A primary study of the vertical transmission of a kind of spherovirus in Penaeus chinensis
Abstract: With electron microscope, a kind of spherovirus was observed in plasma of penaeid shrimp Puns Chinensis at different stages, such as eggs, larvae and juvenile shrimps. The artificial infection experiment verified that. the spheroviral particle has infectivity. The offsprings coming from carrying virus parental shrimp were infected generally in the separated breeding condition. A kind of spherovirus - like particle was found out in just spawned eggs. The result showed that the spherovirus probablly can be transmitted vertically.
