moshkovskii are nonpathogenic and noninvasive parasites that are identical morphologically to E. histolytica is a pathogen or invasive parasite, whereas E. histolytica infection during a 1-year study ( 81).Į. For example, it was observed that 39% of children from an urban slum in Dhaka, Bangladesh, had a new E. The vast majority of these infections are acquired in the developing world. histolytica causes approximately 50 million cases and 100,000 deaths annually ( 13, 229). The World Health Organization reported that E. This is because amebiasis is presently one of the three most common causes of death from parasitic disease. The detection of Entamoeba histolytica, the causative agent of amebiasis, is an important goal of the clinical microbiology laboratory. All the current tests suffer from the fact that the antigens detected are denatured by fixation of the stool specimen, limiting testing to fresh or frozen samples. On the other hand, stool antigen detection tests offer a practical, sensitive, and specific way for the clinical laboratory to detect intestinal E. The detection of amebic markers in serum in patients with amebic colitis and liver abscess appears promising but is still only a research tool. In all cases, combination of serologic tests with detection of the parasite (by antigen detection or PCR) offers the best approach to diagnosis, while PCR techniques remain impractical in many developing country settings. Molecular biology-based diagnosis may become the technique of choice in the future because establishment of these protozoa in culture is still not a routine clinical laboratory process. histolytica, there is great potential for further understanding the pathogenesis of amebiasis. As more is discovered about the molecular and cell biology of E. histolytica infection, it is necessary to utilize accurate diagnostic tools. As such self-collected specimens from SARS-CoV-2 positive individuals may yield negative results if the specimen was not collected properly.The detection of Entamoeba histolytica, the causative agent of amebiasis, is an important goal of the clinical microbiology laboratory. Specimens that are self-collected will not be tested with an internal control to confirm that the specimen was properly collected.
