Bacteria agents acting against

Viruses and bacteria are potential agents for treating cancer if they can be made to act selectively against cancer cells, that is, if they can work as pathogens for cancer cells only. Thus, the bacteria known as BCG, for Bacillus Cahnette-Guerin, is a weakened strain of the microbe Mycobacterium bovis, which is used worldwide as a vaccine for tuberculosis. BCG is said to stimulate the immune system and thereby act against cancer. The treatment is described, for instance, in Ralph Moss...

The immobilization of antibacterial components in the resin matrix has been another attempt to modify resin components to render restorative materials caries-resistant. This approach is used to obtain antibacterial composites that do not release any antibacterial component Rather, the immobilized agent acts as a contact inhibitor against bacteria attaching the material surface [32]. 

T. is an antibiotic substance produced by Strepto-myces spp., e.g., Streptomyces viridifaciens fermentation with Streptomyces rimoses leads to 5-hydroxy-t. (= oxytetracycline), with Streptomyces aureofaciens, 7-chlorotetracycline (= aureomycine) is obtained. Its hydrochloride, the phosphate complex and its lauryl sulfate complex are used as antibacterials against gram-positive as well as gram-negative bacteria t. acts as an anti-amebic and anti-rickettsial agent.
