List and compare the three types of amebiasis
What will be an ideal response?
The three types of amebiasis differ in the virulence factors of the infecting strain of Entamoeba histolytica and the state of health of the host. The least severe form of amebiasis is luminal amebiasis in which the parasite remains in the open space of the intestine. Luminal amebiasis is asymptomatic in healthy individuals. When the strain of E. histolytica produces adhesion proteins, proteases, or other important virulence factors, they can invade the bloodstream and peritoneal cavity, producing the more serious forms of amebiasis. Amebic dysentery is characterized by severe diarrhea, bloody, mucus-containing stools, and colitis. Invasive extraintestinal amebiasis occurs when E. histolytica spreads to other areas of the body and forms necrotic lesions in the liver, lungs, kidneys, and other vital organs. It is the most severe form of the disease and can even be fatal.
