One isolate from  bima horse’s milk has the potency as a probiotic candidate. The bacterial isolate from Bima horse’s milk has the character of being resistant to acids, and bile salts, sensitive to the two antibiotics tested and can aggregate with Salmonella Thypimurium. From molecular identification, the selected Bima horse’s milk isolate has similarities with Lacticaseibacillus rhamnosus strain MG5511
