Introduction


Background Information

Amoebiasis was first identified by Hippocrates around 300 B.C., in which he described a patient displaying symptoms of fever and dysentery. Throughout the world, amoebiasis is the second leading cause of death from a parasitic disease with an estimated 70,000 deaths per year. However, most of these cases occur in the developing world. Amoebiasis is a gastrointestinal infection due to the amoeba,
Entamoeba histolytica. Although it accounts for a large number of deaths every year, about 90% of the people exposed to
E. histolytica are asymptomatic.

Entamoeba histolytica Lifecycle



Prognosis/Treatment


"E. histolytica contains proteolytic enzymes (collagenase and neutral proteases) and cysteine proteases, which presumably facilitate its tissue invasion. The parasite also elaborates a range of enzymes on the amebic surface, including membrane-associated neuraminidase and β-glucosaminidase (166, 223, 234)."

Therapy Developments of Amoebiasis

Section 2

Development of Diagnoses Methods It is important to have as precise methods as possible in detecting E. histolytica in order to determine the extent of the amoebiasis infection. Furthermore, the more that is understood about E. histolytic, researchers are better to develop treatments.

Microscopy/Biochemical Methods Microscopy has historically been the most prominent method of detecting E. histolytica. However, researchers are now discovering that it is difficult to to detect morphological differences among similar protozoa. There is another emerging problem becoming apparent with diagnosing amoebiasis with microscopy: ELISA

Conclusion

Overall text length should be at least 1,000 words (before counting references), with at least 2 images. Include at least 5 references under Reference section.
