    In my opinion, VHFs are among the scariest of viruses. Also, to the best of my knowledge, the reservoir AND vector for the virus have yet to be found. It just pops out of the jungle every so often, and then disappears back into it, Frightening...

      I'm often surprised at how often tagging a protein with another large protein works, i.e. does not interfere with the function of the tagged protein. Considering how complex the process of viral assembly is, I'm not surprised it would be sensitive to the location of the tag.

      Ha, so again, like an organism. Where a population has a great deal of genetic diversity, there are more traits onto which natural selection can act. The more diverse the HIV is at this given stage means a failure in this case though, as the host dies and cannot transmit the disease. Strange.
  • Casey Finnerty on 10 Sep 12
     
    That's a really cool observation, Sarah! It's really all about transmission. Since HIV is (primarily) sexually transmitted, infection in infants (via transovarial transmission) may be considered a dead end for the virus. Perhaps vertical transmission is an aberrance. If HIV would evolve into a less virulent form, perhaps vertical transmission would become more important. Just sayin'...

    This is an interesting article about the gene products that are up-regulated by a rhinovirus infection of respiratory tract epithelial cells, and how that response is limited with the introduction of a cigarette smoke extract. Experiment carried out in human epithelial tissue culture and gene products measured with PCR and immunoblotting.

    Nice molecular evidence behind the observation that smokers get colds more often, don't you think?

      So I think we can see why some virologists were uncomfortable with keeping the swine barn open at the state fair this year!

    Vaccinations are nice, until an antigenic strain is formed. In which case it's back to the drawing board to create a new one as soon as possible. Influenza is constantly changing in order to thrive. Amazing!

  • “This particular virus has never been detected before,” said Nicholson. “This is unique to the world.”So far, the Missouri men are the only known victims of the new germ, which has been identified as a phlebovirus, part of the Bunyaviridae family of potentially serious bugs. Hantavirus, spread by deer mice, comes from that group. So does the deadly Crimean-Congo hemorrhagic fever.

    This paper describes the fascinating replication cycle of brachoviruses, which integrate their genomes (or portions of their genomes) into both wasp and caterpillar hosts, to benefit the parasitic wasp. In this role, these viruses function as endosymbionts, challenging the traditional view of all viruses as parasites.

    Please read this paper for the course. I don't plan to discuss it much more in the course, but there may be questions on this story on your exam.
