Egg productivity is declined by stress. It has been reported that some food supplements can improve the egg productivity due to a reduction of environmental stress. We evaluated the effect of fermented waste mushroom bed (FWMB) as a dietary additive on egg productivity. Hens were fed control food (control group, n = 100) or 3% FWMB-added food (FWMB group, n = 100) for 16 months. The number of eggs, soft-shelled eggs, and broken eggs were recorded for 15 months. We also evaluated stress-related markers (ovotransferrin, lipid peroxide, and the heterophil-to-lymphocyte ratio)...

Intestinal regulatory T (Treg) cells are critical to maintaining immune tolerance to dietary antigens and gut microbiota. This paper reviews several papers on this topic that were recently published by Japanese researchers. Specifically, Prof. K. Honda and his group have found that commensal microbiota capable of metabolizing butyrate induces the differentiation of colonic Treg cells. In a separate work, Prof. Y. Yokoyama and his group used a novel, culture-independent analytical method (the Yakult Intestinal Flora-Scan) for detection of bacteria in the bloodstream...

Context • Crohn's disease and ulcerative colitis result in similar gastrointestinal (GI) symptoms, including pain, diarrhea, stools with mucus or blood, and ulceration or tissue damage within the alimentary canal. Gut microbiota play a crucial role in triggering, maintaining, and exacerbating inflammatory bowel disease (IBD). Probiotics might help to rebalance the gut flora in a positive way, shifting from pro- to anti-inflammatory. Objectives • The study intended to investigate the safety and use of probiotics and the biological effects of probiotic bacteria on IBD...

Myocardial infarction (MI) is the main cause of cardiovascular crises that entails serious concerns in mortality, morbidity, and cost to the society. The main therapeutic goal of modern cardiology is to develop novel approaches to minimize inflammation, myocardial necrosis/apoptosis, and enhance cardiac repair after MI. Though MI can be affected by genetic and environmental factors, the search for targeting lifestyle factors has been of greater interest. One such potential factor is the microbiota, the human intestinal microbial community...

Fecal microbiota transplantation (FMT), also known as fecal bacteriotherapy or fecal infusion, consists of injection of a liquid filtrate of feces from a healthy donor into the gastrointestinal tract of a recipient individual. FMT has been proposed as a therapeutic approach for functional diseases of the gastrointestinal tract by reestablishment of a wide diversity of intestinal flora. Clostridium difficile infection (CDI) treatment guideline from American Gastroenterology Association (AGA) recommends that FMT can be used as the treatment protocols of relapse CDI...

Understanding gut microflora alterations associated with gut parasites and other pathogens that drive these alterations may help to promote the understanding of intestinal flora's role in multiple-infected individuals. This study examined the effects of dual infection with Eimeria tenella and subgroup J avian leukosis virus (ALV-J) on the chick cecal microbiome. Specific-pathogen-free (SPF) chicks were infected with either ALV-J strain NX0101 at 1 day of age or E. tenella at 14 days of age, another group was infected with both pathogens...

The gut microflora dysbiosis has been closely related with the inflammatory bowel disease (IBD). In this study, the effect of polysaccharides from Chrysanthemum morifolium Ramat on the gut microbiota was evaluated by ulcerative colitis (UC) rat model. Physiological and pathological analyses suggested that Chrysanthemum polysaccharides possessed notably protective effects on UC in vivo. Based on the Illumina MiSeq platform, 16S rRNA sequencing of the rat colonic contents indicated that the intestinal flora structure remarkably changed in the model rats and the tendency was alleviated to a certain degree by treatment with different dosages of Chrysanthemum polysaccharides...

Inflammatory bowel disease (IBD) is associated with decreased bone mass and alterations in bone geometry from the time of diagnosis, before anti-inflammatory therapy is instituted. Deficits in bone mass can persist despite absence of symptoms of active IBD. The effects of IBD on the skeleton are complex. Protein-calorie malnutrition, inactivity, hypogonadism, deficits in calcium intake and vitamin D consumption and synthesis, stunted growth in children, decreased skeletal muscle mass, and inflammation all likely play a role...

