The cytotoxicity of the CDCs is sensitive to the modifications in this region, especially mutations of the tryptophan or the cysteine residues highly affect its binding capacity, for example, intermedilysin (ILY) secreted by Streptococcus intermedius
has an alanine residue instead of cysteine of the conserved region, resulting in an oxidation-resistant toxin and a proline residue is present in place of second conserved tryptophan .
Two days later, the cultures from the biopsy were finalized revealing growth of Streptococcus intermedius
is part of the Streptococcus anginosus subgroup (formerly Streptococcus milleri) [1-4].

In addition, the following periodontal pathogens were assessed by DNA probe before treatment, 2 days after treatment, and 1 month following treatment: Porphyromonas gingivalis (PG); Prevotella intermedia (PI); Tannerella forsythensis (Tf); Aggregatibacter (formerly Actinobacillus) actinomycetemcomitans (Aa); Fusobacterium nucleatum (Fn); Treponema denticola (Td; Peptostreptococcus micros (PM); Camplyobacter rectus (Cr); Eikenella corrodens (Ec); Selenomonas noxia (Sn); and Streptococcus intermedius
