Quantitative analysis of C variabilis virus detects 'distinct species'
Sep 17 2010
The researchers from Ritsumeikan University used pulsed-field gel electrophoresis to study different viruses found in the lake.
Among them was CvV-BW1, a designation given to the virus by the scientists, who selected it for further characterisation.
Their quantitative analysis revealed a linear DNA genome measuring 370 kb, while the virus was seen to form small plaques in testing.
Its properties classify the virus in clade B of a phylogenetic tree constructed for the CvV virus's most resistant H group of strains.
By contrast, all previous strains that have been identified fell into clade A, leading the researchers to conclude that CvV-BW1 represents a distinct species of the virus.
Their findings are published in Virology Journal, an open-access periodical which aims to create an alternative mode of virology communication to the traditional processes used.
