Herpvet :
I wish here in Portugal to have exotic VETS available, but only exists one Dr Rui Patricio (maybe a few more in his team and learnig with him) and he is always busy in National Zoos no time for everything !
Of course all national parks have their own team working inside their instituitions !
But outside on citys, dont even one know treatments for a iguana, but they are all comfortably with cats, dogs, birds and Farm animals pigs rabbits and alike.
So, here if you are in the hobby you have to work on your own solutions and since 1995 with the help of internet, try to do your own research. Its better to know a little of english because if you only research portuguese sites you found nothing about this kind of stuff and many others.
Maybe we can found some in brazilian sites.
