“…The genome sequence of the virulent phage M102, which infects S. mutans, has recently been published (van der Ploeg, 2007). The sequenced genomes of three oral streptococcal strains, including S. gordonii CH1, do not appear to contain prophages (Ajdić et al, 2002;Tanzer et al, 2008;Vickerman et al, 2007;Xu et al, 2007). Temperate phages from Streptococcus mitis, an abundant inhabitant of the oral cavity, have been described (Romero et al, 2004a;Siboo et al, 2003).…”
