number of nucleus for Trophozoite in E.histolytica

A

1

36
Q

what is a chromatin found in the nucleus

A

karyosome

37
Q

a chromatic material that will surround the karyosome or the nuclear membrane is called

A

peripheral chromatin

38
Q

options for peripheral chromatin

A

even and unevr - if even , it will form an perfect circle

39
Q

the presence of __ as inclusions will be the diagnostic for e. HISTOLYTICA

A

INGESTED RBC

40
Q

chromatoid bars of E. histolytica

A

cigar shape - rounded points

41
Q

for the pathogenesis, we call the disease for the amoeba as

A

amoebiasis

42
Q

2 forms of amoebiasis

A

non invasive and invasive

43
Q

a form of amoebiasis that will comprises the asymptomatic carrier state of the host
“asymptomatic cyst passer”

A

non nvasive

44
Q

ameba colony on intestinal mucosa

A

non invasive

45
Q

in invasive form, it has 2 types, what are day?

A

symptomatic intestinal amoebiasis
and asymptomatic extratestinal amoebiasis

46
Q

first stage in symptomatic intestinal amoebiasis is the

A

amoebic colitis

47
Q

during this stage of symptomatic the patient will encounter gastrointestinal gas such as diarrhea

A

amoebic colitis

48
Q

this symptomatic stage - amoebic colitis can progress into

A

amoebic dysentery

49
Q

“bloody diarrhea”

A

amoebic dysentery - stool with pus cells and mucus during the microscopic examination

50
Q

during the 2nd stage of symptomatic invasive amoebiasis, there will be a diagnosis of

A

flask shaped ulcers causing dysentery

51
Q

secondary bacterial infection is in this case

A

amoebic dysentery stage - symptomatic invasive amoebiasis

52
Q

once the trophozoite migrates and penetrated the intestinal mucosa, it will undergo what process or stage?

A

extraintestinal amoebiasis

53
Q

an invasive stage wherein the amoeba will g out of intestine

A

extraintestinal amoebiasis

54
Q

the main site of infection of extraintestinal amoebiasis is the

A

right part of the liver

54
Q

Chocolate-colored ‘pus will indicate

A

amebic liver abscess

54
Q

Treatment for aAsymptomatic amoebic infection

A

Iodoquinol or Paromomycin

54
Q

infection of amoeba on the right part/lobe of the liver is called ALA, what does ALA stands for

A

amebic liver abscess

54
Q

more example of manifestation when examined microscopically is the thickening of wall called

A

ameboma

54
Q

more example of manifestation is the inflammation of the abdominal wall or the perforation of the intestinal wall which is called

A

peritonitis

54
Q

lessions might expand to diaphram affecting the lungs, it will lead to

A

Pulmonary Amoebiasis or amoebic pneumonitis

Rupture of liver abscess through
diaphragm

Entamoeba dispar, entamoeba hartmanni, and Entamoeba moshkovskii

57
Q

if we recover cyst, HOW do we report E. dispar and E. histolytica

A

Report it as Entamoeba

58
Q

Non pathogenic entamoeba histolytica STRAIN

A

Entamoeba dispar

59
Q

based on the stool consistency for E. dispar, if it’s watery, we report

A

trophozoite

60
Q

based on the stool consistency for E. dispar, if it’s formed, we report

A

cyst

61
Q

Entamoeba coli
Trophozoite:
size:
karyosome:
