Genetic Competence and Transformation in Oral Streptococci

Abstract: The oral streptococci are normally non-pathogenic residents of the human microflora. There is substantial evidence that these bacteria can, however, act as "genetic reservoirs" and transfer genetic information to transient bacteria as they make their way through the mouth, the principal entry point for a wide variety of bacteria. Examples that are of particular concern include the transfer of antibiotic resistance from oral streptococci to Streptococcus pneumoniae. The mechanisms that are used by oral streptoc… Show more

“…The ciaH and comC genes, which were both previously reported to regulate competence and biofilm formation (Cheng et al, 1997;Cvitkovitch, 2001;Havarstein et al, 1996;Li et al, 2001Li et al, , 2002Mascher et al, 2003;Qi et al, 2004;Yoshida & Kuramitsu, 2002) in several species of Streptococcus, also reduced the expression of the comY luciferase reporter. In addition, it was also found that the luxS mutation had an effect on competence similar to that of the comC mutation in both the luciferase and transformation assays.…”

“…Competence development in S. mutans is associated with a complex machinery, including membrane-localized and secreted components and a quorum-sensing signaling system (22). This machinery is specific for prokaryotes and is not present in mitochondria.…”

“…Low self-esteem, adverse pregnancy outcomes, increased risk of myocardial infarction, cardiovascular disease, respiratory, erectile, diabetes complications, cavernous sinus thrombosis and Ludwig angina are associated with dental caries which can be crucial to human beings [6][7][8]. Moreover, oral diseases hamper activities at school, at occupation and at residence causing millions of school and employment hours to be vanished each year throughout the globe [3,9].…”
