My cat has been having chronic diarrhea for about two months now and the vet just got his stool sample report back from the lab and everything was negative the only thing that they didn't test for was Crypto? I was wondering if anybody knew what this was and if it is deadly in cats? Also can it be spread to humans? He is going on medicine for it just in case he has it since he wasn't tested for it.

    Cryptosporidiosis is a diarrheal disease caused by microscopic parasites of the genus Cryptosporidium. Once an animal or person is infected, the parasite lives in the intestine and passes in the stool. The parasite is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it very resistant to chlorine- based disinfectants. Both the disease and the parasite are commonly known as "crypto."

    During the past two decades, crypto has become recognized as one of the most common causes of waterborne disease within humans in the United States. The parasite may be found in drinking water and recreational water in every region of the United States and throughout the world.

    How is cryptosporidiosis spread?

    Cryptosporidium lives in the intestine of infected humans or animals. Millions of crypto germs can be released in a bowel movement from an infected human or animal. Consequently, Cryptosporidium is found in soil, food, water, or surfaces that have been contaminated with infected human or animal feces. If a person swallows the parasite they become infected. You cannot become infected through contact with blood. The parasite can be spread by

    Accidentally putting something into your mouth or swallowing something that has come into contact with feces of a person or animal infected with Cryptosporidium.

    Swallowing recreational water contaminated with Cryptosporidium (Recreational water includes water in swimming pools, hot tubs, jacuzzis, fountains, lakes, rivers, springs, ponds, or streams that can be contaminated with sewage or feces from humans or animals.) Note: Cryptosporidium can survive for days in swimming pools with adequate chlorine levels.

    Eating uncooked food contaminated with Cryptosporidium. Thoroughly wash with clean, safe water all vegetables and fruits you plan to eat raw. See below for information on making water safe.

    Accidentally swallowing Cryptosporidium picked up from surfaces (such as bathroom fixtures, changing tables, diaper pails, or toys) contaminated with feces from an infected person.

    There is currently no drug that can cure cryptosporidiosis. People and animals with competent immune systems will recover on their own and appear to develop some immunity to subsequent infections. Anti-diarrheal medicines may ease some of the symptoms. Anyone with diarrhea should drink plenty of fluids to prevent dehydration.

    Cryptosporidia affects the cells of the respiratory and intestinal tracts causing symptoms such as severe diarrhea, nasal discharge, sinusitis, coughing, weight loss and a poor appetite. An effective treatment is currently not available. Again, reducing fecal contamination is necessary to prevent infection with the protozoans.

    Most cats with actual cryptosporidial illness will be FeLV positive or otherwise weakened.

    Diagnosis is made by fecal analysis by sugar flotation (oocysts are acid- fast positive), fecal antigen detection tests, or fluorescent antibody tests.
