This is what the pathologist had to say-- "Clinical diagnosis: Open, neuromuscular disease. Gross: Received in formalin are 10 tissues to 4cm in greatest dimension that are processed in three blocks following appropriate decalcifcation of block #3. Histopathological diagnosis: 1. Myofiber atrophy, necrosis, dysgenesis, and fibrosis, skeletal muscle. 2. No pathologic diagnosis, skin, bone, central nervous system, alimentary tract, kidney, lung, heart, live. Comment: Histologic findings are consistent with some form of muscular dystrophy, and this lesion may have been a congential/hereditary problem. There is no evidence of an infectious process." So it appears Mercutio was doomed from the start. It does make me feel better knowing that I didn't make him sick and that there wasn't anything else I could have done for him. I'm emailing the breeder this info now, since he probably shouldn't breed the snakes that produced Mercutio, at least not together again, though probably not at all.
