Lactobacillus rhamnosus Probiotics for Diarrhea Prevention
Acute diarrheal disease affects over 1.7 billion people annually, with particularly severe consequences for children under five, who experience approximately 525,000 deaths per year. Clinical studies demonstrate that Lactobacillus rhamnosus GG can reduce the duration of acute infectious diarrhea by 24-30 hours, with dose-dependent colonization achieving concentrations of 106-108 CFU/g in fecal samples. The mechanism involves multiple pathways: competitive exclusion of pathogens, secretion of bacteriocins, enhancement of epithelial barrier function, and modulation of host immune responses.
The challenge lies in developing probiotic formulations that maintain viability through gastric transit while demonstrating strain-specific efficacy against diverse enteric pathogens.
This page brings together solutions from recent research—including multi-strain synbiotic formulations, bacteria-derived antimicrobial peptides, specific bacterial isolates with pathogen adhesion inhibition properties, and microbial consortia with genomically-characterized strains. These and other approaches provide clinical practitioners with evidence-based interventions for both prevention and treatment of acute and antibiotic-associated diarrhea.

Archana Patil - International Journal for Research in Applied Science and Engineering Technology (IJRASET), 2024
Abstract: This study explores the potential of using probiotic lactic acid bacteria (LAB) that produce bacteriocins as a novel approach to controlling gut microbiota dysbiosis. Gut dysbiosis, characterized by an imbalance in the composition of the gut microbiota, is implicated in various health disorders. Probiotic LAB have gained attention for their ability to promote a balanced gut microbiota. Bacteriocin-producing LAB offer an added advantage by inhibiting pathogenic bacteria and promoting the growth of beneficial microbes. This review summarizes the current knowledge on the mechanisms of probiotic LAB and their bacteriocins in modulating gut microbiota composition. Additionally, key clinical studies and potential applications of bacteriocin-producing LAB in mitigating gut dysbiosis are discussed.

Zhiwei Yan, Zhuangzhuang Liu, Yong Ma - MDPI AG, 2023
Antibiotic-associated diarrhea (AAD) refers to diarrhea caused by gut microbiota disorders after the use of antibiotics, which seriously threatens the health of humans and animals. Therefore, it is necessary to find an effective therapy to treat AAD. This research aimed to explore the effects of Lactobacillus plantarum H-6 (L. plantarum H-6) and Weissella viridescens J-1 (W. viridescens J-1) on alleviating antibiotic-associated diarrhea induced by lincomycin hydrochloride (LH) in mice. The results show that L. plantarum H-6 could significantly reduce the expression of pro-inflammatory factors such as IL-1 and IL-6 in colon tissue. At the same time, L. plantarum H-6 significantly increased the abundance of Lactobacillus and Akkermansia, decreased the abundance of Bacteroides, and increased the contents of L-tryptophan, LysoPC (20:4 (8Z, 11Z, 14Z, 17Z)), reduced riboflavin, threoninylmethionine, and N-palmitoyl in serum. However, W. viridescens J-1 had little effect on the treatment of AAD. It can be concluded that L. plantarum H-6 can regulate mices colonic microbial composition, i... Read More
