Abstract: Some lactic acid bacteria (LAB) possess probiotic properties beneficial to human health. However, both gastric acid and bile salt have adverse influences on the survival and viability of ingested probiotics. This research investigated the changes in potential probiotic properties of LAB strains after treatment with simulated gastrointestinal (GI) conditions. Three strains of LAB, namely Lactobacillus acidophilus BCRC 10695, Lactobacillusparacasei BCRC 14023, and Bifidobacterium bifidum BCRC 14615, were used...

Abstract: The health benefits of probiotics are thought to occur, at least in part, through an improved intestinal microbial balance in fish, although the molecular mechanisms whereby probiotics modulate the intestinal microbiota by means of activation of mucosal immunity are rarely explored. In this study, the effects of viable and heat-inactivated probiotic Bacillus pumilus SE5 on the intestinal dominant microbial community and mucosal immune gene expression were evaluated. The fish were fed for 60 d with 3 different...

Abstract: Mental health is closely linked to physical health. Depression (e.g., major depression) is highly prevalent worldwide and a major cause of disability. In a subgroup with treatment-resistant depression, standard pharmacotherapy interventions provide small if any incremental improvement in patient outcomes and may also require the application of an alternate approach. Therefore, in addition to the standard pharmacotherapies prescribed, patients will also be advised on the benefits of psychological counseling,...

Abstract: Lactobacillus helveticus SBT2171 (LH2171) is a lactic acid bacterium with high protease activity and used in starter cultures in the manufacture of cheese. We recently reported that consumption of cheese manufactured using LH2171 alleviated symptoms of dextran sodium sulfate (DSS)-induced colitis in mice. In this study, we have examined whether LH2171 itself exerts an inhibitory effect on the excessive proliferation of lymphocytes. We found that LH2171 inhibited the proliferation of LPS-stimulated mouse T and...

Abstract: Background: Probiotics increase beneficial microbiota and improve chronic conditions, such as atopic diseases, irritable bowel disease, and obesity. However, because there are so many probiotics, it is unknown which probiotics might have more of an effect on intestinal microbiota. Objective: To understand how two different types of probiotics influence human intestinal microbiota, human fecal microbiota were analyzed after ingestion of each of the probiotics. Methods: Ten outpatients were enrolled. Study A:...

Abstract: As studies uncover the breadth of microbes associated with human life, opportunities will emerge to manipulate and augment their functions in ways that improve health and longevity. From involvement in the complexities of reproduction and fetal/infant development, to delaying the onset of disease, and indeed countering many maladies, microbes offer hope for human well-being. Evidence is emerging to suggest that microbes may play a beneficial role in body sites traditionally viewed as being sterile. Although...

Abstract: The viability of bacteria during industrial processing is an essential quality criterion for bacterial preparations, such as probiotics and starter cultures. Therefore, producing stable microbial cultures during proliferation is of great interest. A strong correlation between the culture medium and cellular morphology was observed for the lactic acid bacterium Lactobacillus acidophilus NCFM, which is commonly used in the dairy industry as a probiotic supplement and as a starter culture. The cell shapes ranged...

Abstract: While the role of microflora is well established in the development of inflammatory bowel disease; data is still emerging regarding irritable bowel syndrome as the knowledge on brain---gut interaction grows. For both patient groups multiple efficacious treatments exist, but there are still unmet needs as long term disease control remains an issue. Given the importance of the microbiome on the development of the immune system and the interaction between the microbiome and the host organism, this 'route' is being...
