Interpretive Summary:

Technical Abstract: A fluorogenic-probe hydrolysis (TaqMan)-reverse transcriptase PCR for classical swine fever virus (CSFV) was evaluated for diagnostic sensitivity and specificity using clinical samples obtained from the Dominican Republic where the disease is enzootic. The test, using nasal swab samples taken from both symptomatic and asymptomatic animals, exceeded the diagnostic sensitivity of virus isolation (100% vs 72.4%, respectively) with little loss of specificity (98.9% vs 100%, respectively). At the herd level, 3 out of 4 infected farms were detected by virus isolation, while the CSF real time RT-PCR assay identified all four infected premises. This simple and accurate test permits rapid detection of CSFV in affected herds.
