I am not sure if this can help, but my vet, I live in Florida, has told me that the college of veterinary medicine at Auburn University in Alabama is one of the best in the country for small animal health care, but I am not sure about what info they may have for you. I think their site is http://www.vetmed.auburn.edu./index.pl/sac. If that link does not work, you should be able to use a search engine to find it.
