Balantidium coli
Life cycle 
-
- Excystation - single cyst gives rise to single tropozoite
- Transverse Binary fission
First divide macronucleus then macronucleus, food vacuoles and contractile vacuole and form parasite mouth
- Conjugation - parasite mouth joined together and transfer genetic material then separate
-
- Encystation and excrete through feces
Pathogenesis
-
Affect human, recover within 3-4 days even without any treatment
Some cases, intestinal ulcers- it either specific round or irregular shape or pus filled structure
-
Maximum have Nausea,
Vomiting,
Diarrhea or dysentery stools
-

Morphology
Trophozoite
-
-
-
-
Bottom region called cytopharynx, it extend as sac like cavity
-
-
2 nucleus
-
Micronucleus - small round shape , close by macronucleus
-
Food vacuole
-
Parasite take Bacteria, cell debris, fat, RBC cells, these are digest by food vacuole. Excrete through Anal opening (cytopage).
-
-
Cyst
-
Shrink the cilia , both nucleus and contractile vacuole
