Preface to the Third Edition

Since 1997, our knowledge of virology has increased rapidly, and many hitherto unrecognized viruses have emerged either as causes of disease, or from the application of new technologies for virus discovery. In addition, the sterling work of the ICTV since their Sixth Report in 1995 (Murphy et al, 1995) culminated in the Seventh Report published in 2000 (van Regenmortel et al, 2000) in which the majority of vertebrate virus families, genera and species have been reclassified and renamed on the basis of new information, particularly that obtained from nucleotide sequence analysis. These developments are now reflected in this third edition, which is completely revised and rewritten, and follows the new rule for naming virus species as set out in the Seventh Report. All species taxa are now italicized and have the first letter of the word capitalized. As before, I have attempted to include the names and descriptions of all known viruses affecting vertebrates, from humans to fish. Viruses which only infect bacteria, fungi, invertebrates or plants are outside the scope of this Dictionary. In addition to virus names, most of the terms used in virology, as found in the literature on the subject, are also defined. Each virus name entry begins with the taxonomic status, where possible giving the genus to which the virus belongs. As many virus names have changed with the publication of the Seventh Report, cross-references and synonyms are provided liberally to assist the reader. I have also provided many citations, which have been selected so as to provide easy entry into the literature. Space constraints made it impossible to cite many key papers in the field, and omission of a relevant citation should not be taken to mean that it was not considered in writing the entry. Generally, I have chosen to cite useful reviews of papers which include full discussion of the literature of their subject, but occasionally publications are included because of their particular historical significance. Following publication of the second edition, I received useful comments and criticism from several expert virol-ogists, and these have all been incorporated into this third edition. In addition to all my many friends and colleagues in virology, I particularly wish to thank Emilio Battaglia, Robin Buckland, Ulrich Desselberger, Luis Enjuanes, Jon Gentsch, Akira Ishihama, Svetlana Marennokova, Etienne Thiry and Kazuya Yamanouchi for their substantive contributions. As before, I take full responsibility for the contents of this Dictionary, but there are many areas in which I am not an expert, so I invite readers to send me a note of any errors or omissions that they find. I would be grateful to receive suggestions by letter, fax (+404 728 0032) or e-mail ([email protected]), and I will include them in a subsequent edition. Finally I am deeply indebted to my wife Penny for the enormous effort and dedication she has applied to editing this new edition.
