Herelleviridae
''Herelleviridae'' is a family of bacterial viruses of the order ''Caudovirales'' infecting members of the phylum Firmicutes. The family has five subfamilies, 33 genera and 92 species. __TOC__ Etymology The family's name, ''Herelle'' is in honor of Félix d'Hérelle, a French-Canadian microbiologist A microbiologist (from Ancient Greek, Greek ) is a scientist who studies microscopic life forms and processes.

There are currently five species in this subfamily, divided among 2 genera. Taxonomy Group: dsDNA Structure Viruses in the subfamily ''Spounavirinae'' are non-enveloped, with icosahedral and Head-tail geometries, and T=16 symmetry. The diameter is around 84-94 nm, with a length of 140-219 in length, contractile with globular structures at its tip, has 6 long terminal fibers, 6 short spikes and a double base platenm. Genomes are circular, around 130-160kb in length. The genome codes for 190 to 230 proteins. Life cycle Viral replication is cytoplasmic. Entry into the host cell is ach ...

Okubovirus
''Okubovirus'' is a genus of viruses in the order ''Caudovirales'', in the family ''Herelleviridae'', in the subfamily ''Spounavirinae''. Bacteria serve as natural hosts. There are two species in this genus. Taxonomy The following two species are assigned to the genus: * '' Bacillus virus Camphawk'' * ''Bacillus virus SPO1'' Structure Viruses in ''Okubovirus'' are non-enveloped, with head-tail geometries, and T=16 symmetry. The diameter is around 108 nm, with a length of 140 nm. Genomes are linear, around 145kb in length. The genome codes for 200 proteins. Life cycle Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion. Taxonomic history * ''Bacillus phage SP8'' was assigned to the family Myoviridae in 1995. * ''Bacillus phage SPO1'' was assigned to the genus SPO1-like phages ...

Félix D'Hérelle
Félix d'Hérelle (25 April 1873 – 22 February 1949) was a French microbiologist. He was co-discoverer of bacteriophages (viruses that infect bacteria) and experimented with the possibility of phage therapy. D'Herelle has also been credited for his contributions to the larger concept of applied microbiology. Biography Early years Félix d'Hérelle's father, Hubert Augustin Félix Haerens d'Herelle, died at the age of 30 when Félix was six years old. From 7 to 17 years of age, d'Hérelle attended school in Paris, including the Lycée Condorcet and Lycée Louis-le-Grand high schools. In the fall of 1891, d'Hérelle traveled to Bonn, Germany where he attended lectures at the University of Bonn for several months. Between the ages of 16 and 24, d'Hérelle traveled extensively via money given by his mother. At 16, he started to travel through western Europe by bike. At 17, after finishing school, he traveled through South America. Afterwards, he continued his travels through E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
