A defined probiotic or composition of anaerobic bacteria effective for controlling or inhibiting Salmonella colonization of fowl. The probiotic includes populations or cultures of 29 substantially biologically pure bacteria. In use, the probiotic is administered to the subject fowl in an amount effective for increasing resistance to Salmonella colonization thereof. The invention also relates to a novel method for isolating probiotics which are effective for controlling or inhibiting Salmonella colonization of domestic animals, from fecal droppings, cecal contents or large intestines of the adult animals. The droppings, cecal contents or large intestine are combined with a culture medium and incubated without dilution (i.e. batch culture) under anaerobic conditions. Following this preliminary incubation, the resultant culture is subjected to continuous flow conditions until a steady state is achieved, after which time the steady state culture may be recovered for use as a probiotic.
