Cryptosporidium cuniculus was originally detected in rabbits and it has been identified as a human pathogen. However, the incidence, prevalence, and epidemiology of cryptosporidiosis due to C. cuniculus in rabbits and in human populations are still poorly studied. As the identification of C. cuniculus can be time consuming and expensive using the existing molecular assays, such as nested PCR followed by the sequencing of the amplified fragments, in this study it will be used real-time PCR in order to amplify fragments of the glycoprotein gp60 gene, specific for C. cuniculus Va and Vb subtypes. The real-time PCR will be performed with SYBR Green and two sets of specific primers, and after the reaction, the amplified product will be subjected to a dissociation curve analysis at high resolution (HRM).
