Amoebiasis, or amoebic dysentery, is an infection of the intestines caused by a parasitic amoeba Entamoeba histolytica. [3] [4] Amoebiasis can be present with no, mild, or severe symptoms. [2] Symptoms may include lethargy, loss of weight, colonic ulcerations, abdominal pain, diarrhea, or bloody diarrhea.
Hookworm is closely associated with poverty because it is most often found in impoverished areas, and its symptoms promote poverty through the educational and health effects it has on children. [2] It is the leading cause of anemia and undernutrition in developing countries, while being one of the most commonly occurring diseases among poor ...
These symptoms negatively impact nutritional status, including decreased absorption of micronutrients, loss of appetite, weight loss, and intestinal blood loss that can often result in anemia. It may also cause physical and mental disabilities, delayed growth in children, and skin irritation around the anus and vulva. [2]
Poor sanitary conditions are known to increase the risk of contracting amebiasis E. histolytica. [11] In the United States, there is a much higher rate of amebiasis-related mortality in California and Texas (this might be caused by the proximity of those states to E. histolytica-endemic areas, such as Mexico), parts of Latin America, and Asia. [12]
Insufficient data exists, but Shigella is estimated to have caused the death of 34,000 children under the age of five in 2013, and 40,000 deaths in people over five years of age. [25] Amoebiasis infects over 50 million people each year, of whom 50,000 die (one per thousand).
Entamoeba histolytica is a pathogenic parasite known to cause amoebiasis, which is the third leading cause of parasitic deaths. [20] It is diagnosed by the assessment of stool samples. [ 21 ] Amoebiasis is caused by the ingestion of food or water contaminated with feces or other bodily wastes of an infected person, which contain cysts, the ...
As many individuals are asymptomatic carriers of D. fragilis, pathogenic and nonpathogenic variants are proposed to exist.A study of D. fragilis isolates from 60 individuals with symptomatic infection in Sydney, Australia, found all were infected with the same genotype, [4] which is the most common worldwide, but differed from the genotype first described from a North American isolate and ...
Entamoeba histolytica is the pathogen responsible for invasive 'amoebiasis' (which includes amoebic dysentery and amoebic liver abscesses). Others such as Entamoeba coli (not to be confused with Escherichia coli ) and Entamoeba dispar [ 3 ] are harmless.
