Incubation of Pasteurella haemolytica and Pasteurella multocida lipopolysaccharide with sheep lung surfactant. 1986

K A Brogden, and R B Rimler, and R C Cutlip, and H D Lehmkuhl

Lipopolysaccharides (LPS) were extracted from a serotype of each of 2 species of Pasteurella isolated from sheep with respiratory tract infections. Lipopolysaccharides from P haemolytica 82-25 (serotype 1A) or P multocida P-1573 (serotype 12) were mixed with sheep lung surfactant and were incubated for 6 hours at 37 C. After incubation, LPS-surfactant mixtures were centrifuged overnight in sucrose density gradients, and fractions were analyzed. Binding occurred between LPS and surfactant vesicles resulting in a stable complex with densities greater than those with the surfactant alone. The surfactant alone had a density of 1.052 to 1.060 g/ml. Diffuse bands of surfactant had a density of 1.075 to 1.092 when incubated with P haemolytica LPS and a density of 1.069 to 1.105 when incubated with P multocida LPS.

D007507	Therapeutic Irrigation	The washing of a body cavity or surface by flowing water or solution for therapy or diagnosis.	Douching,Lavage,Douchings,Irrigation, Therapeutic,Irrigations, Therapeutic,Lavages,Therapeutic Irrigations
D008070	Lipopolysaccharides	Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)	Lipopolysaccharide,Lipoglycans
D010325	Pasteurella	The oldest recognized genus of the family PASTEURELLACEAE. It consists of several species. Its organisms occur most frequently as coccobacillus or rod-shaped and are gram-negative, nonmotile, facultative anaerobes. Species of this genus are found in both animals and humans.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
