Question 6

Livscyklus

Giardia

Smitte via transmission af OCYSTER. Disse kan overleve længe selv i koldt vand.
I tyndtarmen frigives trophozoitterne som multiplecerer sig via binær fission. De kan vedhæfte sig mucosaen via sugeplader (her sker en interferering med dyrets/menneskets væske-electrolyfbalance=> diarre). Transit til colon hvor der sker encystering.
