Amoebic infection, also known as amoebiasis or entamoebiases is characterized as a infection caused by any of the amoebas of the Entamoeba group. Most infections are asymptomatic, but they mostly cause intestinal diseases and infections. Symptoms happen by the infection by Entamoeba histolytica. Symptoms include abdominal pain, loose stool, mild diarrhoea, stomach pain, bloody diarrhea or severe colitis. But some people may not experience the symptoms, while having amebiasis.

WHO IS A RISK FOR AMOEBIC INFECTION?

Amoebic infection is mostly common those countries having poor sanitation. The Merck Manual states that amoebic infection is mostly common in the part of South and Central America, Indian subcontinent and some parts of Africa. People living in United State are at the lowest risk of developing amoebic infection.

People at the highest risk of amoebic infection include:

  • People who have traveled to areas with low sanitation
  • Immigrants from tropical countries with poor sanitation
  • People who reside in areas with poor sanitary conditions, including prisons.
  • People having weakened immune systems and poor health.
Causes of Amoebic Infection :

Entamoeba histolytica is a one celled protozoan that mostly invades the when a person takes food or water contaminated with E.histolytica. It also enters the body by direct contact with dump of animal, human beings and birds. The microscopic cysts of E. Histolytica are present ir  water, soil and air that’s been contaminated with infected feces. Food handlers mostly transmit cysts. It is also transmitted through anal.

When cysts enter the body through any ways, they reside in the digestive tract. Then they start releasing a parasite called trophozite. This parasite starts reproducing inside the digestive tract after which it migrates to the intestine. This can cause colitis, diarrhea and the destruction of tissue.

After trophozites enters the intestinal walls, they pass into the blood and invade to other organs. If they reach a organ, they may cause:

  • Severe illness
  • Abscesses
  • Infections
  • Death
