Infection with ovine gammaherpesvirus 2 (OvHV-2) is generally asymptomatic in sheep; however, when it crosses the species barrier, it causes malignant catarrhal fever (MCF) in cattle. In the present study, we developed a real-time PCR assay and a droplet digital PCR assay and use both methods to study an outbreak caused by OvHV-2. Both PCR methods showed high sensitivity and specificity and were able to detect low copy numbers of OvHV-2 in sheep and cattle. The present study describes the first digital PCR quantification of OvHV-2 genome copies in samples collected from sheep and cattle.
