ZusammenfassungEine Dysbiose bezeichnet im Gegensatz zur Eubiose, Normobiose oder Symbiose Veränderungen der intestinalen Mikrobiota (früher als Darmflora bezeichnet), die mit krankhaften, häufig entzündlichen Symptomen korreliert ist. Ursachen einer Dysbiose sind z. B. eine Überwucherung mit pathogenen Keimen, chronisch entzündliche Darmerkrankungen, aber auch Einflüsse durch Arzneimittel wie Antibiotika, Kortikosteroide etc. Vielfältige weitere Wechselwirkungen sind zu berücksichtigen wie Ernährungseinflüsse, Genussgifte (Rauchen, Alkohol) sowie auch Wechselwirkungen mit dem Hormonsystem, de

Abstract:

Microbial symbioses significantly contribute to diverse organisms, where long-lasting associations tend to result in symbiont genome erosion, uncultivability, extinction, and replacement. How such inherently deteriorating symbiosis can be harnessed to stable partnership is of general evolutionary interest. Here, we report the discovery of a host protein essential for sustaining symbiosis. Plataspid stinkbugs obligatorily host an uncultivable and genome-reduced gut symbiont, Ishikawaella. Upon oviposition, females deposit “capsules” for symbiont delivery to offspring. Within the capsules, the f

Abstract:

Symbiosis has significantly contributed to organismal adaptation and diversification. For establishment and maintenance of such host–symbiont associations, host organisms must have evolved mechanisms for selective incorporation, accommodation, and maintenance of their specific microbial partners. Here we report the discovery of a previously unrecognized type of animal organ for symbiont sorting. In the bean bug Riptortus pedestris, the posterior midgut is morphologically differentiated for harboring specific symbiotic bacteria of a beneficial nature. The sorting organ lies in the middle of the

Abstract:

Intestinal epithelial cells (IECs) are continuously exposed to large numbers of commensal bacteria but are relatively insensitive to them, thereby averting an excessive inflammatory reaction. We have previously reported that the hyporesponsiveness of a human IEC line to LPS was primarily the result of a down-regulation of TLR4 gene transcription through epigenetic mechanisms. In the present study we show that DNA methylation in the 5′ region of the TLR4 gene is significantly higher in IECs than in splenic cells in vivo. The methylation was shown to be dependent on the differentiation state of

How and when symbionts are acquired by their animal hosts has a profound impact on the ecology and evolution of the symbiosis. Understanding symbiont acquisition is particularly challenging in deep-sea organisms because early life stages are so rarely found. Here, we collected early developmental stages of three deep-sea bathymodioline species from different habitats to identify when these acquire their symbionts and how their body plan adapts to a symbiotic lifestyle. These mussels gain their nutrition from chemosynthetic bacteria, allowing them to thrive at deep-sea vents and seeps worldwide

Abstract:

Micronutrients influence hormone action and host metabolism. Dietary minerals, trace elements, and vitamins can alter blood glucose and cellular glucose metabolism, and several micronutrients are associated with the risk and progression of type 2 diabetes. Dietary components, microbes, and host immune, endocrine, and metabolic responses all interact in the intestine. There has been a focus on macronutrients modifying the host-microbe relationship in metabolic disease. Micronutrients are positioned to alter host-microbe symbiosis that participates in host endocrine control of glucose metabolism

Abstract:

Accumulating clinical evidence supports co-morbidity of irritable bowel, irritable eye and irritable mind symptoms. Furthermore, perturbation of the microbiota–host symbiosis (dysbiosis) is considered a common pathogenic mechanism connecting gastrointestinal, ocular and neuropsychiatric symptoms. Consequently, maintaining or restoring microbiota–host symbiosis represents a new approach to treat these symptoms or to prevent their relapses. Current treatment approach assigned a primary role to live probiotics alone or in combination with prebiotics to enhance colonization of beneficial bacteria

The purpose of research is to study the effect of a biologically active composition of microbial origin (BACMO) “Symbion-D” on the microbial composition of the intestine and the immunity of calves with dyspepsia. The studies were carried out on calves of the Holstein breed of the neonatal period, belonging to the Federal State Unitary Enterprise Omskoye. The criteria for inclusion in the experimental group of animals was the clinical sign "diarrhea". The calves of the experimental group were fed BACMO “Symbion-D” daily for 5–7 days individually, depending on the weight of the calf and the seve

Abstract:

The intestinal microbiota consists of trillions of bacteria, viruses, and fungi that achieve a perfect symbiosis with the host. They perform immunological, metabolic, and endocrine functions in the body. The microbiota is formed intrauterine. Dysbiosis is a microbiome disorder characterized by an imbalance in the composition of the microbiota, as well as changes in their functional and metabolic activities. The causes of dysbiosis include improper nutrition in pregnant women, hormone therapy, the use of drugs, especially antibiotics, and a lack of exposure to the mother’s vaginal microbiota du

Naringin is a kind of multi-source food additive which has been explored broadly for its various biological activities and therapeutic potential. In the present study, the protective effect and mechanism of naringin on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice were investigated. The results showed that naringin significantly alleviated DSS-induced colitis symptoms, including disease activity index (DAI), colon length shortening, and colon pathological damage. The tissue and serum secretion of inflammatory cytokines, as well as the oxidative stress, were decreased acc

Abstract:

AbstractGut symbionts can augment resistance to pathogens by stimulating host-immune responses, competing for space and nutrients, or producing antimicrobial metabolites. Gut microbiota of social bees, which pollinate many crops and wildflowers, protect hosts against diverse infections and might counteract pathogen-related bee declines. Bumble bee gut microbiota, and specifically abundance ofLactobacillus‘Firm-5’ bacteria, can enhance resistance to the trypanosomatid parasiteCrithidia bombi. However, the mechanism underlying this effect remains unknown. We hypothesized that the Firm-5 bacteriu

Abstract Intestinal mucus forms the first line of defense against bacterial invasion while providing nutrition to support microbial symbiosis. How the host controls mucus barrier integrity and commensalism is unclear. We show that terminal sialylation of glycans on intestinal mucus by ST6GALNAC1 (ST6), the dominant sialyltransferase specifically expressed in goblet cells and induced by microbial pathogen-associated molecular patterns, is essential for mucus integrity and protecting against excessive bacterial proteolytic degradation.

Abstract:

The intestinal community, including the commensal microbial flora as well as the host tissues, represents a functional whole in vivo. Under physiological circumstances, this symbiosis brings great benefit for the host; however, critical illness induces profound disturbances in the intestinal ecosystem affecting both procaryotic and eucaryotic members. Today, 25 years after the gut was first described as a motor of multiple organ dysfunction syndrome, the role of the injured splanchnic compartment in the pathomechanism and development of critical illness is still in the first line of research.

This study employed multilocus sequence analysis and an analysis of host-specific physiological and genetic traits to assign five sourdough isolates to rodent- or human-specific lineages. Comparative genome hybridization revealed that the model sourdough isolate LTH2584 had a genome content very similar to that of the model rodent isolate 100-23. These results demonstrate that sourdough isolates ofL. reuteriare of intestinal origin.
