Development of a "Rapid-Crypto Colorimetric LAMP Test" to Detect Cryptosporidiosis in Feces of Newborns Calves.

According to the results, the analytical sensitivity of the "Rapid-Crypto Colorimetric LAMP test" was found as 1 copy plasmid/reaction. When the results were compared with the Real-Time PCR test, the sensitivity of the "Rapid-Crypto Colorimetric LAMP test" was 100% and the specificity was 97.4%. The test did not cross-react with other parasites and bacteria.   CONCLUSION: The "Rapid-Crypto Colorimetric LAMP test" developed in this study provides an advantage in the diagnosis of Cryptosporidium spp. in calf stool samples since it can be applied in basic laboratories or in the field, does not require experienced personnel, and has high sensitivity. Moreover, diagnosis can be made with the naked eye without using any device.
