Entamoeba dispar, the non-pathogenic species, is 10 times more prevalent than the pathogenic E. histolytica. 29 Clinical presentation with intestinal amebiasis usually takes one of three forms. The first is asymptomatic cyst passage detected in screening stool specimens.

Infection with Entamoeba histolytica has the potential to cause dysentery and extraintestinal disease, whereas E. dispar is considered to be a harmless commensal [1, 2]. The World Health Organization has recommended that “E. histolytica should be specifically identified and, if present, treated; if only E. dispar is identified, treatment is unneces...
Patients with gastrointestinal symptoms (diarrhea, defined as ⩾ loose [conform to the container] bowel movements per day, abdominal pain, weight loss, or bloody stool) or risk factors for E. histolytica/E. dispar complex infection (travel within 6 months, male homosexuality, or immigration from the tropics or subtropics <2 years ago) who presented ...
During the study period, 112 consecutive patients were enrolled (72 males and 40 females). Many patients (33.9%) were asymptomatic; the chief complaints of symptomatic patients were diarrhea (30.4%) and abdominal pain (23.2%). Forty-three percent of subjects were born in areas where amebiasis is endemic (67% of whom were born in Africa or Asia). Ri...
Recent studies in areas of endemicity have suggested that antigen detection assays may be an alternative strategy to identify E. histolytica infection. This is the first study to blindly evaluate all available stool antigen ELISA kits, microscopy, and serology for diagnosis of E. histolytica/E. dispar complex infection in a setting of nonendemicity...

It is a normal bacterium in the intestines and oral mucosa of mammals. In humans they have been implicated in cases of osteomyelitis and endocarditis, for example with the species Veillonella parvula. Veillonella dispar is the most nitrate -reducing bacterium in the oral cavity, which is beneficially anti-bacterial. [2]
The majority of infections restricted to the lumen of the intestine (“luminal amebiasis”) are asymptomatic. Amebic colitis, or invasive intestinal amebiasis, occurs when the mucosa is invaded. Symptoms include severe dysentery and associated complications.
Based on studies using PCR to diagnose amebiasis in nonhuman primates, it appears that E. dispar is more prevalent than E. histolytica. In a survey of 107 chimpanzees, 56% were positive for E. dispar DNA and no samples contained E. histolytica DNA (Tachibana et al., 2000).
Jun 14, 2024 · Intestinal amebiasis is caused by the protozoan Entamoeba histolytica. There are four species of intestinal amebae with identical morphologic characteristics: E. histolytica, E. dispar, E. moshkovskii, and E. bangladeshi [1,2]. Most symptomatic disease is caused by E. histolytica; E. dispar is generally considered nonpathogenic.
Jul 1, 1998 · In the 1970s, however, evidence began to accumulate indicating that Brumpt may have been correct and E. dispar is now accepted as a distinct species. This review introduces the organism's history and briefly summarizes what we currently know about its biology.
