Laboratory diagnostic techniques for entamoeba

Entamoeba histolytica is the leading cause diarrhoea in developing country. The amebas colonize the gut, interact with bacterial flora, adhere to and lyse tissue, and combat the host's inflammatory response. It leads to noninvasive lesion to intestinal lesion causing diaahoea and extraintestinal invasive lesion leading to liver abcess, peritoneal abcess, lung abcess, rarely cerebral abcess. Diagnosis of intestinal amebiasis rests on microcopy that is finding either trophozoites in diarrheal stools or cysts in formed stools. Antigen and antibody detection of E. histolytica, nucleic acid detection of this protozoan. Other molecular test that are very sensitive but they are very expensive.
