In livestock, a number of pathological conditions and/or syndromes exist which may not be attributable to infection by a single organism. In many instances, these pathological conditions and/or syndromes have an effect on the equilibrium that ordinarily exists within the various bacteria comprising the normal bacterial flora. A number of these pathological conditions and/or syndromes have been clinically referred to as dysbacteriosis and bacterial overgrowth. The present invention provides methods for evaluation of the "general health" of livestock by analyzing the composition of microbiological flora. In one aspect, a method of the invention comprises providing a sample of microbiological flora, selectively amplifying nucleic acid in the flora sample, subjecting the amplificate to restriction digestion, and then analyzing the resulting pattern of restriction fragments.
