Resúmen

In this rapid communication, a novel atypical bluetongue virus (BTV) strain detected in goats in the Piedmont region (north-western Italy) is described. This strain, BTV-Z ITA2017, is most related in Seg-2/VP-2 (83.8% nt/82.7% aa) to strain TOV of BTV-25. Reactive antisera of goats positive by cELISA for BTV antibodies failed to neutralize a chimeric virus expressing the outermost protein of TOV. Infected animals displayed low levels of RNAemia and absence of clinical signs consistent with bluetongue infection, a scenario described in animals infected with atypical BTV strains.
