Diagnosis is by finding the oocysts in a fecal examination or by an antigen detection test. Electrophoretic and immunoblot analysis showed that specific animal antibody response appeared between Day 4 and Day 15 post inoculation. A blue line of any intensity will appear at the Giardia test position if Giardia antigen is present and a red line of any intensity. There are no drugs approved for the treatment of Cryptosporidium canis. Cryptosporidium infection can spread through multiple channels, including animal-to-human, person-to-person, and through water; the parasite is a leading causes of waterborne disease outbreaks linked to recreational water like pools. Correctly diagnosed positive samples included Cryptosporidium parvum genotypes 1 and 2, whereas the single false-negative sample corresponded to a Cryptosporidium meleagridis infection. The sensitivity, specificity, and positive predictive value of the ELISA were 87%, 99%, and 98%, respectively, as determined by examination of 231 fecal specimens by conventional microscopy and by ELISA. The observed sensitivity was 98%, while specificity was 100%; the detection threshold was near 1000 oocysts/ml. Giardia and Cryptosporidium are the most common causes of parasitic gastroenteritis in the United States. • If EIAs are negative, request add-on testing for Ova and Parasites Examination , and submit an additional specimen after five days for O&P examination. About this test. Cryptosporidium is a protozoan parasite that causes an infection called cryptosporidiosis. This Eagle Biosciences Fecal Cryptosporidium Antigen ELISA is a “sandwich” ELISA that is designed, developed and produced for the qualitative measurement of Cryptosporidium parvum antigen in stool specimen. The latter is less sensitive and requires specialized techniques (eg, phase-contrast microscopy, acid-fast staining). Cryptosporidium primarily infects the distal small intestine. ACKNOWLEDGMENTS.
