The organisms were grouped by using distance matrices based on the sums of the differences from the other organisms for the 256 tetranucleotide combinations, as described in Materials and Methods. Phylogenies were created by neighbor-joining analysis. Colors indicate Myoviridae (contractile tails; blue), Podoviridae (short tail stubs; green), and Siphoviridae (long tails; red). Bootstrap values >50 based on 100 replicates are represented at each node, and the branch length index is indicated below the phylogeny. Bacteriophage source by host species – gram-positive bacilli, gram-positive cocci, gram-negative enterobacteria, and gram-negative non-enterobacteria are indicated by brackets.
