[Thamnophis]

Thanks for explaining, Cyrill.
It's a good thing you keep such strict quarantaine-rules.
I know by experience that this is very neccesary sometimes.
In the Reptile-Zoo where I work we give shelter to all kind of reptiles, also smuggled specimens that are taken away from the smugglers (seized?). This are often wildcaught animals or animals that did not get the right care during long periods. Often they are ill an wak.
We keep a very strict quarantaine-management.
This pays off. Our exhibition-animals do not get the diseases.
