Infectious nature

Infectious nature The transmissible infectious nature of dental caries caused by estreptococcus of mutans was demonstrated through experiments in mice and hamsters, conducted by researchers at Americans, Paul Keyes and Robert Fitzgerald, from the 1950s. Through these studies, these researchers demonstrated that dental caries is an infectious disease, caused by micro-organisms transmissible, described for the first time in 1924, by Clarke, England the Streptococcus mutans.

Because of evidence that s. mutans is the major pathogen responsible for the development of dental caries, this is currently one of the most researched species. A strain of s. mutans, isolated by researcher Page w. Caufield, an American child with high rates of dental caries an University of Alabama in 1982, he was selected for seqüêciamento of its genome. The genome sequence of s. mutans UA159 strain was published in 2002 in the Procedings of the scientific journal Nature Academy of Science. The genome data are available for the whole scientific community in the public database GenBank, being that anyone can access it through the site, created by the u.s. Government. Today, any one of us can see the genetic code of this species pathogenic. The genome of s. mutans is organized into a single genetic code this species pathogenic. The genome of s. mutans is organized in a single circular chromosome that is approximately 2.03 million base pairs (Mb). This chromosome were identified a total of 1960 genes that encode proteins and 80 that encode RNAs ribossômicos and RNAs transporters. Several scientific studies have been conducted to examine the participation of several genes of s. mutans in virulence characteristics.
