## Abstract

The present invention relates to the use of a non-digestible carbohydrate in the manufacture of a composition for treating or preventing pathogenic bacteria in the large intestine of a pet animal. It also provides a method for the prevention or treatment of a pathogenic bacteria in the large intestine of a pet animal, the method comprising administering to said pet animal a composition which comprises a non-digestible carbohydrate.

## Claims

### Claim 1

A method for treating a pathogenic Campylobacter, Escherichia coli or Salmonella bacteria in a large intestine of a dog or cat, the method comprising the step of administering to the dog or cat a pet food product comprising of a non-digestible carbohydrate which is,
a) a dietary fiber source selected from the group consisting of coconut endosperm fiber, beet pulp, citrus pulp, rice bran, carob bean or gum talha and combinations thereof, and/or
b) an oligosaccharide selected from the group consisting of galactooligosaccharide, maltooligosaccharide, xylooligosaccharide, raffinose and combinations thereof,
wherein the pet food product is administered to deliver the non-digestible carbohydrate of a) and/or b), in an amount sufficient to treat the pathogenic Campylobacter, Escherichia coli or Salmonella bacteria in the large intestine of the dog or cat.

### Claim 2 (depends on 1)

The method of claim 1, wherein the pathogenic bacteria is Campylobacter jejuni or Salmonella enterica.

### Claim 3

The method of 1, wherein the pathogenic bacteria is Campylobacter jejuni and the non-digestible carbohydrate comprises a galactooligosaccharide.

### Claim 4 (depends on 1)

The method of claim 1, wherein the pathogenic bacteria is Salmonella enterica Serotype Typhimurium and the non-digestible carbohydrate comprises a galactooligosaccharide.

### Claim 5 (depends on 3, 4)

The method of claim 3 or 4 wherein the pet food is administered in an amount sufficient to cause a decrease in intestinal pH thereby treating the pathogenic bacteria.

### Claim 6 (depends on 1)

The method of claim 1, wherein the pathogenic bacteria is Campylobacter jejuni and the non-digestible carbohydrate comprises a coconut endosperm fiber.
