Detection and classification of Streptococcus agalactiae prophages by prophage type. Streptococcus agalactiae

Streptococcus agalactiae (group B Streptococcus, GBS) causes severe infections in humans and animals. Prophages have been reported to contribute to GBS evolution and pathogenicity. Prophages were searched and classified according to their prophage type (an integration of phylogenetic group and integrase type) in 615 public GBS genomes from humans and animals and 29 prophage types were found. One prophage of each type was selected as reference for further studies.
