Where does cholera colonize?

small intestine
To cause the diarrheal disease cholera, Vibrio cholerae must effectively colonize the small intestine. In order to do so, the bacterium needs to successfully travel through the stomach and withstand the presence of agents such as bile and antimicrobial peptides in the intestinal lumen and mucus.

Can you get cholera from shellfish?

A person can get cholera by drinking water or eating food contaminated with the cholera bacterium. Large epidemics are often related to fecal contamination of water supplies or street vended foods. The disease is occasionally spread through eating raw or undercooked shellfish that are naturally contaminated.

What is the pathogenesis of cholera?

V. cholerae is a motile bacterium which is one of the major factors in the pathogenicity. The flagellar antibodies could prevent the invasion of the bacteria by immobilizing them; as well the somatic (O) and flagellar (H) antibodies can cause clumping and lead to arrest of motion of cells.

Where is cholera most commonly found?

Cholera is mostly found in the tropics — in particular Asia, Africa, Latin America, India, and the Middle East.

What is the causative agent of cholera?

An estimated 2.9 million cases and 95,000 deaths occur each year around the world. The infection is often mild or without symptoms, but can be severe. Approximately 1 in 10 people who get sick with cholera will develop severe symptoms such as watery diarrhea, vomiting, and leg cramps.

What happens in cholera?

A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).

What is the difference between cholera and dysentery?

Cholera spreads rapidly in areas where drinking water is contaminated. That was the problem for those on the Oregon Trail just as it was in Haiti. Dysentery is also a diarrheal illness and is often caused by Shigella species (bacillary dysentery) or Entamoeba histolytica (amoebic dysentery).
