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 viruses. Because recombination accounts for …

How XMRV, the new human retrovirus associated with prostate cancer and chronic fatigue syndrome, might be transmitted among humans is unknown. The finding that the virus can be detected in prostate cancer cells, and in prostatic secretions of men with prostate cancer suggests that it could be sexually transmitted. To address this question, the presence …
