Characterization of Triatoma Virus, a Picorna-like Virus Isolated from the Triatomine Bug Triatoma infestans Muscio, O. A. and La Torre, J. L. and Scodeller, E. A.,, 69, 2929-2934 (1988), doi = https://doi.org/10.1099/0022-1317-69-11-2929, publicationName = Microbiology Society, issn = 0022-1317, abstract= Summary Some properties of Triatoma virus (TrV), a picorna-like virus recently isolated from Triatoma infestans, have been studied. Electron microscopic observations of purified viral preparations showed the presence of non-enveloped viral particles 30 nm in diameter. The sedimentation coefficient of virus particles was about 165S and the buoyant density in CsCl was 1.39 g/ml. The viral genome was composed of one single-stranded RNA molecule with an M r of 3 × 106. Three major polypeptides with M r values of 39K, 37K and 33K and a minor one of about 45K were found in the virus particle. TrV particles contain about 35% RNA and 65% protein by weight. These data support the classification of this virus in the family Picornaviridae., language=, type=
