Bacteriophage φCb5
''Bacteriophage φCb5'' is a bacteriophage that infects '' Caulobacter'' bacteria and other caulobacteria. The bacteriophage was discovered in 1970, it belongs to the genus '' Cebevirus'' of the '' Steitzviridae'' family and is the namesake of the genus. The bacteriophage is widely distributed in the soil, freshwater lakes, streams and seawater, places where caulobacteria inhabit and can be sensitive to salinity.

Description The capsid has icosahedral geometries, and T = 3 symmetry. It does not have a viral envelope. The diameter is around 26 nm. The genomes are linear, positive single-stranded RNA, and about 3.4 kb in length. The genome segmentation is monopartite and has 2 or 3 ORFs. Viral replication occurs in the cytoplasm and entry into the bacterial cell occurs by penetration into the pilus. The routes of transmission are by contact.

Bacteriophage
A bacteriophage (), also known informally as a phage (), is a virus that infects and replicates within bacteria. The term is derived . Bacteriophages are composed of proteins that Capsid, encapsulate a DNA or RNA genome, and may have structures that are either simple or elaborate. Their genomes may encode as few as four genes (e.g. Bacteriophage MS2, MS2) and as many as hundreds of genes. Phages replicate within the bacterium following the injection of their genome into its cytoplasm. Bacteriophages are among the most common and diverse entities in the biosphere. Bacteriophages are ubiquitous viruses, found wherever bacteria exist. It is estimated there are more than 1031 bacteriophages on the planet, more than every other organism on Earth, including bacteria, combined. Viruses are the most abundant biological entity in the water column of the world's oceans, and the second largest component of biomass after prokaryotes, where up to 9x108 virus, virions per millilitre have b ...
