US Patent:

50325795, Jul 16, 1991

Filed:

Jul 25, 1990

Appl. No.:

7/558106

Inventors:

Robert M. Speights - Arvada CO
Peter J. Perna - Boulder CO
Steven L. Downing - Louisville CO

Assignee:

Coors Biotech, Inc. - Westminster CO

International Classification:

A61K 3170
A61K 3300

US Classification:

514 23

Abstract:

A method and composition for the inhibition of growth of Salmonella is provided. The effective composition of the invention is a composition which is fermented by microflora other than Salmonella at a rate competitively greater Salmonella or which is fermented by microflora other than Salmonella to produce metabolites which inhibit the growth of Salmonella. In one embodiment of the present invention, the effective composition is a class of fructo-oligosaccharides which inhibit the growth of Salmonella. More particularly, the fructo-oligosaccharidesa are sucrose molecules having from 1 to 8 fructose residues. This class of sugars is exemplified by "Neosugar" which includes 1-kestose, nystose, and 1-fructofuranosyl-nystose. The present method includes contacting Salmonella with the effective composition and can include feeding it to a domestic food anomal. The present composition includes the effective component and nutritive feed material.
