It's the cysts ... they're not "eggs" they contain 4 pairs of infectious bodies in each one.
It's the long lasting (
oocyst (life cycle page) that are the problem
These have thick walls around them that resist efforts to kill their contents.
It can be a
real problem, that will kill your animals
Here's another flash animation of the
basic life cycle on this page
What you have to do is get rid of the internal infection and somehow get the oocysts killed as well. They live up to a year.
Direct household bleach won't do it.
This is made much more complicated by the discovery of multiple species of these little bastards that
infect wild African chameleons. So if you have some WC animals that either carried or picked up a few new species while being imported or held by an importer's (reused and unclean) holding cage/bins until they're sold.
You could have several species in a single animals intestines
as well as a dozen possible hybrids roaming around and have to deal with.
It's truly a mess.
All you need is for a insect to crawl around and pick up a oocyst,
one that's eaten infected feces or a contaminated water source etc.
Not to mention to have one transferred from an infected animal (via handling) to a clean one.
Personally, I bleached everything, cleaned it all up, wrapped it all up in plastic,
put everything in storage and waited over a year before starting breeding again.
These things devastated me.
