Genome of invertebrate iridescent virus type 3 (mosquito iridescent virus).
Iridoviruses (IVs) are classified into five genera: Iridovirus and Chloriridovirus, whose members infect invertebrates, and Ranavirus, Lymphocystivirus, and Megalocytivirus, whose members infect vertebrates. Until now, Chloriridovirus was the only IV genus for which a representative and complete genomic sequence was not available. Here, we report the genome sequence and comparative analysis of ...
متن کاملFine Structure of the Iridescent Virus Type I Capsid
The structure of the iridescent virus type I was examined using negative staining technique. After storage for r to z months at 4 °C or treatment with chloroform, the icosahedral capsid breaks up into its structural elementspentagons and triangles, each consisting of 31 and 55 subunits respectively. When such a preparation is centrifuged through a linear sucrose gradient (Io to 4o%), 5 zones ar...
متن کاملAntimalarial activity of human immunodeficiency virus type 1 protease inhibitors.
Aspartic proteases play key roles in the biology of malaria parasites and human immunodeficiency virus type 1 (HIV-1). We tested the activity of seven HIV-1 protease inhibitors against cultured Plasmodium falciparum. All compounds inhibited the development of parasites at pharmacologically relevant concentrations. The most potent compound, lopinavir, was active against parasites (50% inhibitory...
متن کاملThe DNA virus Invertebrate iridescent virus 6 is a target of the Drosophila RNAi machinery.
RNA viruses in insects are targets of an RNA interference (RNAi)-based antiviral immune response, in which viral replication intermediates or viral dsRNA genomes are processed by Dicer-2 (Dcr-2) into viral small interfering RNAs (vsiRNAs). Whether dsDNA virus infections are controlled by the RNAi pathway remains to be determined. Here, we analyzed the role of RNAi in DNA virus infection using D...
متن کاملMalignant progression of laryngeal papilloma associated with human papilloma virus type 6 (HPV-6) DNA.
A case of laryngeal squamous papilloma in the early stages of development showed histological features suggestive of virus infection. Five years later positive evidence of HPV-6 infection was obtained at a time when the lesion had developed into a squamous cell carcinoma. It is concluded that this case represents a complete example of the virus to papilloma to carcinoma sequence, and as far as ...
