Phylum	Proteobacteria
Class	Gamma Proteobacteria
Order	Pasteurellales
Family	Pasteurellaceae
Genus	Pasteurella
Species	P. haemolytica
Binomial	Pasteurella haemolytica

[edit] Surface Characteristics

The cell surface lipopolysaccharide (LPS) of Pasteurella haemolytica serotype 1 is composed of three regions consisting of lipid A, core oligosaccharides, and O-antigen polysaccharides. The O-antigen part consists of the following residues : -3)-β-D-Galp-(1-->3)-β-D-GalpNAc-(1-->4)-β-D-Galp-(1-. The core oligosaccharide part consists of the following residues : β-D-Galp-(1-->7)-D-gro-α-D-manHepp-(1-->6)-D-gro-α-D-manHepp-(1-->6)-β-D-Glcp-(1-->4)-L-gro [branched to L-gro-α-D-manHepp-(1-->2)-L-gro-α-D-manHepp-(1-->3)] and [branched to α-D-Glcp-(1-->6)] -α-D-manHepp-(1--/lipid A

[edit] Pathogenic Activity

It causes mastitis in sheep and shipping fever (see pasteurellosis, pneumonic) in cattle.
