Bile acids, which are altered by bacteria normally living in the large intestine, inhibit the growth of Clostridium difficile, new research indicates. The work sheds light on the ways in which some commonly used antibiotics can promote C. diff infections by killing off the bile acid-altering microbes.

This Medical News article discusses whether trehalose, a sugar manufactured from cornstarch used to sweeten and texturize foods, has contributed to the emergence of epidemic strains of Clostridium difficile infection (CDI).

The increasing frequency and severity of healthcare-associated outbreaks caused by bacterium Clostridium difficile have been linked to the widely used...

Two hypervirulent ribotypes of the enteric pathogen Clostridium difficile, RT027 and RT078, have independently acquired unique mechanisms to metabolize low concentrations of the disaccharide trehalose, suggesting a correlation between the emergence of these ribotypes and the widespread adoption of trehalose in the human diet.

Clostridium difficile disease has recently increased to become a dominant nosocomial pathogen in North America and Europe, although little is known about what has driven this emergence. Here we show that two epidemic ribotypes (RT027 and RT078) have acquired unique mechanisms to metabolize low conce …

Abstract. Background. Clostridium difficile is a primary cause of antibiotic-associated diarrhea that typically develops when gut microbiota is altered. Convent

c ribotypes of C. difficile harbour mutations or have acquired extra genes that mean these strains can utilize lower concentrations of bioavailable trehalose, providing a competitive metabolic advantage in some CDI animal models. By contrast, evidence has emerged to show that trehalose-induced microbiota changes can help protect/reduce CDI in other models. In addition, C. difficile trehalose metabolic variants are widespread among epidemic and nonepidemic ribotypes alike, and the occurrence of these trehalose variants was not associated with increase disease severity or mortality. Summary Currently, there is no proven causal association between the incidence or severity of human CDI and the presence of trehalose metabolism variants. Furthermore, microbial metabolism reduces trehalose bioavailability, potentially removing this competitive advantage for C. difficile trehalose metabolism variants. Taken together, trehalose consumed as part of a normal diet has no increased risk of CDI....

Clostridioides difficile infection (CDI) has emerged as a major health problem worldwide. A major risk factor for disease development is prior antibiotic use, which disrupts the normal gut microbiota by altering its composition and the gut’s metabolic functions, leading to the loss of colonization resistance and subsequent CDI. Data from human studies have shown that the presence of C. difficile, either as a colonizer or as a pathogen, is associated with a decreased level of gut microbiota diversity. The investigation of the gut’s microbial communities, in both healthy subjects and patients with CDI, elucidate the role of microbiota and improve the current biotherapeutics for patients with CDI. Fecal microbiota transplantation has a major role in managing CDI, aiming at re-establishing colonization resistance in the host gastrointestinal tract by replenishing the gut microbiota. New techniques, such as post-genomics, proteomics and metabolomics analyses, can possibly determine in the future the way in which C. difficile eradicates colonization resistance, paving the way for the development of new, more successful treatments and prevention. The aim of the present review is to present recent data concerning the human gut microbiota with a focus on its important role in health and disease.

Clostridium (C.) difficile-infection (CDI), a nosocomial gastrointestinal disorder, is of growing concern due to its rapid rise in recent years. Antibiotic therapy of CDI is associated with disrupted metabolic function and altered gut microbiota. The use of probiotics as an adjunct is being studied extensively due to their potential to modulate metabolic functions and the gut microbiota. In the present study, we assessed the ability of several single strain probiotics and a probiotic mixture to change the metabolic functions of normal and C. difficile-infected fecal samples. The production of short-chain fatty acids (SCFAs), hydrogen sulfide (H2S), and ammonia was measured, and changes in microbial composition were assessed by 16S rRNA gene amplicon sequencing. The C. difficile-infection in fecal samples resulted in a significant decrease (p < 0.05) in SCFA and H2S production, with a lower microbial alpha diversity. All probiotic treatments were associated with significantly increased (p < 0.05) levels of SCFAs and restored H2S levels. Probiotics showed no effect on microbial composition of either normal or C. difficile-infected fecal samples. These findings indicate that probiotics may be useful to improve the metabolic dysregulation associated with C. difficile infection.
