Isolation of a Novel Lytic Bacteriophage against a Nosocomial Methicillin-Resistant Staphylococcus aureus Belonging to ST45

Figure 2

Phylogeny tree of R4 phage. Genome-BLAST Distance Phylogeny (GBDP) tree inferred using the formula D0 and yielding average support of 2%. The numbers above branches are GBDP pseudobootstrap support values from 100 replications. The branch lengths of the resulting VICTOR trees are scaled in terms of the respective distance formula used. The OPTSIL clustering yielded twenty species clusters, one cluster at the genus level, and one at the family level. Accession numbers are indicated next to the phage names. R4 phage is marked with a black asterisk.
