Genus: Pecentumvirus

Distinguishing features

The genus description and subfamily description are currently the same, i.e. the subfamily only contains one genus and there are no unassigned species. 

Members of this genus infect Listeria monocytogenes. The type species is Listeria virus P100. The genome of the exemplar isolate of the type species is 131 kbp, with 193 gene coding sequences, as well as 18 encoded tRNAs.

Biology 

Members of the genus infect Listeria monocytogenes. 

Derivation of names

Pecentumvirus: derived phonetically from the name of the exemplar isolate, Listeria phage P100, of the type species (“pe” followed by centum meaning 100 in Latin). 

Species demarcation criteria 

Members of the same species are more than 95% identical in genome nucleotide sequence, including the terminal repeat region. Phages with genomes that differ by more than 5% are assigned to different species.
