Beyond the Chromosome: The Prevalence of Unique Extra-Chromosomal Bacteriophages with Integrated Virulence Genes in Pathogenic Staphylococcus aureus
Figure 2
Identification and classification of contig sequences that contain phage genes and other genetic elements from S. aureus extra-chromosomal DNA.
BLAST nucleotide sequence analysis identified the sequence identity of contigs generated from S. aureus extra-chromosomal DNA. Contigs were labeled based on homology to published nucleotide sequences: bacteriophage (black), plasmid (green), transposon/insertion sequences (IS) (blue), or not in GenBank database (n/a; purple). Contigs were labeled transposon/(IS) if a transposon or insertion element was unassociated or associated with plasmid or chromosome. Numbers above rectangular bars represent the total contigs within an individual sequencing sample. Y-axis lists total contigs identified as mobile genetic elements (MGE) based on BLAST homology identifications.
