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.
Fecal microbe transplants from healthy donors can treat patients with recurrent Clostridium difficile infections. However, after tens of thousands transplants,
According to researchers at ETH Zurich, when the gut is already populated by a closely similar strain of Salmonella bacteria, it only requires the capacity to use a single other food source for the bacteria to flourish.
Gastrointestinal and digestive issues impact roughly 3 million people across the United States alone, and that number is growing.
According to a recent JAMA study by scientists at the University of Pittsburgh and UPMC, a nasal swab to screen for three types of bacteria can reveal whether or not antibiotics are likely to be beneficial in children with suspected sinusitis.
In Europe, Clostridioides difficile infection results in severe diarrhea and leads to the death of around 20,000 patients, every year. It is one of the most common hospital-acquired infections.
Clostridioides difficile (C. difficile) is a bacterium that can infect the large intestine, with symptoms ranging from diarrhea to life-threatening colon damage.
Scientists have collaborated to produce the first gene-edited calf with resistance to bovine viral diarrhea virus (BVDV), a virus that costs the U.S. cattle sector billions of dollars annually.
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.
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.
Shigella bacteria can infect humans but not mice. In the March 29 issue of Nature, a team from UConn Health explains why. Their findings may explain the multifariousness of a key weapon of our immune system.
According to the World Health Organization, enterotoxigenic Escherichia coli (ETEC) bacteria are the most common cause of traveler’s diarrhea and cause the greatest number of known community-acquired cases of childhood diarrhea in the developing world.
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.
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.
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.
A new study led by researchers at Harvard Medical School illuminates how the brain becomes aware that there is an infection in the body.
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.
The gut microbiota contains trillions of bacteria that can promote health or cause disease under different conditions.
A research team guided by Professor Xiang David Li of The University of Hong Kong’s (HKU) Department of Chemistry created a new chemical tool to unveil how bacteria adjust to the host environment and control host cells.
A genomic study of a sustained, multidrug-resistant Shigellosis outbreak in Seattle enabled scientists to retrace its origin and spread.
An international consortium co-led by Vanderbilt University Medical Center immunogeneticist Rubén Martínez-Barricarte, PhD, has discovered a new genetic disorder that causes immunodeficiency and profound susceptibility to opportunistic infections including life-threatening fungal pneumonia.
