C. difficile exploits a host metabolite produced during toxin-mediated disease.

Nature 2021 Apr 28. Epub 2021 Apr 28.

Department of Microbiology and Immunology, Stanford University School of Medicine, Stanford, CA, USA.

Several enteric pathogens can gain specific metabolic advantages over other members of the microbiota by inducing host pathology and inflammation. The pathogen Clostridium difficile is responsible for a toxin-mediated colitis that causes 450,000 infections and 15,000 deaths in the United States each year; however, the molecular mechanisms by which C. difficile benefits from this pathology remain unclear.

Long-Term Infectious Complications of Kidney Transplantation.

Clin J Am Soc Nephrol 2021 Apr 20. Epub 2021 Apr 20.

Division of Pediatric Infectious Diseases, Cincinnati Children's Hospital Medical Center and University of Cincinnati, Cincinnati, Ohio

Infections remain a common complication of solid-organ transplantation. Most infections in the first month after transplant are typically health care-associated infections, whereas late infections, beyond 6-12 months, are community-acquired infections. Opportunistic infections most frequently present in the first 12 months post-transplant and can be modulated on prior exposures and use of prophylaxis. Read More

Colocutaneous fistula following infection managed as an 'autocolostomy': a novel approach to a recognised complication.

BMJ Case Rep 2021 Apr 16;14(4). Epub 2021 Apr 16.

General Surgery, The Dudley Group NHS Foundation Trust, Dudley, UK

Colocutaneous fistula is a rare entity in colorectal disease. We present a case of colocutaneous fistula in a patient whose postoperative course following a laparoscopic anterior resection for sigmoid cancer was complicated by colitis. During the follow-up period, it was found that his bowel contents were preferentially discharging through this fistula which had taken up the role of an 'autocolostomy'. Read More

Department of Microbiology and Infectious Diseases, Toho University School of Medicine, Tokyo 143-8540, Japan.

infection (CDI) causes toxin-mediated enteropathy, such as antibiotic-associated diarrhoea and pseudomembranous colitis. Rho-glucosylating toxin A (TcdA) and toxin B (TcdB) have been clearly implicated in pathogenesis, whereas the virulence of binary toxin (CDT) is still debated. We hypothesized that CDT is involved in the host immune response and plays a pivotal role in establishing virulence by modulating pro-inflammatory cytokine production; this is achieved through the integral Toll-like receptor (TLR) signalling pathways.

Protection from Lethal Clostridioides difficile Infection via Intraspecies Competition for Cogerminant.

mBio 2021 03 30;12(2). Epub 2021 Mar 30.

Department of Microbiology and Immunology, University of Michigan Medical School, Ann Arbor, Michigan, USA

, a Gram-positive, spore-forming bacterium, is the primary cause of infectious nosocomial diarrhea. Antibiotics are a major risk factor for infection (CDI), as they disrupt the gut microbial community, enabling increased germination of spores and growth of vegetative To date, the only single-species bacterial preparation that has demonstrated efficacy in reducing recurrent CDI in humans is nontoxigenic Using multiple infection models, we determined that precolonization with a less virulent strain is sufficient to protect from challenge with a lethal strain of , surprisingly even in the absence of adaptive immunity. Additionally, we showed that protection is dependent on high levels of colonization by the less virulent strain and that it is mediated by exclusion of the invading strain. Read More

Colonization resistance (CR), the ability to block infections by potentially harmful microbes, is a fundamental function of host-associated microbial communities and highly conserved between animals and humans. Environmental factors such as antibiotics and diet can disturb microbial community composition and thereby predispose to opportunistic infections. The most prominent is Clostridioides difficile, the causative agent of diarrhea and pseudomembranous colitis. Read More

Gut microbiome and infection: a closer look at the microscopic interface.

Therap Adv Gastroenterol 2021 23;14:1756284821994736. Epub 2021 Feb 23.

Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN, USA.

The pathogenesis of infection (CDI) was recognized with its link to the use of antimicrobials. Antimicrobials significantly alter gut microbiota structure and composition, which led to the discovery of the association of this gut perturbation with the development of CDI. A number of factors implicated in its pathogenesis, such as advancing age, proton-pump inhibitors, and gastrointestinal diseases, are linked to gut microbiota perturbations. Read More

Институт химической биологии и фундаментальной медицины Сибирского отделения Российской академии наук, Новосибирск, Россия.

Intestinal human microbiota is a dynamic system that is under the pressures of its host organism and external factors. Microbiota disruption caused by these factors can lead to severe diseases including inflammatory and oncological diseases of the gastrointestinal tract. One of the possible approaches in managing the intestinal microbiota is fecal microbiota transplantation (FT) - transfer of the microbiota from the stool of a healthy donor to the intestinal tract of a recipient patient.

Loss of Interleukin-10 (IL-10) Signaling Promotes IL-22-Dependent Host Defenses against Acute Clostridioides difficile Infection.

Department of Microbiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA

Infection with the bacterial pathogen causes severe damage to the intestinal epithelium that elicits a robust inflammatory response. Markers of intestinal inflammation accurately predict clinical disease, however, the extent to which host-derived proinflammatory mediators drive pathogenesis versus promote host protective mechanisms remains elusive. In this report, we employed mice as a model of spontaneous colitis to examine the impact of constitutive intestinal immune activation, independent of infection, on disease pathogenesis. Read More
