Virus taxonomy update Taxonomic decisions ratified at the Plenary Meeting of the ICTV at the 9th International Congress of Virology held in Glasgow on the lOth August 1993 The International Committee on Taxonomy of Viruses (ICTV) was founded at the International Congress of Microbiology in Moscow in 1966. Subsequently the ICTV became permanently associated with the Virology Division of the International Union of Microbiological Societies (IUMS) when it was formally established at the 1st International Congress of Virology held in Helsinki in 1968. In the years since then the ICTV has endeavoured to develop a universally acceptable system of virus taxonomy. Today, the ICTV operates through an Executive Committee with seven Sub-committees and 45 Study Groups, involving the participation of more than 376 virologists representing all fields of virology and drawn from many nationalities. The Executive Committee meets regularly between Virology Congresses and prepares taxonomic proposals for ratification at the Plenary Session which is held triennially during the course of the International Congress and which involved the entire membership of the ICTV. Sixty-one proposals were received from Study Groups since the last Virology Congress and fifty-five were presented for final consideration at the 9th International Congress of Virology in Glasgow. Cumulatively, these proposals bring the univeral system for virus taxonomy to one Order, 50 Families, 9 sub-families, t26 Genera, 23 floating Genera and 2 Subgenera. The 6th Report of the ICTV which is scheduled to be published by Springer-Verlag in early 1994 will include all these recent taxonomic changes and present the current taxonomy of viruses in a revised and expanded format. The taxonomic proposals ratified by the Plenary Meeting of the ICTV at the 9th International Congress of Virology in Glasgow are the following: Bacterial viruses
The Chlamydia phages 1. To establish a new genus within the family Microviridae 2. To name the new genus Chlamydiamicrovirus 3. To designate Chlamydia phage Chp 1 as type virus of the genus
The Mac-1 type phages 1. To establish a new genus within the family Microviridae 2. To name the genus containing Mac-1 and related phages BdeIlomierovirus 3. To establish Mac-1 as the type species of the genus
