Rheumatoid arthritis (RA) is an autoimmune disease with progressive joint disorder. The complex interplay of genetic and environmental influences is important for the development of the disease. A growing body of evidence has shed light on the association of dysbiosis of gut microbiota with RA. Certain gut microbial strains have been shown to inhibit or attenuate immune responses in RA experimental models, suggesting that specific species among intestinal commensal bacteria may play either a pathogenic or a protective role in the development of RA...

There is growing interest in the use of probiotic lactic acid bacteria (LAB) for prevention of hypercholesterolaemia. This study assessed the cholesterol lowering ability of Pediococcus acidilactici LAB4 and Lactobacillus plantarum LAB12 in growth media. Both LAB yielded >98% (39.2 μg/ml) cholesterol lowering in growth media. Nile Red staining indicated direct assimilation of cholesterol by the LAB. The LAB were then explored for their prophylactic (pre-treatment of HT29 cells with LAB prior to cholesterol exposure) and biotherapeutic (treatment of HT29 cells with LAB after exposure to cholesterol) use against short and prolonged exposure of HT29 cells to cholesterol, respectively...

Hypertension is a major risk factor for cardiovascular diseases. Optimizing blood pressure results in an overall health outcome. Over the years, the gut microbiota has been found to play a significant role in host metabolic processes, immunity, and physiology. Dietary strategies have therefore become a target for restoring disturbed gut microbiota to treat metabolic diseases. Probiotics and their fermented products have been shown in many studies to lower blood pressure by suppressing nitrogen oxide production in microphages, reducing reactive oxygen species, and enhancing dietary calcium absorption...

PURPOSE OF REVIEW: To summarize evidence on the efficacy of nonantibiotic treatments in the prevention of recurrent urinary tract infections (UTIs). The need for antibiotic-free regimens seems to be imperative given the worldwide rates of resistance of uropathogens to available antibiotics. RECENT FINDINGS: In the recently published literature, cranberry products and probiotics are the focus of research. They both seem to be effective in preventing recurrent UTIs compared with placebo, but their benefit becomes less clear when they are compared with antibiotics...

Albert J Czaja
The intestinal microbiome is a reservoir of microbial antigens and activated immune cells. The aims of this review were to describe the role of the intestinal microbiome in generating innate and adaptive immune responses, indicate how these responses contribute to the development of systemic immune-mediated diseases, and encourage investigations that improve the understanding and management of autoimmune hepatitis. Alterations in the composition of the intestinal microflora (dysbiosis) can disrupt intestinal and systemic immune tolerances for commensal bacteria...

Ken Graham, Rosemary Rea, Paul Simpson, Helena Stack
Enterococci show higher proteolytic activities than other lactic acid bacteria and thus have received considerable attention in scientific literature in recent years. Proteolytic enzymes of enterococci have warranted the use of some species as starter, adjuncts or protective cultures and as probiotics, while in some strains they have also been linked with virulence. Consequently, the isolation and identification of proteolytic enterococci is becoming of increasing interest and importance. However, current screening methods for proteolytic enterococci can be time consuming, requiring a two-step procedure which may take up to 96h...

Axillary malodour is a frustrating condition for many people. It can lead to significant discomforts and various psychological effects. The underarm microbiome generally plays a major role in axillary malodour formation. Not only the bacteria on the armpit epidermis, but especially those living in the sweat glands, sweat pores and hair follicles play a pivotal role in malodour development. In order to treat underarm malodour, this viewpoint paper envisions a bacterial treatment. Replacing the autochthonous malodour causing microbiome with a non-odour causing microbiome, through an armpit bacterial transplantation or direct application of probiotics/non-odour causing bacteria could resolve the condition...
