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.
E. histolytica, as its name suggests (histo–lytic = tissue destroying), is pathogenic; infection can be asymptomatic, or it can lead to amoebic dysentery or amoebic liver abscess. [6] [7] Symptoms can include fulminating dysentery, bloody diarrhea, weight loss, fatigue, abdominal pain, and amoeboma.
Amoebiasis, also known as amoebic dysentery, is caused by an infection from the amoeba Entamoeba histolytica, [21] which is found mainly in tropical areas. [22] Proper treatment of the underlying infection of amoebic dysentery is important; insufficiently treated amoebiasis can lie dormant for years and subsequently lead to severe, potentially ...
Balamuthia mandrillaris can also cause cutaneous amoebiasis, but can prove fatal if the amoeba enters the bloodstream [7] [8] It is characterized by ulcers. Diagnosis of amebiasis cutis calls for high degree of clinical suspicion. This needs to be backed with demonstration of trophozoites from lesions. Unless an early diagnosis can be made such ...
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 ...
The species was first described scientifically by American mycologist Howard James Banker in 1913. [2] Italian Pier Andrea Saccardo placed the species in the genus Hydnum in 1925, [3] while Walter Henry Snell and Esther Amelia Dick placed it in Calodon in 1956; [4] Hydnum peckii (Banker) Sacc. and Calodon peckii Snell & E.A. Dick are synonyms of Hydnellum peckii.
Genitourinary amoebiasis or renal amoebiasis is a rare complication to amoebic liver abscess, which in turn is a complication of amoebiasis.It is believed to result from liver abscesses breaking open, whereupon the amoebas spread through the blood to the new locale.
Despite treatment, re-bleeding occurs in about 7–16% of those with upper GI bleeding. [3] In those with esophageal varices, bleeding occurs in about 5–15% a year and if they have bled once, there is a higher risk of further bleeding within six weeks. [13] Testing and treating H. pylori if found can prevent re-bleeding in those with peptic ...
