Lactobacillus Rhamnosus for Enhanced Gut Brain Axis

Combination live biotherapeutic treatments for restoring microbiome balance to treat diseases like infant diarrhea and vaginal infections. The treatments involve administering a specific blend of bacteria strains, Bifidobacterium and Vertebrate-Associated Lactobacillaceae, that inhibit pathogen growth and immune responses. The bacteria strains are chosen to have synergistic effects when cultured together. This combination therapy aims to improve efficacy and reduce dosage compared to single strain probiotics.

The genus Lactobacillus is a heterogeneous group of lactic acid bacteria (LAB) with important implications in biotechnology. It is a predominant microorganism in the world of gastrointestinal health, but various other uses are being explored. They have long been considered in the generally recognized as safe (GRAS) category by the Food and Drug Authority (FDA). They have been extensively used in fermentation and there is growing interest regarding their use in gut health, vaccine production, and biomedical innovation. This chapter highlights the application of lactobacilli in healthcare.

Abstract Antibiotic associated diarrhea frequently complicates treatment of infections. A recent randomized, double-blind, placebo-controlled trial tested a proprietary probiotic mixture and found it reduced the incidence of AAD by 16%. This is encouraging for patients, but future progress on probiotics for AAD and other conditions depends on transparency around strain selection, probiotic design guided by preclinical mechanistic studies, and rigorously conducted human studies.

Conventional dairy probiotics products that include yogurts/curds and cheese are considered the chief source of probiotic microbiome. Several health benefits have been attributed to the ingestion of probiotic microbiome. They were supposed to improve immunity and increase resistance to infection and improve general well-being. They aid in the digestion of lactose, which results in the reduction in intestinal bloating, flatulence, and discomfort. It has also been suggested that they offer protection against Clostridium botulinum spores and associated toxins (a feasible reason for abrupt sudden infant death syndrome or infant death syndrome). To prevent and treat diarrheal disorder, the most acknowledged therapeutic submission is probiotics administration. The diarrhea disorders include rota virus-induced diarrhea in toddlers and old-age people. They prevent infection and traveler's diarrhea and protect against some kinds of cancer. Decrease in blood cholesterol levels and reduction in incidence of cardiovascular disease have also been attributed to probiotics. Probiotics specifically ... Read More

Diarrhea is an atypical state of the digestive system characterized by a soft or watery texture in bowel movements. Antibiotic-related diarrhea is common in the elderly due to extensive antibiotic use. Probiotics are vital microorganisms that support the intestinal flora and reduce bacterial colonization in the intestinal wall. This study aimed to assess the effectiveness, type, and dose of probiotics for diarrhea in the elderly.

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.

Background: Antibiotic-associated diarrhea is a condition reported in 535% of patients treated with antibiotics, especially in older patients with comorbidities. In most cases, antibiotic-associated diarrhea is not associated with serious complications, but it can prolong hospitalization and provoke Clostridium difficile infection. An important role in the prevention of antibiotic-associated diarrhea is carried out by some probiotic strains such as Lactobacillus GG or the yeast Saccharomyces boulardii that showed good efficacy and a significant reduction in antibiotic-associated diarrhea. Similarly, the Limosilactobacillus reuteri DSM 17938 showed significant benefits in acute diarrhea, reducing its duration and abdominal pain.

As different probiotic supplements become increasingly seen in the market, questions regarding their use for gut health from patients rises as well. Because these supplements do not require FDA approval, their safety and efficacy is often unknown and limited research available poses an even greater challenge for healthcare providers when prompted with questions regarding their use. This article summarizes evidence-based recommendations provided by the American Gastroenterological Association (AGA) and the World Gastroenterology Organization (WGO). Of the conditions discussed, supportive evidence on the use of probiotics is mostly seen in the prevention of C. diff associated diarrhea, prevention of antibiotic associated diarrhea and treatment of IBS. Of the millions of different strains available, the recurring genus seen across multiple disease states is Lactobacillus.

Infant feces and breast milk are sources of lactic acid bacteria with interesting functional and technological properties. Therefore, we focused on the isolation and characterization of new potential probiotic strains from infant feces and breast milk. Nine strains were identified based on 16S rRNA sequences of Lacticaseibacillus rhamnosus, Limosilactobacillus reuteri, and Lactobacillus gasseri.

Context: Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. One of the most common indications for probiotic treatment is the prevention of antibiotic-associated diarrhea (AAD). Unfortunately, many probiotic products used for AAD are not supported by rigorous independent research, and often results in non-evidence-based usage. Additionally, it is not clear when is the most appropriate time to take a probiotic when on an antibiotic course.

The method involves heating the liquid source, then filtering it to separate out the sialyloligosaccharides. The filtrate is further processed by nanofiltration and enzyme reactions to concentrate the sialyloligosaccharides. The resulting extract is a sialyloligosaccharide-enriched composition that can be used as a nutritional supplement for infants and adults.
