Abstract
Myxoma virus (MYXV) is a double-stranded DNA-containing virus of the family Poxviridae, genus Leporipoxvirus. MYXV is an important model virus for evolutionary and immunological research and a promising oncolytic. In this study, we sequenced and analyzed two complete genomes of MYXV virus vaccine strains B-82 and Rabbivac-B, which are widely used for vaccine production in Russia. Here, we first show that MYXV vaccine strains B-82 and Rabbivac-B share a common origin with the American recombinant MYXV MAV vaccine strain. In addition, our data suggest that the MYXV B-82 and Rabbivac-B strains contain a number of genes at the 5' and 3' ends that are identical to the virulent MYXV Lausanne strain. Several unique genetic signatures were identified in the M013L, M017L, M023, and M121R genes, helping to achieve high genetic resolution between vaccine strains. Overall, these findings highlight the evolutionary flexibility of certain genes in the MYXV genome and provide insights into the molecular epidemiology of the virus and subsequent vaccine development.
期刊介绍：
Viruses are convenient models for the elucidation of life processes. The study of viruses is again on the cutting edge of biological sciences: systems biology, genomics, proteomics, metagenomics, using the newest most powerful tools.
Huge amounts of new details on virus interactions with the cell, other pathogens and the hosts – animal (including human), insect, fungal, plant, bacterial, and archaeal - and their role in infection and disease are forthcoming in perplexing details requiring analysis and comments.
Virus Genes is dedicated to the publication of studies on the structure and function of viruses and their genes, the molecular and systems interactions with the host and all applications derived thereof, providing a forum for the analysis of data and discussion of its implications, and the development of new hypotheses.
