摘要
The use of probiotics for human and animal health is continuously increasing. The probiotics used in humans commonly come from dairy foods, whereas the sources of probiotics used in animals are often the animals' own digestive tracts. Increasingly, probiotics from sources other than milk products are being selected for use in people who are lactose intolerant. These sources are non-dairy fermented foods and beverages, non-dairy and non-fermented foods such as fresh fruits and vegetables, feces of breast-fed infants and human breast milk. The probiotics that are used in both humans and animals are selected in stages; after the initial isolation of the appropriate culture medium, the probiotics must meet important qualifications, including being non-pathogenic acid and bile-tolerant strains that possess the ability to act against pathogens in the gastrointestinal tract and the safety-enhancing property of not being able to transfer any antibiotic resistance genes to other bacteria. The final stages of selection involve the accurate identification of the probiotic species.

益生菌在人类和动物健康中的使用不断增加。人类使用的益生菌通常来自乳制品，而动物中使用的益生菌来源通常是动物自身的消化道。越来越多地选择来自乳制品以外来源的益生菌用于乳糖不耐症的人群。这些来源是非乳制品发酵食品和饮料，非乳制品和非发酵食品，如新鲜水果和蔬菜，母乳喂养婴儿粪便和人类母乳。用于人类和动物的益生菌分阶段选择;在最初分离出适当的培养基后，益生菌必须符合重要的资格，包括具有抵抗胃肠道病原体作用的非病原性酸和耐胆汁菌株，以及不能提高安全性的特性。将任何抗生素抗性基因转移到其他细菌。选择的最后阶段涉及准确鉴定益生菌物种。
