Classification

This is a description of a bacterial virus at the isolate level.

ICTVdB Virus Code: 02.066.0.00.118. Virus accession number: 66000118.

Name, Synonyms and Lineage

Synonym(s): Lactobacillus bacteriophage lb539. ICTV approved acronym:

. Acronym(s): lb539. Virus is not assigned to a genus; of the family 02.066. Siphoviridae; of the order 02. Caudovirales.

Virion Properties

Morphology

Phages consist of a head and a tail and are not enveloped. Phage has a head with icosahedral symmetry and a tail with helical (tail) and icosahedral (head) symmetry. The tail is long; is non-contractile; is filamentous.

Nucleic Acid

The genome is not segmented and contains a single molecule of circular double-stranded DNA. The complete genome is about 37000 nucleotides long.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are not reported.

Infection and Replication: Infection involves a noncytocidal productive infectious cycle (temparate phage).

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Bacteria.

Domain Bacteria
Phylum Firmicutes; Class Bacilli; Order Lactobacillales; Family Lactobacillaceae, Genus Lactobacillus.

Host Classification Virus infects Genus Lactobacillus; Species delbrueckii; strain/isolate CRL 539.

Taxonomic Proposals and Changes

At the meeting in Jerusalem, August 1996, it was proposed to create a new taxon. The proposal has been approved at the meeting of the Executive Committee in Strasburg, 1997. The taxon has been designated as Species (in the genus "c2-like viruses").
