Comparative analysis of the genomes of the temperate bacteriophages phi 11, phi 12 and phi 13 of Staphylococcus aureus 8325.

The genomes of the three temperate bacteriophages contained in the chromosome of Staphylococcus aureus 8325 have been extracted from the sequence database and analyzed. phi 11, phi 12 and phi 13 are members of the same lytic group but different serogroups and consequently co-habitate the same host cell. Their genomes are approximately 42 kb to 45 kb and contain about 90 ORFs of at least 50 codons.
