Abstract: A liquid adherent disinfectant composition for topical application comprises an aqueous acidic suspension of previously coagulated casein containing an aliphatic sulfate detergent as the effective agent for solubilizing the casein and converting it to a mucilaginous condition. The preparation also preferably contains glycerin and Lactobacillus-elaborated antibiotic-like factors. The composition can be prepared by fermenting a nonfat dry milk culture medium with harmless lactic acid-producing bacteria, such as Lactobacillus acidophilus, until the casein coagulates, thereafter mechanically dispersing the coagulated casein and solubilizing it with the aliphatic sulfate detergent. The resulting disinfectant composition can be used as a teat dip for preventing mastitis in cattle, or for other topical disinfecting purposes with domestic animals. The compositions adhere to the areas to which they are applied while being readily removable by water washing.

Abstract: Stabilized liquid suspensions of probiotic Lactobacilli are provided as a dispersion of the viable cells in sunflower seed oil for administration to animals. The viable cells prior to combining with the oil have been dried at a favorable pH and in the presence of stabilizing additives. The dried cells are further characterized by having a low water activity. The invention has particular utility in administering Lactobacillus acidophilus cells as a drench to domestic animals.
