Shigella also produce a number of toxins (Shiga toxin and others) that increase the amount of fluid secretion by the intestinal tract. This fluid secretion is a major cause of the diarrhea symptoms.
Symptoms can be limited to only mild diarrhea or go on to full-blown dysentery.
The common name for Shigella is Dysentery. This causes a severe, watery diarrhea. A person loses so much water it is fatal. This disease also is caused by an amoeba.
Shigella accounts for about 10% of diarrhea illness in travelers to Mexico, South America, and the tropics.
Shigella are extremely infectious bacteria, and ingestion of just 10 organisms is enough to cause severe diarrhea and dehydration.
Shigella accounts for 10-20% of all cases of diarrhea worldwide, and in any given year infects over 140 million persons and kills 600,000, mostly children and the elderly.
Dysentery is often referred to as "bloody diarrhea" due to its characteristic symptom of blood in the stool. Other names include "amoebic dysentery" when caused by the parasite Entamoeba histolytica and "bacillary dysentery" for cases caused by bacteria such as Shigella. It is also sometimes colloquially referred to as "summer diarrhea" in certain contexts.
