The Tevenvirinae are a subfamily of viruses in the order Caudovirales , family Myoviridae . Bacteria and archaea serve as natural hosts . There are currently about 54 species (species) in this subfamily, most of which are assigned to one of 11 genera. The subfamily Tevenvirinae is to be distinguished from the sometimes used English name T-even bacteriophages for the species Escherichia virus T4 contained in it with the subtypes T2, T4, T6,….

construction
The virus particles (virions) of the Tevenvirinae are not enveloped and have head-tail geometries. They are about 70 nm wide and 140 nm long. The genomes are linear and approximately 170–245 kb in length . The virus genome encodes around 300 to 415 proteins .
Propagation cycle
Virus replication takes place in the cytoplasm of the host cell (the bacterium or archaeon). Entry into the host cell occurs through adsorption. The virus emerges from the host cell through lysis (dissolution of the host cell, ie its outer membrane). The transmission occurs through passive diffusion .
