Answer to Question #309221 in English for Mes

Question

1. What is stool analysis or fecalysis?

2. Write one paragraph about your health teaching to a patient with amoebiasis.

3. Your explanation on what clinical specimen is needed correct diagnosis of this disease.

Answer 1

1) A fecalysis is a series of tests done on a stool (feces) sample to help diagnose certain conditions affecting the digestive tract.

2) Treatment includes medication to kill the parasite and drinking plenty of fluids to prevent a lack of fluid in the body (dehydration). If you develop diarrhoea after travelling abroad to places where E. histolytica is common, you should see your doctor so that amoebiasis or other infections can be excluded. Because amoebas may contaminate food and water, you can help prevent the illness by being careful about what you eat and drink, especially in developing countries. In those areas, a good rule regarding food is to cook it, boil it, peel it, or forget it.

3) The detection of Entamoeba histolytica, the causative agent of amebiasis, is an important goal of the clinical microbiology laboratory. To assess the scope of E. histolytica infection, it is necessary to utilize accurate diagnostic tools. As more is discovered about the molecular and cell biology of E. histolytica, there is great potential for further understanding the pathogenesis of amebiasis. 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. 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. The detection of amebic markers in serum in patients with amebic colitis and liver abscess appears promising but is still only a research tool. On the other hand, stool antigen detection tests offer a practical, sensitive, and specific way for the clinical laboratory to detect intestinal E. histolytica. 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.
