Amoeba

Front 1

what are the changes the E.Hystolitica undergoes under unfavourable conditions?

Back 1

trophozoite,precyst and cyst

Front 2

life cycle of E.hystolitica

Back 2

stomach, small intestine and large intestine by binary fission

Front 3

state the kinds of amoebiasis

Back 3

• intestinal amoebiasis
• extraintestinal amoebiasis example brain,liver, lung abcess. the most common is hepatic amoebiasis followed by pulmonary amoebiasis after the eruption of the liver abcess through the diaphragm.

Front 4

mode of transmission of E.hystolitica

Back 4

• orogenital
• anogenital
• contaminated food and water

Front 5

give the cyst and the trophozoite stages?

Back 5

• pathogenic stage; trophozoite with asexual reproduction
• diagnostic stage; trophozoite and cyst
• infective stage; cyst

Front 6

the basic process of invasion of intestinal wall by trophozoite

Back 6

• contact with mucosa
• secret proteolytic enzymes to hydrolyze the tissue
• gain access to the tissue
• release enterotoxin and cytotoxinto cause inflammation and lesion inflammation

Front 7

treatment of E.hystolitica

Back 7

Metronidazole and Paromomycin

Front 8

the shallow necrosis by E.hystolitica resembles

Back 8

typical flask-like primary ulcers. because the invasion stops at the muscular mucosa. old lesions, trophozoites with bacteria may invade muscular mucosa

Front 9

the symptoms of luminal amoebiasis

Back 9

gas, intermitent constipation,stomache ache, stomach crampling.

Front 10

portion of the specimen chosen for the examination

Back 10

feces

for formed stools, this may be anypart of the feces but should include a portion of any adherent mucus.

for unformed stools, the mucus or fecal material is more likely to contain E.hystolitica than is liquid.

examination of aspirates

Front 11

other diagnosis methods

Back 11

• culture
• serodiagnosis
• immunological diagnosis
• X-ray
