Preface to the Second Edition

This Dictionary is based on an earlier one with KEK Rowson and TAL Rees, that was published in 1981; at that time HIV was unknown, and AIDS had not yet been recognized as a virus disease. The past 15 years have witnessed an enormous increase in our knowledge of viruses and their taxonomic relationships. An attempt has been made in the present volume to include all the names of viruses affecting vertebrate species which have been used in English language papers. In addition, brief descriptions of terms used in virology and relevant terms used in genetics, immunology and molecular biology are included. Those viruses which only infect invertebrates, plants, fungi or bacteria are outside the scope of this Dictionary.

Each virus entry begins with the taxonomic status (usually genus, or if not assigned, subfamily, family, etc). Further information can normally be obtained by consulting the genus or family entries where they exist.

Where possible, I have followed the rules for virus nomenclature contained in 'Virus Taxonomy: Sixth Report of the International Committee on Taxonomy of Viruses (ICTV)', Archives of Virology, Supplement 10, edited by FA Murphy, CM Fauquet, DHL Bishop, SA Ghabrial, AW Jarvis, GP Martelli, MA Mayo and MD Summers; New York: Springer, (1995). In cases where the virus species does not have an approved name, the entry is made under a name which follows the rules of the ICTV Sixth Report. Synonyms refer to the main entry under the approved ICTV name.

Entries whose titles consist entirely of figures, e.g. 127 virus, are placed at the front of the Dictionary, otherwise the order is strictly alphabetical. For this purpose, numbers forming only part of a title are disregarded except where they differentiate between otherwise identical names. Chemicals are entered according to the initial letter of the first full syllable of the name, and prefixes such as Greek letters and numbers are ignored. Prefix letters in the names of cell lines are always taken into account.

This Dictionary is not in any way intended to serve the function of a virus textbook but rather as a data source, and many entries include references (usually not more than three) which are intended as a starting point for further reading. Where possible, these are review articles or papers containing a good discussion of the subject. Preference has been given to recent publications rather than the original description, and to papers with a useful list of references. Although the length of each entry reflects to some extent the overall importance of the virus, it is clear that for the majority of the viruses listed, little information is currently available. If this stimulates the reader's curiosity and ultimately leads to further research on virus diseases and their prevention and control, it will have served a useful purpose.

The specialized reader may find errors or omissions in this Dictionary, and I would be grateful to learn of them by letter, fax (+ 404 728 0032) or e-mail ([email protected]), so that they may be corrected in a subsequent edition.

Although numerous persons have provided advice and assistance in preparing this work, I am especially indebted to KEK Rowson for his hard work on the earlier edition, and to Tamie Ando, Tom Barrett, Charlie Calisher, Joe Esposito, Jon Gentsch, Joe Icenogle, Sy Kalter, Fred Murphy, Stuart Nichol, Pat Nuttall, Bernard Roizmann, Chuck Rupprecht and Jim Winton for their expert advice.

Finally, my deepest thanks are due to my wife, Penny, who helped put the Dictionary together on computer and did the bulk of the editorial work. Without her help it would not have seen the light of day.
