..., Finkel said. Biofilms, which have been linked to chronic infections, also may harbor nutritionally competent germs. If researchers succeeded in turning off nutritional competence in such pathogens, as Finkel did in E. coli, the advance might lay the groundwork for a new class of genetic antibiotics. The ...

First human study confirms that immune cells can be a primary cause of bone loss in gum disease

B cells are known to produce a weapon (antibody) that normally attacks bacteria and protects our body from bacterial infection. As a consequence of dense infiltration of B cells found in the gum, periodontally diseased patients m...
