it has been suggested that two distinct species exist within what was originally known as entamoeba histolytica and e. dispar. these are entamoeba dispar for the nonpathogenic and e. histolytica for the pathogenic fonn. differentiation of these two organisms is of great clinical importance since they are morphologically indistinguishable and both fonns can infect the human intestinal cavity. a ...

Amebiasis is one of the twenty major causes of disease in Mexico; however, the diagnosis is difficult due to limitations of conventional microscopy-based techniques. In this study, we analyzed stool samples using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) to differentiate between Entamoeba histolytica (pathogenic) and E. dispar (non-pathogenic). The target for ...

In this study, a single-step duplex polymerase chain reaction procedure was developed for rapid, specific and sensitive identification of Entamoeba histolytica and for its diagnostic differentiation from E. dispar. Specific oligonucleotide primers were combined for the amplification of a cysteine proteinase 5 gene target sequence of 242 bp, present only in E. histolytica. Additionally, another ...

aim : the present study was performed in order to differentiate e. histolytica and e. dispar in children from gorgan city, using a pcr method. background : differential detection of two morphologically indistinguishable protozoan parasites entamoeba histolytica and e. dispar has a great clinical and epidemiological importance because of potential invasive pathogenic e. histolytica and non-invas...

Entamoeba histolytica cells, the cause of amoebic dysentery, are highly motile, and this motility is an essential feature of the pathogenesis and morbidity of amoebiasis. However, the control of E. histolytica motility within the gut and during invasion is poorly understood. We have used an improved chemotaxis assay to identify the key extracellular signals mediating Entamoeba chemotaxis. The d...

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...
