ok here goes, i did some research and if you read the info about crypto here is what you find.......
"It lives on (or just under) the surface of the cells lining the small intestine, reproduces asexually, and oocysts are passed in the feces
Crypto lives in the intestine of infected humans, birds, fish reptile and other animals. Millions of Crypto can be released in a single bowel movement from an infected specimen. Infections occur after oral consumption of the parasite. Crypto may be found in soil, food, water, or surfaces that have been contaminated with the feces from infected humans or animals. Crypto is not spread by contact with blood.
In most patients infected with Cryptosporidium the infection causes ashort term, mild diarrhea. Since such symptoms are associated with a number of ailments, infected individuals may not seek medical treatment, and the infection may subside on its own. Thus, it is difficult to say how many Crypto infections occur. On the other hand, individuals with with compromised immune systems can develop pronounced, chronic diarrhea; that may go on for weeks or months. Needless to say, such an infection, if not fatal unto itself, can exacerbate other opportunistic infections common in immunocompromised hosts.
In snakes and other reptiles, the most striking clinical manifestation in chronic infections is swelling of the stomach. "

thus i guess since its intestinal this is where the infamous black blob comes from
, sounds like swelling of the abdomen is common but it should not solely used to diagnose crypto.... only a qualified vet can do that through either necropsy or fecal smears ..
