Establishment of a variant type of turkey herpesvirus which releases cell-free virus into the culture medium in large quantities

Abstract
A variant turkey herpesvirus (HVT/VT) which releases 105.0 plaqueforming units per 0.1 ml of cell-free virus into the culture medium was established from the prototype HVT FC 126 strain (HVT/WT). Many enveloped and naked virions of HVT/VT but only naked virions of HVT/WT were found in the culture medium. By theHindIII restriction cleavage patterns, the HVT/VT DNAs were almost identical to those of HVT/WT. The HVT/VT was replication-defective in chickens.
