Infectivity of fish rhabdoviruses for Drosophila melanogaster.

Two fish rhabdoviruses, spring viraemia of Carp virus (SVC) and Pike fry rhabdovirus (PFR), have been shown to multiply in Drosophila melanogaster. The other two fish rhabdoviruses, viral haemorrhagic septicaemia (VHS) and infectious hematopoietic necrosis (IHN), did not multiply under the conditions used. Only those viruses which multiplied (i. e. SVC, PFR) conferred a CO2 sensitivity on the infected drosophila. No hereditary transmission of the fish viruses was detected.
