Galactose and N-acetyl-D-galactosamine-inhibitable lectin of Entamoeba histolytica has roles in pathogenicity and induction of protective immunity in rodent models of amoebiasis. Recently, the intermediate subunit of the lectin, Igl1, of E. histolytica has been shown to have hemolytic activity. However, the corresponding lectin is also expressed in a non-virulent species, Entamoeba dispar, and ...
Using ultrastructural cytochemical techniques we have found differences in the distribution of surface coat components between the invasive protozoan parasite Entamoeba histolytica and the non-invasive Entamoeba dispar. Carbohydrate-containing components and anionic sites in the cell surface of both species were detected by staining with ruthenium red and cationized ferritin, respectively. Ruth...
For over 30 years it has been established that the Entamoeba histolytica protozoan included two biologically and genetically different species, one with a pathogenic phenotype called E. histolytica and the other with a non-pathogenic phenotype called Entamoeba dispar. Both of these amoebae species can infect humans. E. histolytica has been considered as a potential pathogen that can cause serio...
PRELIMINARY COMPARATIVE STUDY OF ENTAMOEBA HISTOLYTICA AND ENTAMOEBA DISPAR BY PCR TECHNIQUE IN IRAN
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...
Introduction The intestinal protozoa Entamoeba histolytica, Giardia lamblia, and Cryptosporidium spp. are the causative agents of giardiasis, amebiasis, and cryptosporidiosis, respectively. Adequate knowledge of the geographical distribution of parasites and the demographic variables that influence their prevalence is important for effective control of infection in at-risk populations. Methods ...
Specific identification of Entamoeba spp. in clinical specimens is an important confirmatory diagnostic step in the management of patients who may be infected with Entamoeba histolytica, the species that causes clinical amebiasis. Distinct real-time PCR protocols have recently been published for identification of E. histolytica and differentiation from the morphologically identical nonpathogeni...
Amoebiasis, a disease caused by Entamoeba histolytica, is usually diagnosed by microscopic examination, which does not differentiate the morphologically identical species of the E. histolytica/E. dispar complex. Furthermore, morphologically similar species such as Entamoeba hartmanni contribute to misidentification. Therefore, there is a need for more sensitive and specific methods. This study ...
