Lately, CRISPR has been considered to do miracles in regard to curing diseases.

As a dentist/scientist, one of the main problems we face are caries.

The responsible bacteria is called Streptococcus mutans.

Can CRISPR be used to eliminate this type of bacteria ??


CRISPR is used to alter or delete a gene or a stretch of DNA. It can't be used (at least at present) to eliminate a whole species of bacteria.

There are some early strategies using CRISPR to target drug-resistant bacteria (e.g., by ‘attacking’ antibiotic resistant gene repertoire). One problem are current delivery systems and whether they will be ‘fast’ enough to overcome a quickly evolving bug population. see - … nd-Phages/ … .1198.html
