commensals	- E. dispar, - E. moshkovskii, - E. hartmanni, - E. coli, - Endolimax nana, - Iodamoeba butschlii.
an intestinal ameba of pigs and monkeys that has been occasionally detected in humans	Entamoeba polecki
is a probable cause of diarrhea.	Entamoeba polecki
is currently classified within the subphylum Sarcodina, superclass Rhizopoda, class Lobosea, order Amoebida, family Entamoebidae, and genus Entamoeba.	Entamoeba histolytica
previously known as the Laredo strain	E. moshkovskii
The three said species are morphologically identical and of the same size	E. histolytica, E. dispar, and E. moshkovskii
formerly referred to as “small Race” of E. histolytica	Entamoeba hartmanni
is a pseudopod forming non-flagellated protozoan parasite	Entamoeba histolytica
only member of the family to cause colitis and liver abscess.	Entamoeba histolytica , E. dispar, E. moshkovskii, E. hartmanni, E. polecki, E. coli, and E. gingivalis)
The life cycle of E. histolytica consists of two stages:	- infective cyst - invasive trophozoite form.
No host other than humans is implicated in the life cycle, although natural infection of primates has been reported.	Entamoeba histolytica
E. histolytica trophozoites multiply by?	binary fission
They encyst producing uninucleate cysts, which then undergo two successive nuclear divisions to form the characteristic quadrinucleate cysts	E. histolytica
lack of organelles that morphologically resemble mitochondria.	E. histolytica
amebic killing of target cultivated mammalian cells	In vitro
is the most common extra-intestinal form of amebiasis.	Amebic liver abscess (ALA)
The cardinal manifestations of ALA are fever and right upper quadrant (RUQ) pain.	true
Activated ? kill E. histolytica	T-cells
May be epidemic	Bacillary Dysentery
Acute onset	Bacillary Dysentery
Prodromal fever and MALAISE common	Bacillary Dysentery
Vomiting common	Bacillary Dysentery
Patient prostrate	Bacillary Dysentery
Watery, bloody diarrhea	Bacillary Dysentery
Odorless stool	Bacillary Dysentery
Stool microscopy: numerous bacilli, pus cells,	Bacillary Dysentery
macrophages, red cells, no Charcot-Leyden crystals	Bacillary Dysentery
Abdominal cramps common and severe	Bacillary Dysentery
Tenesmus common	Bacillary Dysentery
Natural history: spontaneous recovery in a few days, weeks or more; no relapse	Bacillary Dysentery
Seldom epidemic	Amebic Dysentery
Gradual onset	Amebic Dysentery
No prodromal features	Amebic Dysentery
No vomiting	Amebic Dysentery
Patient usually ambulant	Amebic Dysentery
Bloody diarrhea	Amebic Dysentery
Fishy odor stool	Amebic Dysentery
Stool microscopy: few bacilli, red cells, trophozoites with ingested red blood cells, Charcot-Leyden crystals	Amebic Dysentery
Mild abdominal cramps	Amebic Dysentery
Tenesmus uncommon	Amebic Dysentery
Natural history: lasts for weeks; dysentery returns after remission; infection persists for years	Amebic Dysentery
FECT	Formalin Ether/Ethyl Acetate Concentration Test
MIFC	Merthiolate Iodine Formalin Concentration Test
ELISA	enzyme-linked immunosorbent assay
are the major reservoirs of infection with E. histolytica.	Humans
The genus ? has a spherical nucleus with a distinct nuclear membrane lined with chromatin granules and a small karyosomefound near the center of the nucleus. Trophozoites usually have only one nucleus.	Entamoeba
The genus ? has a vesicular nucleus with a relatively large, irregularly-shaped karyosome anchored to the nucleus by achromatic fibrils	Endolimax
The genus ? is characterized by a large, chromatin-rich karyosome surrounded by a layer of achromatic globules and anchored to the nuclear membrane by achromatic fibrils.	Iodamoeba
which has no cyst stage	Entamoeba gingivalis
is morphologically similar to E. histolytica, but their DNA and ribosomal RNA are different.	Entamoeba dispar
isolates, although first detected in sewage, have been reported in some areas, such as North America, Italy, South Africa, Bangladesh, India, Iran, and Australia.	Entamoeba moshkovskii
is cosmopolitan in distribution, and is considerably more common than other human amebae.	Entamoeba coli
is a parasite found in the intestines of pigs and monkeys.	Entamoeba polecki
which is found in apes and monkeys, is morphologically identical to E. polecki.	Entamoeba chattoni,
can be found in the mouth.	Entamoeba gingivalis
lives on the surface of gum and teeth, in gum pockets, and sometimes in the tonsillar crypts.	Entamoeba gingivalis
occurs with the same frequency as Entamoeba coli.	Endolimax nana
No treatment is necessary because these amebae do not cause disease.	Iodamoeba bütschlii cyst
is a ubiquitous, free-living ameba that is the etiologic agent of Acanthamoeba keratitis (AK) and granulomatous amebic encephalitis (GAE)	Acanthamoeba spp.
is characterized by an active trophozoite stage with characteristic prominent “thorn-like” appendages (acanthopodia)	Acanthamoeba
Acanthamoeba has only two stages, ??, in its life cycle.	cysts and trophozoites
(AK)	Acanthamoeba keratitis
(GAE)	granulomatous amebic encephalitis
(AIDS)	acquired immune deficiency syndrome
is diagnosed by epithelial biopsy or corneal scrapings for recoverable ameba with characteristic staining patterns on histologic analysis.	Acanthamoeba keratitis
. Known species that have caused AK include	A. castellani, A. culbertsoni, A. hutchetti, A. polyphaga, and A. rhysoides.
are free-living protozoans with two vegetative forms: an ameba (trophozoite form), and a flagellate (swimming form).	Naegleria spp.
(trophozoite form)	an ameba
(swimming form).	a flagellate
There are two forms of trophozoites of Naegleria fowleri: ??	ameboid and ameboflagellate
Only Naegleria fowleri has been reported to consistently cause disease in humans, although some non-fowleri species may cause opportunistic infections	true
(CSF)	cerebrospinal fluid
is the causative agent of a rare but rapidly destructive and fatal meningoencephalitis termed primary amebic meningoencephalitis (PAM).	N. fowleri
