Abstract: Provided are methods for determining susceptibility of an intestinal disorder in a companion animal. These methods include measuring a first amount of a first intestinal microorganism and/or a second amount of a second intestinal microorganism in the companion animal; comparing the first amount of the first intestinal microorganism with a first reference amount of the first intestinal microorganism, and/or comparing the second amount of the second intestinal microorganism with a second reference amount of the second intestinal microorganism; and determining that the companion animal is susceptible of an intestinal disorder, when the first amount of the intestinal microorganism is higher than the first reference amount of the first intestinal microorganism, and/or when the second amount of the second intestinal microorganism is lower than the second reference amount of the second intestinal microorganism.

Abstract: Provided are methods for determining responsiveness of a companion animal having an intestinal disorder to a diet. These methods include measuring at least a first amount of a first intestinal microorganism, comparing the first amount of the first intestinal microorganism with a first reference amount of the first intestinal microorganism, wherein the reference amount is determined based on the amounts of the intestinal microorganisms in a plurality of healthy companion animals; and determining that the companion animal is responsive to the diet, when the first amount of the intestinal microorganism is higher than the first reference amount of the first intestinal microorganism.

Abstract: The presently disclosed subject matter relates to method, compositions and food products for improving intestinal health, treating intestinal dysbiosis and/or treating an intestinal disorder in a subject, e.g., a human or a companion animal.

Abstract: The invention includes a method of treating or preventing a Staphylococcus infection in a mammal or avian species in need thereof. The methods comprise administering to the mammal or avian species a therapeutically effective amount of fosmidomycin.
