Whup de doo, my first post Seriously, for all you biomedical experts out there, is it theoretically possible to genetically engineer bacteria to hunt pathogens for common human diseases? This would only work for bacteria-eating bacteria, (as far as I know there are no virus-eating bacteria), so this would elimnate a sizable number of ailments, from HIV to the common cold. For diseases such as Tuberculosis, however, couldn't you modify a common strain to hunt down the pathogen? First thread, so please, be gentle
