BACKGROUND The World Health Organization estimates that about 3.5 billion people worldwide are affected by intestinal parasitic infections. Reports have already emphasized the role of immigrants in outbreaks of parasitic diseases in industrialized countries. With the mass influx of immigrants to Qatar, patent intestinal parasitic infections have been observed. Herein, the prevalence of intestin...

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 dn...

Objective: To assess the magnitude of Entamoeba histolytica/ Entamoeba dispar infestation and to study some socio-demographic correlates in relation to parasitic infestation in the study subjects. Material & Methods: A cross sectional epidemiological study was carried out in West Bengal, India among rural population of two districts. Stool samples from selected study subjects of all age groups ...

We used the polymerase chain reaction (PCR) to study the distribution of Entamoeba histolytica and E. dispar in 1,872 individuals in 14 communities in the northern Philippines. Here we report a field study using a DNA extraction protocol from formalin-fixed stool specimens as previously reported. This assay detected 137 stools (7.318%) containing E. dispar and 18 stools (0.961%) containing E. h...

The human large intestine can harbor two morphologically similar amoebae; the invasive Entamoeba histolytica and the non-invasive Entamoeba dispar. Whereas E. histolytica can produce intestinal and extra-intestinal lesions, E. dispar is present in non-symptomatic carriers. Although biochemical, genetic and proteomic studies have identified clear differences between these Entamoebae, it has beco...

Entamoeba histolytica infection is one of the significantly common pathogenic protozoa encountered in Saudi Arabia. Previous reports did not distinguish between E. histolytica and E. dispar as differential diagnosis is essential both for treatment decision and public health knowledge. Studies suggested that stool antigen assays are more sensitive and specific than microscopy for the diagnosis o...
