The parents were survivors from an OsHV-1 mortality outbreak. OsHV-1 DNA was not detected by conventional PCR in the mantle of parents, gametes or 3 day-old larvae. However, viral DNA was detected by real-time PCR in all gametes and larvae samples. These results show that C. angulata that have survived an OsHV-1 mortality outbreak can carry the virus and vertically transmit it to their offspring. (C) 2016 Elsevier Inc.
