Diarrhea News and Research

RSS

Diarrhea is loose, watery stools. A person with diarrhea typically passes stool more than three times a day. People with diarrhea may pass more than a quart of stool a day. Acute diarrhea is a common problem that usually lasts 1 or 2 days and goes away on its own without special treatment. Prolonged diarrhea persisting for more than 2 days may be a sign of a more serious problem and poses the risk of dehydration. Chronic diarrhea may be a feature of a chronic disease.

Diarrhea can cause dehydration, which means the body lacks enough fluid to function properly. Dehydration is particularly dangerous in children and older people, and it must be treated promptly to avoid serious health problems.

How Bacteria Take Action to Break Out of Dormancy

Solving a riddle that has confounded biologists since bacterial spores -; inert, sleeping bacteria -; were first described more than 150 years ago, researchers at Harvard Medical School have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life.

Food-Poisoning Bacteria Create Syringe-Like Structures to Inject Toxins Into Intestinal Cells

Researchers at UT Southwestern Medical Center have discovered how a bacterium that infects people after they eat raw or undercooked shellfish creates syringe-like structures to inject its toxins into intestinal cells.

New compound may offer a way to prevent serious C. diff infections

Each year, about 500,000 people in the U.S. deal with gastrointestinal infections from Clostridioides difficile (C. diff), and more than 20,000 die from these infections.

The protein synthesis mechanism in the Giardia parasite

Cryo-electron microscopy was employed by Uppsala University researchers to reveal information on the protein synthesis mechanism in the parasite Giardia intestinalis, which causes diarrhea. The new findings could help in the development of specific medicines to combat Giardia and other protozoan parasites.

Rice biologists embark on a three-year project to create genetically encoded antibiotics

Synthetic biologists at Rice University are embarking on a three-year project to create "genetically encoded antibiotics," strands of RNA that bacteria will readily copy and share that will selectively kill only disease-causing, pathogenic bacteria.

Role of probiotics and functional materials in the treatment of intestinal inflammation

Maintenance of sulfomucin is a key end point in the treatment of diarrhea and inflammatory bowel disease (IBD). However, the mechanism underlying the microbial sense to sulfomucin are poorly understood, and to date, there are no therapies targeting the secretion and maturation of sulfomucin in IBD. Considering the important role of gut microbiota in host immune regulation, maintain sulfomucin by modulating the gut microbiota is inspired.
