Abstract
Bovine alphaherpesvirus 2 (BoHV-2) is the etiologic agent of bovine mammillitis (BM) and pseudo-lumpy skin disease. BM is also important because its clinical presentation can be confused with foot-and-mouth disease (FMD), making it necessary to establish differential diagnoses and perform additional laboratory tests. The objective of this work was to use a validated real-time PCR assay to test for the presence of BoHV-2 in samples from cattle and buffalo with suspected vesicular disease in Brazil. The method could detect the virus at a concentration of 0.5 fg/μL and had 99.4% amplification efficiency, a repeatability error of only 4.1%, and good reproducibility with other reagents. No evidence of BoHV-2 causing vesicular disease in cattle and buffalo was found in this work. This study was able to validate a new methodology for detection of BoHV-2 and evaluate its usefulness for investigating outbreaks of vesicular disease Brazil. The importance of BoHV-2 in cases involving other clinical signs should still be studied using the qPCR developed in this work.
