coccidia and the nematodes unfortunately is one of the wild cards that can attack pretty much anybody (experienced keepers and beginners).
They are part of the environments. You can definitely try to reduce the risk of having your cham getting infected. But, it does not mean that your chameleon will never get it.
Dr Tom Greek says to me that it's pretty common.
I do not know about chameleon.. but when i was researching the darn thing, i found one website claiming that reptiles are actually born with coccidia in their digestive track. And actually benefit them as long as the cocccidia populations are under control by the reptiles' immune system.
Once the balance is out of whack, coccidia then will start attacking the host.
I am a religious cleaner when it's dealing with sanitary.
Nolvosan, Virosan are constantly used to clean my chameleon cage.
I never let poop stay for more than 5 minutes (my chameleon poop in the morning).
I clean the vines and everything once a week.
And Unfortunately one thing slipped from my guard.
The feeder!
I always keep a good sanitary for my feeder too.
I rear my feeder (silkworm and dubia) and has never had any parasite attack (i sent my chameleon's poop samples to my vet regularly).
But, lately, he has a hunger strike.
I bought crickets at a reptile store. Lo and Behold, the next 2 weeks, he contracted with parasites while i am still being sanitary.
Now, I learn my lesson. Nolvosan is not that effective in cleaning.
So, I am just gonna pour hot water on my chameleon cage every major cleaning (or use a steamer).
as far as parasites infected humans, i would say that it is not that rare.
Isn't there used to be a thread in here that the whole family of a chameleon owner get a case of round worm?
So, basically, you just need to practice strict hygiene.
Ever since Dave advise me to wear gloves, I have always wear nitrile gloves everytime I need to make contact with my chameleon.
I kinda glad i did now.. knowing that my cham has developed a mild case of Coccidia and nematodes. sigh
