Sumario:BACKGROUND: Bekasam is one of the traditional foods in South Sumatra, Indonesia, a mixture of fermented fish containing Lactic Acid Bacteria (LAB), Lactobacillus sp. Non-commensal bacteria and probiotics can induce intestinal mucosal immune responses. AIM: This pilot study aimed to see the efficacy of Lactobacillus sp. to the immune response of the intestinal mucosa by assessing the levels of IgA in the intestinal fluid and markers of T cell populations, such as CD4 and CD8 in the intestinal mucosa. METHODS: This study was an in vivo experimental study. As many as 30 rats were grouped into 3 treatment groups (doses 107, 108, and 109 CFU/rat/day, for 7 days) and 2 groups of controls (negative control, 10% non-fat milk, and positive control, Lactobacillus casei 108 CFU/rat/day for 7 days). At the end of the treatment, the intestinal mucosa was taken to examine the levels of IgA, CD4 and CD8 using the Enzyme-Linked Immunosorbent Assay (ELISA) method, according to the manuals of each ELISA kit. All displays of research data were presented with means ± SD. T-test was used to assess the significance of differences. RESULTS: Secretion of Ig A increased with the addition of Lactobacillus sp. from bekasam. Administration of Lactobacillus sp. yielded no effect on helper T cell level (CD4 markers), as well as on cytotoxic T cell levels (CD8 markers). CONCLUSION: Lactobacillus sp. probiotic from bekasam improved the intestinal mucosal immune system by increasing the production of Ig A, but exhibited no effect on T lymphocyte cells.