Phlebotomine sand flies are hematophagous insects that harbor bacterial, viral and parasitic agents like Bartonella sp., Phleboviruses and Leishmania spp., respectively. There are few reports on bacterial microbiota of Phlebotomus (P.) papatasi but no data available for natural populations of Turkey, where leishmaniasis is endemic. Therefore, we aimed to investigate the midgut bacterial flora of different populations of P. papatasi. Sand flies were collected from different towns (Karaburun, Urla, Ayvacik and Başçayır) located in the western part of Turkey...

Recovery of the T lymphocyte compartment within a lymphopenic host by lymphopenia-induced proliferation (LIP) is regulated by inter- and intraclonal competition for limited resources, including homeostatic cytokines and peptide:MHC (pMHC) complexes with which the TCR can interact at least weakly to yield a tonic signal. Importantly, the process of LIP can synergize with other factors that promote T cell activation to drive inflammatory disease. While reconstitution of the lymphoid compartment of immune deficient Rag(-/-) mice by transfer of wild-type hematopoietic stem cells (HSC) does not generally result in an overt disease phenotype, transfer of HSC deficient in expression of the co-inhibitory molecule PD-1 results in severe systemic autoimmunity driven by newly generated T cells that emerge from the thymus into the periphery and undergo LIP...

This paper argues that multiple sclerosis (MS) is the result of an autoimmune attack against components of the central nervous system (CNS). The effector cells involved in the pathogenic process are CNS-autoreactive T cells present in the healthy immune system in a resting state. Upon activation, these cells cross the blood-brain barrier and attack the CNS target tissue. Recent evidence indicates that autoimmune activation may happen in the intestine, following an interaction of bacterial components of the gut flora with local CNS autoreactive T cells...

Vaginal seeding refers to the practice of inoculating a cotton gauze or a cotton swab with vaginal fluids to transfer the vaginal flora to the mouth, nose, or skin of a newborn infant. The intended purpose of vaginal seeding is to transfer maternal vaginal bacteria to the newborn. As the increase in the frequency of asthma, atopic disease, and immune disorders mirrors the increase in the rate of cesarean delivery, the theory of vaginal seeding is to allow for proper colonization of the fetal gut and, therefore, reduce the subsequent risk of asthma, atopic disease, and immune disorders...

Urinary tract infections (UTIs) currently rank amongst the most prevalent bacterial infections, representing a major health hazard. UTIs in females usually start as vaginal infections and ascend to the urethra and bladder. Recurrent UTIs (rUTIs) can be defined as at least three episodes of UTI in 1 year or two episodes in 6 months. Various antibiotics have been the mainstay of therapy in ameliorating the incidence of UTIs, but recurrent infections continue to afflict many women. It necessitates the exploitation of alternative antimicrobial therapy...

A bidirectional route of communication between the gastrointestinal tract and the central nervous system, termed the "gut-brain axis", is becoming increasingly relevant to treatment of cerebral damage. Panax Notoginsenoside extract (PNE) is extremely popular for prevention and treatment of cardio-cerebrovascular ischemic diseases although their plasma and cerebral exposure levels were extremely low. To date, the mechanisms underlying the neuroprotective effects of PNE remain largely unknown. In the present study, the neuroprotective effects of PNE are systematically studied via investigating the regulation of PNE on gastrointestinal microbial community and gamma aminobutyric acid (GABA) receptors...

Chronic kidney disease results in disruption of the intestinal epithelial barrier as well as profound changes in the gut microbial flora. These events are largely mediated by (1) heavy influx of circulating urea to the gut lumen and (2) dietary restrictions of foods containing high fiber (such as fruits and vegetable) and symbiotic organisms (such as yogurt and cheese) imposed to mitigate hyperkalemia and hyperphosphatemia. Collectively, these factors promote systemic inflammation and cardiovascular morbidity by mediating microbial dysbiosis, disruption of the intestinal epithelial barrier, and translocation of endotoxin, bacterial fragments, and uremic toxins across the "leaky gut" into the bloodstream...

Jean-François Bach
The incidence of autoimmune diseases has been steadily rising. Concomitantly, the incidence of most infectious diseases has declined. This observation gave rise to the hygiene hypothesis, which postulates that a reduction in the frequency of infections contributes directly to the increase in the frequency of autoimmune and allergic diseases. This hypothesis is supported by robust epidemiological data, but the underlying mechanisms are unclear. Pathogens are known to be important, as autoimmune disease is prevented in various experimental models by infection with different bacteria, viruses and parasites...
