You indeed should be a vet. 
Very informative long post, just the way I like it.
I never thought reptiles can have this many problems too. No idea why, I always thought they have stronger immune system due to some of them have regeneration capability.
Mouth rot is such familiar term. It is a pain in fish keeping as well. We had to use antibiotics to treat it.
Is mouth rot limited to cold blood animals only? I have never heard of any humans or other mammal caught mouth rot.
Did the snakes and lizards get the parasites from swallowing parasites infested prey items? I thought their stomach acid would have killed the parasites since they can dissolve prey whole.
Snakes can be bit by their prey and insects? All this time I have seen on TV, they are so successfully on striking their prey with pin point accuracy.
