Papers of Special Interest
Boylston AW. 2018. The myth of the milkmaid. N Engl J Med 378:414–415.
A delightful scientific historian’s report on research that debunks the much-cited notion that Edward Jenner was inspired to test the benefits of cowpox by the comments of a milkmaid who claimed to be immune to smallpox because she had had cowpox.
Breitbart M, Salamon P, Andresen B, Mahaffy JM, Segall AM, Mead D, Azam F, Rohwer F. 2002. Genomic analysis of uncultured marine viral communities. Proc Natl Acad Sci U S A 99:14250–14255.
Early use of metagenomic analysis to identify viruses in natural marine environments. One of the first to identify these agents using these methods, and to reveal the enormity in number of previously unknown viruses in these environments.
Crick FHC, Watson JD. 1956. Structure of small viruses. Nature 177:473– 475.
Authors deduce from X-ray crystal analysis of plant virus particles that virus shells (capsids) are composed of a large number of identical protein molecules, of small or moderate size, packed together in a regular manner.
Murray NE, Gann A. 2007. What has phage lambda ever done for us? Curr Biol 17:R305–R312.
The authors describe how study of the bacteriophage lambda has contributed to an understanding of the molecular basis of numerous fundamental biological processes.
Suttle CA. 2007. Marine viruses—major players in the global ecosystem.
Nat Rev Microbiol 5:801–812.
Suttle describes the unappreciated yet enormous contribution that the huge numbers of marine viruses make to the earth’s marine and global ecosystems.

STUDY QUESTIONS
1 What is the definition of a virus?
2 Which is a key property first discovered about viruses that distinguished them from other microorganisms?They were too large to pass through a 0.2-micron filterThey could reproduce only in brothThey made tobacco plants sickThey were small enough to pass through a 0.2-micron filterNone of the above
3 All of us carry many different viruses throughout our daily lives. Why don’t they make us sick?
4 Why do we care that viruses comprise the most biodiversity on the planet?
5 The first viruses were discovered near the end of the 1800s. How was this done?By transmitting a disease to tobacco plants using a cell-free filtrate of diseased leavesPasteur showed that viruses could reproduce in a sterile mediumLeeuwenhoek saw viruses in his microscopeRobert Koch showed that viruses grown in broth could cause diseaseAll of the above
6 Why were the bacteriophage systems so useful for elucidating principles of viral reproduction? What important features of virus-host interactions were discovered from these studies?
7 How are viruses classified?
8 How does the discovery of new viruses today differ from 100 years ago?
9 Which host cell function is essential for the reproduction of all viruses?
10 What is the basis of the Baltimore classification system? How many genome types are sufficient to describe all viral families in this system?
