Which microbe causes amoebic dysentery?
Which microbe causes amoebic dysentery?
amoebic dysentery or amoebiasis, which is caused by an amoeba (single celled parasite) called Entamoeba histolytica, which is mainly found in tropical areas; this type of dysentery is usually picked up abroad.
What animals affect dysentery?
histolytica include monkeys, dogs, and pigs, but these animals play a minor role in transmission in comparison to humans, who are the principal reservoir of infection. Infection usually occurs by either direct person-to-person transmission of cysts or by cysts contaminating food or water.
Which bacteria causes bacillary dysentery?
Bacillary dysentery is an intestinal infection caused by a group of Shigella bacteria which can be found in the human gut. Infection by Shigella may be asymptomatic or only cause mild illness.
What causes battlefield dysentery?

What are the causes of amoeba?
Amebiasis (am-uh-BYE-eh-sis) is an infection of the intestines with a parasite called Entamoeba histolytica (E. histolytica). The parasite is an amoeba (uh-MEE-buh), a single-celled organism. People can get this parasite by eating or drinking something that’s contaminated with it.
How does Shigella cause diarrhea?
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 amoebic and bacillary dysentery?
There are two main types of dysentery. The first type, amoebic dysentery or intestinal amoebiasis, is caused by a single-celled, microscopic parasite living in the large bowel. The second type, bacillary dysentery, is caused by invasive bacteria. Both kinds of dysentery occur mostly in hot countries.
What is the causative agent of dysentery E coli?

What is the best medicine for dysentery?
Amebic dysentery is treated with metronidazole (Flagyl) or tinidazole (Tindamax). These drugs kill the parasites. In some cases, a follow-up drug is given to make sure all the parasites are gone. In severe cases, your doctor may recommend an intravenous (IV) drip to replace fluids and prevent dehydration.
