Key result
Direct multiplex rRT-PCR assay achieves 100% concordance with standard methods for ASF and CSF detection.
Why the study?
African swine fever and classical swine fever are clinically indistinguishable contagious swine diseases, creating a need for reliable test methods for accurate diagnosis and differentiation.
Does a direct multiplex rRT-PCR assay using crude tissue samples provide accurate differential diagnosis of African Swine Fever and Classical Swine Fever compared to standard molecular diagnostic methods in infected pigs and wild boars?
Does a direct multiplex rRT-PCR assay using crude tissue samples provide accurate differential diagnosis of African Swine Fever and Classical Swine Fever compared to standard molecular diagnostic methods in infected pigs and wild boars?
A newly established direct multiplex rRT-PCR assay offers a practical, quick, and reliable technique for the simultaneous differential diagnosis of African Swine Fever and Classical Swine Fever using crude tissue samples.

May facilitate field differentiation of ASF and CSF; leaves open prospective validation before routine adoption.
Nishi et al. (2022) studied African swine fever (ASF) and classical swine fever (CSF). Direct multiplex real-time reverse-transcription polymerase chain reaction (rRT-PCR) assay vs. Standard molecular diagnostic methods was evaluated on Sensitivity and specificity for ASFV and CSFV detection. A newly established direct multiplex rRT-PCR assay for ASF and CSF showed 94.4% sensitivity and up to 97.9% specificity in serum, and 100% concordance with standard methods in crude tissue samples.
