ENTAMOEBA HISTOLYTICA ANTIGEN

Entamoeba histolytica is an intestinal parasite.

Entamoeba histolytica infects approximately a half billion persons worldwide annually. Of these, about 10% become symptomatic and develop colitis and liver abscesses, resulting in a mortality rate estimated between 40,000 and 120,000 persons a year.

Patients infected with pathogenic Entamoeba histolytica may show a wide range of conditions. Some may be asymptomatic; others may show mild diarrhea that develops into bloody diarrhea and eventually fulminant colitis. Approximately 10% of patients with invasive amebiasis develop liver abscesses.
