  • Relevance
    Members of the genus Cryptosporidium are parasites of the intestinal tracts of fishes, reptiles, birds, and mammals. It seems that members of this genus do not display a high degree of host specificity, so the number of species in this genus remains a matter of some discussion. Cryptosporidium isolated from humans is now referred to as C. parvum. Cryptosporidium infections have been reported from a variety of wild and domesticated animals. Cryptosporidiosis is now recognized as an important opportunisitic infection, especially in immunocompromised hosts. Cryptosporidium is a small protozoan parasite, measuring about 3-5 µm. It lives on (or just under) the surface of the cells lining the small intestine, reproduces asexually, and oocysts are passed in the feces. Transmission of the infection occurs via the oocysts. Many human infections have been traced to the contamination of drinking water with oocysts from agricultural "run-off" (i.e., drainage from pastures), so it is considered a zoonosis. The most common symptom of cryptosporidiosis is watery diarrhea; other symptoms include stomach cramps or pain, fever, nausea and vomiting. In persons with healthy immune systems, symptoms usually last about 1 to 2 weeks.

Customer reviews and Q&As


Thank you for contacting us. I have some further information regarding ab20787 Cryptosporidium parvum antibody. The antibody will detect intact oocysts. We have not tested this antibody against infectious particles/infected cells. The immunogen used to produce this antibody is intact oocysts. Unfortunately we do not have an ICC image available. The antibody crossreacts with a rod-shaped microorganism found in bovine feces. It was thought that this crossreactivity may have been caused by a contaminant organism that co-purified with the immunogen oocysts, but this microorganism has not been identified. This microorganism is not associated with infected cells. I hope this information helps. Please do not hesitate to contact me should you have additional questions.
