Background: The present study was conducted approximately 40 years ago, but its results have not been released. At the time of this study, the importance of the gut microbiota was not fully understood.

Methods: rodents, as one of the major reservoirs of bacterium in Iran, were compared in a disease endemic area (Akanlu, Hamadan, western Iran) and a non-endemic zone (Telo, Tehran, Iran) from 1977 to 1981.

Results: This study was able to transmit the resistance to to other rodents creatively by using and transferring gut microbiota.

Conclusion: The study indicated for the first time that the gut microbiota could affect the sensitivity to plague in in Telo.

Disturbances of the intestinal barrier enabling bacterial translocation exacerbate alcoholic liver disease (ALD). GG (LGG) has been shown to exert beneficial effects in gut dysbiosis and chronic liver disease. The current study assessed the combined effects of LGG and metformin, which play roles in anti-inflammatory and immunoregulatory processes, in alcohol-induced liver disease mice.

Inflammatory bowel disease is a chronic inflammatory condition predominantly affecting the intestines, encompassing both ulcerative colitis and Crohn disease (CD). As one of the most common gastrointestinal disorders, CD's pathogenesis is closely linked with the intestinal microbiota. Recently, fecal microbiota transplantation (FMT) has gained attention as a potential treatment for CD, with the effective reestablishment of intestinal microecology considered a crucial mechanism of FMT therapy.

Introduction: Intestinal constipation is a substantive global health concern, significantly impairing patient quality of life. An emerging view is that the gut microbiota plays a critical role in intestinal function, and probiotics could offer therapeutic benefits. This study aims to consolidate evidence from randomized controlled trials (RCTs) that assess the effectiveness of probiotics in modulating microbiota and ameliorating symptoms of constipation.

Insect diversity is closely linked to the evolution of phytophagy, with most phytophagous insects showing a strong degree of specialisation for specific host plants. Recent studies suggest that the insect gut microbiome might be crucial in facilitating the dietary (host plant) range. This requires the formation of stable insect-microbiome associations, but it remains largely unclear which processes govern the assembly of insect microbiomes.

Protocol for oral fecal gavage to reshape the gut microbiota in mice.

Fecal microbiota transplantation (FMT) is clinically applied, while oral FMT (oral fecal gavage [OFG]) is preferred for experimental mice. Here, we present a protocol for OFG in antibiotic-pretreated mice, demonstrating the progressive, time-dependent evolution of the gut microbiota in the recipients. We describe steps for fecal sample collection and preparation procedures, oral gavage, and monitoring gut microbiota changes.
