[Ultrastructure, development and nucleic acid of the S virus from the decapod crustacea Macropipus depurator L]. / Ultrastructre, développement et acide nucléique du virus S du crustacé décapode Macropipus depurator L.

The "S" crabe virus recently isolated from Macropipus depurator (Decapoda) has been purified and its nucleic acid has been recognized as a DNA. The visualization of the structure and of several phases of the cycle of the virus permits to situate this virus near the Bunyavirus and Paramyxovirus groups.
