[edit] Carbohydrate Name

O-polysaccharide

[edit] Carbohydrate Class

O-polysaccharide [LPS]

[edit] Source Microbe

Actinobacillus pleuropneumoniae serotype 4 (field isolate F6)

[edit] Basic Structure

O chains of LPS of serotypes 4 and 7 were structurally similar, being composed of repeating tetrasaccharide units with identical trisaccharide residues forming a common backbone


[edit] Proposed functions

LPS is an important virulence factor. It molecule plays an important role in adherence of the bacterium to porcine respiratory tract cells and mucus

[edit] Antigenic Nature used to produce antibodies

formalin-fixed A. pleuropneumoniae serotype 4 cells

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab 7C3

[edit] Antibody type and class

IgM

[edit] Assay System

Whole cell ELISA and slide agglutination tests

[edit] Cross-reactivity

This Mab failed to recognize surface epitopes located on other bacterial, such as H. parasuis, P. haemolytica, P. multocida capsular types A and D, Haemophilus taxon minor group, and A. suis, K. pneumoniae and B. bronchiseptica. were reactive with 26 serotype 4 isolates,11 serotype 7 isolates, and 1 each of the serotype 1 and non-typeable isolates tested

[edit] Proposed epitopes

N/A


[edit] Proposed Utility

This MAb could be useful for the serological diagnostic of animals infected with serotypes 4 and 7 by inhibition ELISA or competition ELISA. Moreover, they could be useful as complementary reagents to polyclonal sera for serotyping of field isolates belonging to A. pleuropneumoniae serotype 4 or 7
