cells (strain Shope 4074]
Carrier NameNil
Conjugation MethodNil
AntibodiesMab 11C3
Antibody type and classIgM
Assay SystemELISA, Rapid Dot ELISA and Slide agglutination test
Cross-reactivityThis antibody cross-reacted with reference strains of serotypes 1, 9 and 11
Proposed epitopesN/A
IEDB EpitopeN/A
Proposed UtilityThis Mab may provide reliable specific tools for rapid serological diagnosis of animals infected with serotypes 1, 9 and 11 by inhibition or competition ELISA. Moreover, these mAbs could be useful as a complementary specific reagents to polyclonal sera for serotyping of field isolates belonging to A. pleuropneumoniae serotypes 1, 9 and 11

Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeKlebsiella pneumoniae O1:K2   (NCBI Taxonomy)   (Drugpedia)
Basic StructureN/A
BCSDB StructureN/A
Proposed functionsIt has been shown to be an important virulence factor and potent antigen for the induction of immunoprotection
Antigenic Nature used to produce antibodiesLPS-associated proteins plus LPS
Carrier NameNil
Conjugation MethodNil
AntibodiesMab 11C3
Antibody type and classIgG2b
Assay SystemELISA
Cross-reactivityThis Mab cross-reacted with K. pneumoniae R:K18, a rough strain. This Mab did not cross-react with LPS from Klebsiella strains of the 02, 03, and 04 serotypes nor LPS from E. coli 0111:B4
Proposed epitopesThis Mab recognized the LPS core
IEDB EpitopeN/A
Proposed UtilityThis Mab showed invivo protection in mice against LPS induced homologous shock
