Over 5100 bacterial viruses have been examined in the electron microscope since 1959. About 4950 phages (96%) are tailed and only 186 phages (3.6%), are cubic, filamentous, or pleomorphic. Phages… (More)
This review summarizes the electron microscopical descriptions of prokaryote viruses. Since 1959, nearly 6300 prokaryote viruses have been described morphologically, including 6196 bacterial and 88… (More)
One-hundred-fifteen bacteriophage strains were isolated from alkaline hot springs in Iceland, New Zealand, Russia (Kamchatka), and the U.S.A. The phages belonged to the Myoviridae, Siphoviridae,… (More)
Bacterial viruses have been classified into 13 families and 1 unassigned genus. A new order, Caudovirales, has now been established, comprising the three families of tailed bacterial viruses, based… (More)
Out of 136 new phages, 80 (59%) are classified into 23 species according to morphology and physicochemical properties. Six new species are described and species b4, from a previous classification… (More)
Bacteriophages are listed by morphotypes and host genera. At least 4.007 phages, belonging to 13 virus families, have been described since 1960. About 3,850 phages (96%) are tailed and 154 phages… (More)
The T4-type of bacteriophages is broadly defined on the basis of particle morphology. It occurs in enterobacteria (125 representatives), acinetobacters, aeromonads, pseudomonads, and vibrios (16… (More)
Eight phage species and type viruses are proposed. They belong to theMyoviridae, Siphoviridae, andPodoviridae families of tailed phages and are characterized by a combination of morphological and… (More)
“Phages” include viruses of eubacteria and archaea. At least 5568 phages have been examined in the electron microscope since the introduction of negative staining in 1959. Most virions (96%) are… (More)
A recently proposed polythetic definition of virus species appears easily applicable to bacteriophages. Criteria for classification of tailed phages are evaluated. Morphology, DNA homology, and… (More)
