Not sure about the gear, the vet said he would need either regurged food, a "fresh" stool sample or a sample of the snakes stomach-content.
Ah, good deal.
Regurged food, or stomach content (taken no later than three days after being fed), would yield better/easier diagnostic results than would a stool sample. Not saying that a stool sample should not be used ... just mentioning what may be better.
However he also said that there are some experimental treatments, but of course there's no cure yet. I told the vet that I gladly donate my sick snakes for experimenting.
BTW
I read that Crypto is very common among leopardgeckos,
Yes, Crypto affects Geckos as well and ... I can see where it may be, or could be, fairly prevalent (due to their, commonly, being kept in groups).
Actually, most all living creatures can become infected with (or carry) Crypto. It is just that different types, of Crypto, affect different animals, reptiles, etc.,.. and humans.
There are multiple types of Cryptosporidium. Any non host specific Crypto just passes through the gastrointestinal tract without any ill affects to the animal/reptile that ingests, or inhales, it. It is only when the type of Crypto is host specific that infection occurs and problems develop.
The two primary types, which infect/affect snakes & lizards, are Cryptosporidium serpentis (snakes) and Cryptosporidium saurophilum (lizards).
C. serpentis is the primary form, of Crypto, that infects snakes ... but it can, also, infect lizards. So, lizards can become infected with either C. saurophilum, or C. serpentis, or both (though it is, commonly, C. saurophilum).
It seems that (though it is, commonly, C. serpentis) snakes can, also, become infected with C. saurophilum ... but on a much lesser scale. IOW It appears to be extremely limited (or more difficult) for snakes to become infected with C. saurophilum than it is for lizards to become infected with C. serpentis.
I have heard of experimental treatments but its efficacy appears to be somewhat limited in that they have not served in eliminating Crypto, from the system, altogether (does not cure).
So far, any successful treatments have only reduced symptoms &/or reduced, or prevented, the shedding of oocysts (which could, possibly, resume at a later time).
From what I understand, even those snakes/reptiles, that are treated, should remain in a quarantine type situation until further study/research.
I would love to hear of any experimental treatments that are even better, or in more advanced stages, than what has been done/found so far. Better yet ... I hope a cure can be found... soon.
but the crypto that leopardgeckos get seem to be curable, Tremper has written an article about it.
I don't know of a cure for Geckos.
Not sure of what Ron Tremper is doing treatment wise (or cure? wise).
Just may have to look up Tremper's article ... &/or any news on what he is doing or has done. It could be interesting to find out.
