All known virus particles can be placed into one of two general categories: enveloped or non-enveloped. Viruses that fall into the former category are characterized by a lipid membrane derived from the host cell, and one or more nuclecapsid proteins that interact with the viral genome. A virus that infects ...

Hosts: Vincent Racaniello, Alan Dove, and Rich Condit On episode 98 of the podcast This Week in Virology, Vincent, Alan, and Rich review the finding of murine leukemia virus-related sequences in the blood of CFS patients and healthy donors, laboratory inventories for wild poliovirus containment, weaving high-performance viral batteries into ...

The new human retrovirus XMRV, first detected in malignant prostate tissue, was subsequently identified in a high percentage of patients with chronic fatigue syndrome (CFS). The virus was not detected in four independent studies of CFS patients in Europe or the United States. The results of a second American study, ...

This week€™s addition to the virology toolbox was written by Danielle Coulson and Chris Upton Comparing genomes of viral strains can provide very useful insight into evolutionary relationships. Recombination, defined by Posada et al (2001) as the exchange of genetic information between two nucleotide sequences, is quite common in many ...
