Development and validation of three Capripoxvirus real-time PCRs for parallel testing.

摘要

Capripoxviruses have the potential to cause outbreaks with a severe socio-economic impact. The latter, combined with an altered virus dissemination pattern, warrants its status as an important emerging disease. Disease control or eradication programmes can only be applied successfully if the necessary diagnostic tools are available allowing clear and unequivocal identification of the pathogen. Real-time PCR combines high sensitivity/specificity with a reduced analysis time and is thus a proven useful tool for identification of many pathogens, including Capripoxviruses. In order for a real-time PCR to be used in a diagnostic capacity, the different analytical and diagnostic parameters need to be evaluated to assure data quality. The implementation of parallel testing using multiple real-time PCRs with similar characteristics can improve further Capripoxvirus diagnosis. It was therefore the purpose of this study to develop a triplet real-time PCR panel with similar high sensitivity/specificity and provide sufficient validation data regarding the performance characteristics that the panel can be used in parallel, depending on the purpose and local situation.
