Entamoeba histolytica
hallmark of E. histolytica

identical to E. histolytica (nonpathogenic and noninvasive)
Entamoeba dispar
other terms for E. dispar
moushkouski/bangladeshi
small race of E. histolytica (size is half of E. histolytica)
Entamoeba hartmanni
- up to 8 nuclei
- mature cyst
- most number of nuclei in amoebas
Entamoeba coli
cross eyed cyst
Endolimax nana
dwarf internal slug (trophozoite) sluggish motion
Endolimax nana
uninucleated; contains iodophilic inclusion mass (glycogen)
Iodamoeba butschlii
gingival tissue & tartar; no cyst, only trophozoite; WBC ingestion
Entamoeba gingivalis
parasitized pigs and monkeys, uninucleus, non iodophilic, and its inclusion mass
Entamoeba polecki
cigar shaped
E. histolytica, E. dispar, and E. harmanni
splinter-like or broom stick with pointed
Entamoeba coli
with incubation period of 2-5 days; present with bloody diarrhea and abdominal pain
acute/ symptomatic intestinal amebiasis
patients are considered as cyst passers/carrier; stool is soft to well formed
Chronic/Asymptomatic
tumor like mass if granulomatous tissues
amoeboma
flask shaped trophozoite due to hyaluronidase
amoebic ulcers
most common site for extraintestinal amebiasis
liver
commonly used microscope in the laboratory
brightfield microscope
infective stage of E. histolytica
mature cyst (4 nuclei)
MOT of E. histolytica
