Previously, we used an immune-based screening strategy to select two potential probiotic strains from infant feces in China, Bifidobacterium breve 207-1 (207-1) and Lacticaseibacillus paracasei 207-27 (207-27). In this study, the in vitro immunological effects and potential in vivo general health benefits of these two strains were evaluated using Lacticaseibacillus rhamnosus GG (LGG) as the control. The results showed that 207-1 and 207-27 significantly and differentially modulated the cytokine profiles of primary splenic cells, while did not induce abnormal systemic immune responses in healthy mice. They also modulated the gut microbiota composition in a strain-dependent manner, thus decreasing Gram-negative bacteria and increasing health-promoting taxa and short-chain fatty acid levels, particularly butyric acid. Conclusively, 207-1 and 207-27 shaped a robust gut environment in healthy mice in a strain-specific manner. Their potential immunomodulatory effects and other elite properties will be further explored using animal models of disease and subsequent clinical trials. This immune-based screening strategy is promising in efficiently and economically identifying elite candidate probiotics.<\/jats:p>","DOI":"10.3390\/nu14173651","type":"journal-article","created":{"date-parts":[[2022,9,7]],"date-time":"2022-09-07T01:51:57Z","timestamp":1662515517000},"page":"3651","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Potential Health-Promoting Effects of Two Candidate Probiotics Isolated from Infant Feces Using an Immune-Based Screening Strategy"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0704-9486","authenticated-orcid":false,"given":"Huijing","family":"Liang","sequence":"first","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolei","family":"Ze","sequence":"additional","affiliation":[{"name":"BYHEALTH Institute of Nutrition & Health, Guangzhou 510663, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silu","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yimei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenrui","family":"Peng","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9333-818X","authenticated-orcid":false,"given":"Ruyue","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengling","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"},{"name":"Department of Infectious Disease Prevention, Sichuan Tianfu New Area Public Health Center, Chengdu 610213, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simou","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruikun","family":"He","sequence":"additional","affiliation":[{"name":"BYHEALTH Institute of Nutrition & Health, Guangzhou 510663, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7464-5272","authenticated-orcid":false,"given":"Fang","family":"He","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuguang","family":"Zhang","sequence":"additional","affiliation":[{"name":"BYHEALTH Institute of Nutrition & Health, Guangzhou 510663, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Hygiene, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"506","DOI":"10.1038\/nrgastro.2014.66","article-title":"Expert consensus document.
