Clostridioides difficile, also known more commonly as C. diff, accounts for 10 to 20% of antibiotic-associated diarrhea cases, because the antibiotics administered for the treatment of certain disease processes such as inflammatory colitis also inadvertently kill a large portion of the gut flora, the normal flora that is usually present within the bowel.
Transmission is fecal-oral and is remarkable for the small number of organisms that may cause disease (10 ingested organisms cause illness in 10% of volunteers, and 500 organisms cause disease in 50% of volunteers). Shigella bacteria invade the intestinal mucosal cells but do not usually go beyond the lamina propria. Dysentery is caused when ...
Signs and symptoms of CDI range from mild diarrhea to severe life-threatening inflammation of the colon. [16]In adults, a clinical prediction rule found the best signs to be significant diarrhea ("new onset of more than three partially formed or watery stools per 24-hour period"), recent antibiotic exposure, abdominal pain, fever (up to 40.5 °C or 105 °F), and a distinctive foul odor to the ...

The results might not come as too much of a surprise: Clorox took the top spot for disinfectant wipes. Clorox “is durable, effective, [and] it kills germs,” as one survey respondent explained.
Dr. Leana Wen: Norovirus is the leading cause of foodborne illness in the US. According to the CDC, it is responsible for 19 million to 21 million illnesses every year. It results in over 2.2 ...
First, the excessive bacterial concentrations can cause direct inflammation of the small bowel cells, leading to an inflammatory diarrhea. The malabsorption of lipids, proteins and carbohydrates may cause poorly digestible products to enter into the colon. This can cause an osmotic diarrhea or stimulate the colonic cells to cause a secretory ...
