The need to re-formulate the influenza virus vaccine in response to viral antigenic drift and shift makes for complex logistics of vaccine production and administration. Surveillance programs must be conducted each year to identify strains that are likely to predominate and cause disease. Wouldn€™t it be simpler if a single vaccine could be developed that …
John Coffin, Professor of Genetics and Molecular Microbiology at Tufts University, studies the molecular biology and evolution of retroviruses. He wrote a commentary (A new virus for old diseases?) that accompanied the publication by Lombardi and colleagues of the finding of the new retrovirus XMRV in patients with chronic fatigue syndrome, and has spoken widely …
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 an archaeal host may constitute …
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, whose publication was blocked for …
PMRV joins XMRV as possible etiologic agent of chronic fatigue syndrome Read More »
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 …
The World Health Organization has declared the end of the pandemic caused by H1N1 influenza virus. According to Director-General Margaret Chan, The world is no longer in phase 6 of influenza pandemic alert. We are now moving into the post-pandemic period. The new H1N1 virus has largely run its course. As we enter the post-pandemic …
