Entamoeba histolytica is the causative agent of human intestinal and liver amebiasis. The extraordinary phagocytic activity of E. histolytica trophozoites has been accepted as one of the virulence mechanisms responsible for their invasive capacity. The recognition of the noninvasive Entamoeba dispar as a different species has raised the question as to whether the lack of pathogenic potential of...

The prevalence of intestinal parasitic infection was studied by stool examination in institutionalized and non-institutionalized Thai people with mental handicaps. It was found that the prevalence of infection was much higher in institutionalized (57.6%) than in non-institutionalized people (7.5%). The common parasites found in institutionalized people were Trichuris trichiura (29.7%), Entamoeb...

background: differential diagnosis of two protozoan parasites entamoeba histolytica and e. dispar is of great clinical and epide miologi cal importance, but except in the case of haematophagous trophozoites in acute dysentery, it is not possible to differ entiate them by microscopy. the present study was carried out from february 2005 to july 2006 in order to determine the preva lence of e. his...

BACKGROUND A number of methods for detecting diversity in Entamoeba have been described over the years. In the present study the genetic polymorphism of noncoding locus A-L was analyzed using PCR and sequencing in order to clarify the genotypic differences among E. dispar isolates. METHODS A total of 28 E. dispar from patients with gastrointestinal symptoms were determined and the genomic DNA...

BACKGROUND Diarrhoea is the leading cause of morbidity and mortality in children under 5 years of age in developing countries, including Ethiopia. It is caused by a wide range of pathogens, including parasites, bacteria and viruses. The aim of this study was to determine the prevalence of infection with intestinal parasites (IPs) (and types) among children under 5 years of age with diarrhoeal d...

The causative agent of amoebiasis is currently attributed to two distinct species (E. histolytica and E. dispar). The aim of this study was to differentiate these species by PCR in stool samples. Isolated genomic DNA was amplified by PCR and band products of 101 bp (E. dispar) were obtained. All seven stool samples were found to be E. dispar, not E. histolytica. Our results demonstrated the sig...

Entamoeba histolytica is a protozoan parasite that causes amebic dysentery and liver abscess. The disease is common in tropical regions of the world where hygiene and sanitation is often approximate. The epidemiology of E. histolytica has been studied around the world. However, there is a dearth of comprehensive literature on the epidemiology of this pathogen as well as its pathogenicity in the...
