Study Notes
Entamoeba Histolytica: Parasitic Characteristics and Clinical Manifestations
- The cystic form of Entamoeba histolytica serves for the parasite's survival in adverse living conditions, and it is the invasive form of some parasites.
- The types of reproduction of Protozoa include asexual (binary fission, multiple fission, endodyogeny) and sexual (conjugation in Balantidium coli; gametogony in Sporozoa like genus Plasmodium).
- Phylum Sarcomastigophora includes two subphyla: Mastigophora and Sarcodina, with 7 species of amoebae inhabiting the gastrointestinal tract of humans.
- Entamoeba histolytica is a parasitic amoeba that primarily infects the large intestine of humans, causing invasive amebiasis which leads to disabling illness and an estimated 50,000 deaths annually, mostly in tropical regions.
- The morphology of E. histolytica occurs in three forms: forma magna, forma minuta, and forma cystica.
- The life cycle of E. histolytica involves the acquisition of infection by swallowing mature cysts, excystation in the small intestine, migration of adult trophozoites to the large intestine, and the formation and secretion of cysts in infected individuals.
- In individuals with reduced biological resistance, the forma minuta can turn into the invasive forma magna, causing local damages and potentially reaching other organs.
- Clinical features of E. histolytica infection include amebic dysentery, expansion of ulcers in the intestines, and extraintestinal manifestations such as abscesses in different organs.
- Diagnosis of amebiasis involves microscopy for stool examination and serology for antibody and amebic antigen detection.
- Prophylaxis of amebiasis includes purification and control of water reservoirs, preservation of food products from houseflies, and good personal hygiene.
- Entamoeba coli, a related species, exists as a vegetative form in the large intestine and is discarded outside with feces like cysts, but it is a commensal and does not cause disease, unlike E. histolytica.
- Differences between Entamoeba coli and Entamoeba histolytica include size, mobility, presence of erythrocytes, and the clinical impact on the host.
