Amoebic dysentery caused by Entamoeba histolytica results in diarrhea transmitted through contaminated food or drink, with the parasite invading the colon lining and potentially leading to severe symptoms like blood in the stool and affecting other organs. Symptoms include abdominal pain and mucus in the feces, with the parasite's life cycle involving cysts entering the body, developing into trophozoites in the colon, and multiplying through binary fission to continue the cycle of infection.

Insights

  • Entamoeba histolytica causes amoebic dysentery by invading the colon's mucous lining, destroying cells, and potentially spreading to other organs, leading to severe symptoms like blood in stool and affecting organs such as the lungs, liver, and brain.
  • The transmission of amoebic dysentery occurs through contaminated food or drink containing cysts of the parasite, which enter the body, develop into trophozoites in the colon, multiply, and form more cysts, continuing the cycle of infection through fecal excretion.

Parasitic amoebic dysentery: transmission and symptoms

  • Amoebic dysentery is caused by the parasite Entamoeba histolytica, leading to diarrhea in humans. The disease is transmitted through contaminated food or drink containing cysts of the parasite.
  • The life cycle of Entamoeba histolytica involves the cysts entering the body through the mouth, traveling through the gastrointestinal tract, and developing into trophozoites in the colon. Trophozoites multiply through binary fission, leading to the formation of more cysts that are excreted in feces, continuing the cycle of infection.
  • Invasive amoebic dysentery involves the parasite invading the mucous lining of the colon, destroying epithelial cells, and potentially entering the bloodstream, causing severe symptoms such as blood in the stool and affecting various organs like the lungs, liver, and brain. Symptoms of the disease include abdominal pain and mucus in the feces.
