Streptococcus gordonii : ウィキペディア英語版 | Streptococcus gordonii ''Streptococcus gordonii'' is a Gram-positive bacterium included among some of the initial colonizers of the periodontal environment. 〔American Academy of Periodontology 2010 In-Service Exam, question 82〕 The organism, along with related oral streptococci, has a high affinity for molecules in the salivary pellicle (or coating) on tooth surfaces. ''S. gordonii'' therefore can rapidly colonize clean tooth surfaces, and ''S. gordonii'' along with related organisms comprise a high percentage, up to 70%, of the bacterial biofilm that forms on clean tooth surfaces. Generally harmless in the mouth, ''S. gordonii'' can cause acute bacterial endocarditis upon gaining access systemically. ''S. gordonii'' also forms an attachment substratum for later colonizers of tooth surface and can modulate the pathogenicity of these secondary colonizers through interspecies communication mechanisms. ==References==
