Isolation of Streptococcus mutans temperate bacteriophage with broad killing activity to S. mutans clinical isolates.

ABSTRACT: Bacteriophages are expected to be therapeutic agents against infectious diseases. Streptococcus mutans are involved in dental plaque formation related to dental caries and periodontitis. In S. mutans, lytic bacteriophages have been isolated previously, but the isolation of temperate bacteriophage has not been reported although their presence in the genome has been confirmed. Here, we report the isolation of temperate bacteriophage, φKSM96, from S. mutans. φKSM96 has a circular DNA 39,820 bp long and reveals Siphoviridae morphology. φKSM96 shows a broad range of susceptibility against S. mutans strains with different serotypes. By the addition of φKSM96, S. mutans growth and biofilm formation were significantly inhibited. In cocultures of S. mutans
