virus. Some of the important landmarks and achievements in the field of virology are summarized in Fig. 1.14. It is apparent that much has been discovered about the biology of viruses and about host defenses against them. Yet the more we learn, the more we realize that much is still unknown.

      In the first edition of this textbook (published in 2000), we noted that the most recent (1995) report of the ICTV listed 71 different virus families, which covered most new isolates. We speculated therefore that: “As few new virus families had been identified in recent years, it seems likely that a significant fraction of all existing virus families are now known.” In the intervening years, this prediction has been shattered, not only by the discovery of new families of viruses, including giant viruses with genome sizes that surpass those of some bacteria, but also by results from metagenomic analyses. For example, the fact that a high percentage (93%) of protein-coding sequences in the genomes of the giant Pandoraviruses have no homologs in the current databases was totally unexpected. The unusual morphological features and atypical reproduction process of these viruses were also surprising. In addition, it is mind-boggling to contemplate that of almost 900,000 viral sequences identified in samples of only one type of ecosystem (raw sewage), more than 66% bore no relationship to any viral family in the current database. From these analyses, and similar studies of other ecosystems (i.e., oceans and soil), it has been estimated that only a minor percentage of extant viral diversity has been explored to date. Clearly, the viral universe is far more vast and diverse than suspected only a decade ago, and there is much fertile ground for gaining a deeper understanding of the biology of viruses and their host cells and organisms.

      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.

       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.
