Document Summary
14 november 2018: naegleria fowleri, acanthamoeba spp, introduction, entamoeba dispar, entamoeba hartmani, entamoeba coli, entamoeba gingivalis, endolimax nana, iodamoeba butschlii, nonpathogenic protozoa (npp) Flagellates - phylum metamonada: giardia lamblia, trophozoite, cyst, life cycle, pathology, diagnosis, treatment, prevention, trichomonas, general characteristics, trichomonas vaginalis. Study questions: why should we learn about npp"s, oro-fecal contamination, potential infection with pathogens, make correct diagnosis. Troph = 8 microns cyst = 6 microns. Describe the structure of the nucleus and speed of the trophozoite"s movement. Organisms that are normally free-living in soil or water. Enzymes break down brain tissue hemorrhage and necrosis. Acanthamoeba spp: enter hosts via respiratory tract or through the skin (cut as entry) Draw a g. lamblia trophozoite and include the following: Trophozoite: adhesive discs, nuclei, flagella, and median bodies. 2 adhesive discs used to hold onto tissues. 2 median bodies microtubules and formation of adhesive discs. Trypsin stimulate attachment of adhesive discs. Ingested by next host excysts in small intestine.
