Parasitology comparison:
Size:
🫐 Cysticercus cellulose (bladder worm) -> 1-2cm
👑Hydatid cyst -> 1-10cm
✈️Rhabditiform larva -> 1/4 - 1/2 mm

Shape:
🫐 Cysticercus cellulose ->oval
👑Hydatid cyst -> spherical
✈️Rhabditiform larva -> worm like rhabditiform oesophagus with blunt tail

Special features external:
🫐 Cysticercus cellulose -> Scolex (invaginated, 4 suckers, 2 hooks), germinal layer
👑Hydatid cyst -> outer fibrous capsule, middle non cellular laminated layer, inner germinal layer (produce protoscolices & brood capsule)

Special features internal:
🫐 Cysticercus cellulose -> fluid, fibrous tissue
👑Hydatid cyst ->
1. Hydatid fluid (colorless, highly antigenic)
2. Hydatid sand (free brood capsule & protoscolices in Hydatid fluid)
3. Daughter cyst (free cyst in Hydatid fluid or attached to the germinal layer or arising outside the cyst wall

⬛️Toxoplasma
1-Oocyst:- oval ,8-10µ containing 2 sporocysts (4 sporozoites)
2-Tachyzoite:- crescent or oval in shape ,3-7µ, with one end pointed and the other rounded and acentral n.
3-Pseudocyst:- infected cell containing many rapidly Multiplying tachyzoites (found in brain , liver,lung etc in acute stage)
4- True cyst (Tissue cyst):- spherical ,5-50µ , contains numerous slowly Multiplying bradyzound . it is found
in brain and muscles in Chronic stage.
