“…1 This procedure is cheap and simple, but it has several limitations, such as being incapable of distinguishing between the cysts and trophozoites of the disease-causing species Entamoeba histolytica , the nonpathogenic Entamoeba dispar , and the free-living amoeba Entamoeba moshkovskii . A high prevalence and association of E. moshkovskii with E. histolytica and E. dispar has been reported in young children from Bangladesh 2,3 and E. moshkovskii was recently detected in patients between 31 and 50 years of age presenting with gastrointestinal symptoms in Australia 4 ; therefore, humans may be a true host for this amoeba. This observation has made the differentiation of the three species in clinical samples of great importance, both for diagnosis and for epidemiological studies.…”

Abstract. Multiplex real -time polymerase chain reaction (PCR) was developed for differential detection of Entamoeba histolytica , Entamoeba dispar , and Entamoeba moshkovskii . Specific primers were designed for all three species, and then differentiation of E. histolytica and E. dispar was achieved simultaneously using a hybridization probe and melting curve analysis, whereas E. moshkovskii was detected with a separate probe under the same condition. This assay detected as little as 0.2 pg of E. histolytica DNA and 2 pg each for E. dispar and E. moshkovskii DNA. Thirty-five clinical samples suspected to be E. histolytica infection by microscopy were tested. The results showed 32 positive samples; four samples were E . histolytica and 28 samples were E. dispar . Interestingly, one E. dispar positive sample showed a mixed infection with E. moshkovskii . This is the first report of E. moshkovskii infection from Thailand and this assay is currently the most rapid and sensitive method to differentiate these human amoebas.

“…This species, like the Entamoeba dispar, is nonpathogenic for the man and also belongs to the commensals of the colon. Entamoeba moshkovskii is not cosmopolitan, the literature mentions that it is endemic in Bangladesh, North America and South Africa [6,11,12].…”

“…Asymptomatic invasions of E. histolytica is recorded first and foremost on people living in temperate climates. However, recent scientific reports say that the invasions asymptomatic in most cases is the responsibility of the nonpathogenic species Entamoeba dispar or Entamoeba moshkovskii [6,11,12].…”

Entamoeba histolytica is a cosmopolitan, parasitic protozoan of human large intestine, which is a causative agent of amoebiasis. Amoebiasis manifests with persistent diarrhea containing mucus or blood, accompanied by abdominal pain, flatulence, nausea and fever. In some cases amoebas may travel through the bloodstream from the intestine to the liver or to other organs, causing multiple abscesses. Amoebiasis is a dangerous, parasitic disease and after malaria the second cause of deaths related to parasitic infections worldwide. The highest rate of infections is observed among people living in or traveling through the tropics. Laboratory diagnosis of amoebiasis is quite difficult, comprising of microscopy and methods of molecular biology. Pathogenic species Entamoeba histolytica has to be differentiated from other nonpathogenic amoebas of the intestine, so called commensals, that very often live in the human large intestine and remain harmless. Other intestinal commensals are Entamoeba dispar and Entamoeba moshkovskii, morphologically the same as pathogenic species Entamoeba histolytica sensu stricto. The differential diagnosis of these three amoebas is possible with detection of their DNA.get sick, and 100 thousand people die because of amoebosis-induced infection dysentery [2].E. histolytica belongs to the cosmopolitan parasites, occurring throughout the globe. Particularly exposed to this parasite are people living and traveling to the tropical and subtropical zones (Asia, Africa, India, Indonesia, Mexico, South America, South Africa). These zones climatic conditions are optimal for the Protozoan cysts, which described the external environment can survive for many days. This fact contributes to the increase in the number of infections slider Entamoeba histolytica amongst people in tropical zones. According to Weinke to high-risk groups who are particularly vulnerable to being infected by E. histolytica include men with a homosexual orientation [3]. Prevalence, it means the incidence of infection is low in Poland and is about 1%, while in tropical countries can claim up to 50%. Most of the amoebiasis cases reported in Poland applies to people returning from a different climate zone and foreigners.The digestive tract may be inhabited by several species of nonpathogenic amoebas in the family Entamoebidae, which include Entamoeba coli, Entamoeba hartmanni, Entamoeba polecki, Endolimax nana,. The aforementioned amoebas are so called commensals of colon, which may settle the intestinal mucosa physiologically not attracting damages. There are only isolated reports in the literature that some commensals may lead to pathogenic actions in the human large intestine. There have been a couple of cases of diarrhea problems caused by infections of Endolimax nana, Entamoeba polecki and I. bűtschlii in immunocompromised patients [6].In 1925, Brumpt suggested that within the family Entamoebidae there are species Entamoeba dispar, which is morphologically Abbreviations E.
