Study summary

We are studying the possibility of using dental calculus as a reservoir for the genes of an infectious agent that has infected the patient in previous months; as it is done to highlight climate change in ice samples.

Read the detailed description

From a sample of people who have had a microbiologically well-documented infection, we will study the possibility after genomic amplification to find, three to 12 months after genetic sequences of the infectious agent in the dental calculus of the person. The people will be recruited according to a large panel of infectious agent (gram + and gram bacterium, mycobacteria, parasite, fungus, DNA, RNA or retrovirus) and, of course, the presence of dental calculus.
