Re: Holly wet tail again - 10 months later!
Giardia is microscopic parasites that form cysts. These cysts cling to the surface of the infected Hamster, or they can float free in the mucous lining and pass from the Hamster when he eliminates (poops). Once passed, the cysts can survive for several months outside the animal if sufficient moisture is present.
I've heard dogs can carry it and contaminated water
In most cases, Hamsters can already have the parasite in their bodies at low numbers, but they don't always show signs, and it doesn't always cause any problems, until stress, contaminated food, illness, or something else lowers the immune system and triggers the parasite to go to work, so to speak.
