How is Shigella infection?
The main sign of shigella infection is diarrhea, which often is bloody. Shigella is very contagious. People get infected with shigella when they come in contact with and swallow small amounts of bacteria from the stool of a person who is infected with shigella.
How is Shigella diagnosed?
Infection is diagnosed when a laboratory identifies Shigella in the stool (poop) of an ill person. The test could be a culture that isolates the bacteria or a rapid diagnostic test that detects genetic material of the bacteria.
How does Shigella spread?
Shigella is found in the intestinal tract of infected people, and is spread by eating or drinking food or water contaminated with the bacteria. It can also be spread by direct contact with feces (even with microscopic amounts) from an infected person.
Who is at risk for Shigella?
Young children are the most likely to get a Shigella infection, but people of all ages can be affected. Many outbreaks occur in childcare settings and schools. Infection commonly spreads from young children to their family members and other people in their communities because these bacteria spread easily.
What diseases does Shigella cause?
Shigella bacteria cause an infection called shigellosis. Most people with Shigella infection have diarrhea (sometimes bloody), fever, and stomach cramps. Symptoms usually begin 1–2 days after infection and last 7 days.
Can Shigella cause IBS?
Conclusions. Patients who were infected by Shigella sonnei experienced significantly increased risk of IBS until 3 years after shigellosis, and modestly increased risk until 8 years, but showed similar risk of IBS with uninfected controls at 10 years post-infection.
How does Shigella cause Diarrhoea?
Shigella is relatively resistant to acid in the stomach, and few organisms are required to cause the disease. Once ingested, it multiplies in the small intestine then enters the colon, where it produces shigella enterotoxins and serotype toxin 1, which cause watery or bloody diarrhea.
What is shigellosis?
Related Pages. Shigellosis is an infectious disease caused by a group of bacteria called Shigella (shih-GEHL-uh). Most who are infected with Shigella develop diarrhea, fever, and stomach cramps starting a day or two after they are exposed to the bacteria.
What are the symptoms of Shigella?
Shigella bacteria cause an infection called shigellosis. Most people with Shigella infection have diarrhea (sometimes bloody), fever, and stomach cramps. Symptoms usually begin 1–2 days after infection and last 7 days.
What is the pathophysiology of Enterococcus Shigella infection?
Infection is initiated by ingestion of shigellae (usually via fecal-oral contamination). An early symptom, diarrhea (possibly elicited by enterotoxins and/or cytotoxin), may occur as the organisms pass through the small intestine.
How are shigellae identified in the clinical laboratory?
The identification of shigellae by species in the clinical laboratory is usually accomplished by slide agglutination using commercially available, absorbed rabbit antisera. Pathogenesis
