文摘

The decapod penstyldensovirus (PstDV1) is a widely spread shrimp pathogen that causes high mortalities in the shrimp Penaeus stylirostris, while in P. vannamei, it has been associated with induction of the runt deformity syndrome. Using shrimp post-larvae (PL, stages PL13-PL21) collected from 16 commercial hatcheries from Mexico, and a sensitive PCR protocol for its detection, a survey of the PstDV1 prevalence in larvae was undertaken. A high overall prevalence of PstDV1 (49.5 %) in shrimp PL from the studied hatcheries was found. This study reveals that PstDV1 occurs persistently in PL populations, which may have significant implications for its dispersal.
