PROTOZOANS Flashcards
The two regions of cytoplasm:
ECTOPLASM - OUTER REGION
ENDOPLASM - INNER REGION
The two under of PHYLUM SARCOMASTIGOPHORA:
SUBPHYLUM MASTIGOPHORA
SUBPHYLUM SARCODINA
Organelles of locomotion are hyaline foot like extrusions from ectoplasm called PSEUDOPODIA
SUBPHYLUM SARCODINA
Organelles of locomotion are whiplike structures called FLAGELLA
SUBPHYLUM MASTIGOPHORA
Organelles of locomotion are hair like projections - cilia (Neo Balantidium coli)
PHYLUM CILIOPHORA
Polar rings, subpellicular tubules, conoid, rhoptries and micronemes for penetration and invasion of target cells
PHYLUM APICOMPLEXA
The four class
- CLASS RHIZOPODA/SARCODINA - PSEUDOPODS, AMOEBA
- CLASS MASTIGOPHORA/FLAGELLATA - FLAGELLA
- CLASS CILIOPHORA/CILIATA - CILIA
- CLASS SPOROZOA - NO DEFINITE LOCOMOTORY ORGANELLE
No definite locomotory organelle
CLASS SPOROZOA
No cell wall. Outer membrane is called the
PERIPLAST
Characteristic of protozoans:
- ANIMAL - LIKE PROTISTS
- UNICELLULAR ORGANISM
- NO CELL WALL. OUTER MEMBRANE IS CALLED THE PERIPLAST
RHIZOPODA/SARCODINA: AMOEBA
A. TROPHOZOITE
B. CYST
A. TROPHOZOITE
MOTILE STAGE
FEEDING STAGE
FOUND ON DIARRHEIC STAGE
B. CYST
NON MOTILE
NON FEEDING
INFECTIVE STAGE
FOUND ON WELL - FORMED STOOL
All amoeba are commensal (not pathogenic) except
ENTAMOEBA HISTOLYTICA
All amoeba inhabits the colon except
ENTAMOEBA GINGIVALIS
All amoeba with cystic stage except
ENTAMOEBA GINGIVALIS
The only pathogenic amoeba
ENTAMOEBA HISTOLYTICA
What are under or 2 types of ENTAMOEBA HISTOLYTICA:
AMOEBIASIS
EXTRAINTESTINAL AMOEBIASIS
Saang part ng katawan matatagpuan ang EXTRAINTESTINAL AMOEBIASIS
LIVER, LUNG, SPLEEN, BRAIN, ETC.
Flask shaped ulcer of colon, Amebic liver abscess, CNS, renal, genital and cutaneous involvement.
PATHOGENESIS
Suppressor factor …….
VIRULENCE FACTOR
A new species of entamoeba isolated in Japan
ENTAMOEBA MARINA
Smallest amoeba (size of an RBC)
ENDOLIMAX NANA
- Smaller than E. HISTOLYTICA
- With sluggish motility
TROPHOZOITE
Iodamoeba butschlii
A. TROPHOZOITE:
B. CYST:
A. TROPHOZOITE
- With achromatic karyosome kromatin
B. CYST
- Mature cyst has 1 nucleic
- With large iodine staining glycogen vacuole
Intestinal parasites of pigs and monkeys
ENTAMOEBA POLECKI
Resembles entamoeba histolytica cyst, however it has angular pointed….
CYST
Resembles entamoeba coli trophozoite however it has smaller karyosome….
TROPHOZOITE
Morphologically similar to E. Histolytica but DNA and RNA content is different
ENTAMOEBA DISPAR
Also similar to E. Histolytica but smaller in Cyst (5-10 um) and is quadrinucleate …….
ENTAMOEBA HARTMANNI
