Classification of viruses is defined by host preference, viral morphology, genome type and auxiliary structures such as tails or envelopes. Viral particles outside a host cell (so called virions) are inert entities with a genome surrounded by a protective coat. Viruses that attack bacteria were named âbacteriophages'.The term phage originates from Greek phagein, which translates as âto eat'.MBO J 28, 821â829 (2009); published online 8 April 2009 [PMC free article] [PubMed]. Viruses are minuscule infectious particles composed of a protein coat and a nucleic acid core. They exist in a huge variety of forms and infect practically all living creatures: animals, plants, insects and bacteria.
