Re: C oreganus necropsy
Wow, great job Randy! That was very thorough and most of the tissues look quite clean. I agree that the stomach contents look like a parasitic infection to me. If a large quantity of sand were ingested, you would see clumping of it all through the intestines. If you have access to a microscope, you can look at the stomach contents under it to see if it is sand or worms. But from the rather sesame-seed shape of the contents, I think it's some kind of parasite...that could have killed the snake.
The lesions are probably tumours, which from their location, may very well have been the cause of neurological issues. It is also possible that they are benign fatty tumours. I dont' think you can really tell the difference without cell culturing and testing for cancer-associated proteins.
Anyway, that was an excellent necropsy, and my guess would be that parasitic infection overwhelmed the snake. It's sad, but it's unfortunately common in wild-caught snakes, and can take years to build up to critical load. I'm dealing with two LTC bush vipers that have whipworms and are probably not going to make it. It's heartbreaking. With the information you have from the necropsy, I think you're best to go ahead and treat the remaining snakes with Panacur.
Panacur is sold as a white paste in most tractor and farm supply stores, and even in Walmart. You want to make sure the active ingredient is fenbendazole, if you're buying the generic kind.
The paste is 100mg fenbendazole/1g paste, and 25g are usually in a tube. With that information, you can assume that there are 2500mg in the tube. This can be diluted with Pedialyte, 25mL to a concentration of 100mg/mL. The normal dosage is 50mg/kg for a snake, so you would give 0.5mL for each kg of weight. Use the clear, unflavored Pedialyte if you can find it. This provides some nice electrolytes that the snake will be low on due to parasites as well as the medication. If the snake will feed readily, inject the Panacur mixture into its f/t prey.
