He writes about viruses at <a href=”http://www.virology.ws” target=”_blank”>virology blog</a>.
  • Subacute Sclerosing Panencephalitis (SSPE) is a rare but almost always fatal sequela of measles virus infection. About 8 years after viral infection, progressive deterioration of neurological function occurs, a vegetative state is entered and death is the outcome. Papua New Guinea has the highest global incidence of SSPE, due to inadequate immunization campaigns.
  • Virons are not the stuff of which fossils are made. But there is an unexpected wealth of non-retroviral virus sequences embedded in the genome sequence databases, a virtual equivalent of the Burgess Shale, ripe for excavation by eager paleovirologists.
  • Mitochondria are of bacterial origin, but the RNA polymerase that transcribes their genome is not. Neither does the enzyme resemble cytosolic eukaryotic polymerases. It is homologous to polymerases of bacteriophages, specifically T3 and T7.

I’ll be back next Friday with more selections.
