At the beginning of this year, our corn snake Tezzeret started regurgitating his meals. I've spent the last several months collaborating with our herp vet and fighting to nurse him through it, with no success. At our appointment with the vet tonight, he was differentially diagnosed with cryptosporidosis. The infection had already progressed to the point that his kidneys were affected, so we made the hard decision to have him euthanized before he lost any more weight or got any weaker.

I know crypto is incredibly contagious. I'm going to bring our other snake, a ball python, in for an initial PCR test since it's likely he's been exposed.

My question is how worried do I need to be about cross-contamination from the corn snake(s) to our collection of lizards (mostly rhac geckos, one skink)? My fiancee and I practice decent hygiene between our animals, but I have to admit it's not impeccable. Though I generally clean lizard items separate from snake items, there's still a decent possibility that lizard dishes and snake dishes have been washed together at the same time.

I'm trying not to freak out here but I'm freaking out a little here. How much freaking out is appropriate in this situation?
