While there are currently no accepted treatment methods to control livestock infection by these pathogens, many practices can be implemented to help prevent this occurence. Giardia organisms form a resistant cyst that is excreted by the host in its waste. Infections are acquired by ingesting cysts in food or water, or by personal contact with an infected person. Ingesting Giardia may result in Giardiasis, a gastrointestinal illness. High risk groups include the young, elderly, and individuals with immuno-compromised systems.
Prescription medication is available to eliminate the parasite from one's intestinal tract.
Cryptosporidium Cryptosporidium parvum is a protozoan, single-celled parasite, that is carried by animals and people. This protozoan forms an oocyst that is excreted in feces of infected animals and humans. Infections are acquired by ingesting oocysts in food or water, or personal contact with an infected individual. Ingesting Cryptosporidium may result in Cryptosporidiosis, a gastrointestinal illness. There is no drug that can be used to cure Cryptosporidiosis.
