"LACTOBACILLUS CASEI SPECIES, PREPARATION OF LACTOBACILOS ACTIVATING A LIVE BODY HAVING A LACTOBACILLUS CASEI SPECIES, AND PREVENTIVE OR THERAPEUTIC AGENT AGAINST INFECTIONS IN HUMANS, ANIMALS AND PLANTS HAVING A LESTOCACILLUS" Efforts were made to develop a lactobacill which would be usable as a probiotic and to develop a lactobacill which would colonize and proliferate in infection lesions by eliminating the causal bacteria. This problem was solved by developing a species of Lactobacillus casei having the following key properties: (1) the species can be grown in the presence of any one to four amino acids as a necessary nitrogen source for growth. (2) When a growth promoting culture medium is inoculated with the species and Escherichia coli at the same count and subjected to anaerobic mixed cultivation at 37 198 C, the final lactobacillus count is 50% or more of the coliform count. . (3) When cultivated in an appropriate culture medium, the final pH value is 4.0 or below, and the highest acidity is 1.5% or higher. (4) The species is resistant to 5% bile salts. (5) The species produces an antibiotic.
