FIG 6.

Prophages inserted between rlmCD and fosX belonged to the genus Siphovirus and have a broad host species range and a tendency to harbor antimicrobial or heavy metal resistance genes. Minimum evolutionary tree and taxonomic clustering of six Listeria-specific phages (genera 2 to 6), prophages from the strains HC134 and HC258 from this study that were inserted between rlmCD and fosX (genus 1, blue), and related prophages from Listeria and other Firmicutes species obtained from GenBank (genus 1, black). Phylogenetic analyses and clustering were generated with the VICTOR online tool (https://victor.dsmz.de), using model D₆ and 100 bootstrap replicates. The tree was visualized using FigTree 1.4.4. Bootstrap support values above 70 are shown.
