Host Range and Specificity of the Drosophila C Virus

Host Range and Specificity of the Drosophila C Virus

BACKGROUND The Drosophila C virus (DCV) is a common and well-studied Drosophila pathogen. Although natural infections are known from Drosophila melanogaster and D. simulans, and artificial infections have been reported from several Drosophila species and other insects, it remains unclear to date whether DCV infections also occur naturally in other Drosophila species. METHODS/PRINCIPAL FINDING...

Broadbean wilt virus - identification,host range and distribution in the fars province of iran

Drosophila-host genetic control of susceptibility to Drosophila C virus.

Interactions between Drosophila C virus (DCV) and its natural host, Drosophila melanogaster, were investigated using 15 geographical population samples infected by intraabdominal inoculation. These strains derived from natural populations of D. melanogaster differed in susceptibility to the DCVc. One strain was "partially tolerant". Isofemale lines obtained from one susceptible and one partiall...

Induction of host defence responses by Drosophila C virus.

Insect responses that are specific for virus infection have been investigated using the genetically tractable Drosophila melanogaster. Most studies focus on interactions with Drosophila C virus (DCV), which is a member of the family Dicistroviridae. DCV is a non-enveloped, T=3 icosahedral virus with a positive-sense RNA genome. It was demonstrated recently that several genes controlled by the J...

Host range, host specificity and hypothesized host shift events among viruses of lower vertebrates

The successful replication of a viral agent in a host is a complex process that often leads to a species specificity of the virus and can make interspecies transmission difficult. Despite this difficulty, natural host switch seems to have been frequent among viruses of lower vertebrates, especially fish viruses, since there are several viruses known to be able to infect a wide range of species....
