Complete genome sequence analysis of a novel Staphylococcus phage StAP1 and proposal of a new species in the genus Silviavirus.

Bacteriophage StAP1 was isolated from a soil sample infecting Staphylococcus aureus and S. xylosus. Its genome was found to be 135,502 base pairs (bp) long with 30.00 mol% G+C content and 192 open reading frames. While no tRNA encoding genes were identified, 7 mobile elements were found to interrupt five StAP1 open reading frames. Comparative genomic and proteomic analysis consistently supports the establishment of a new species in the genus Silviavirus.
