Apply a disinfectant, kill the germs — right?   It's not that easy.  With the advent of modern disinfectants, many of us may feel a false sense of security when using germicides.  However scientists are finding germs are apparently smarter, tougher and more organized than anyone ever imagined.  Recent discoveries have shown that bacteria on damp surfaces do not remain as isolated and free floating life forms but communicate and colonize with other germs to build a tough, protective biofilm that can withstand even the strongest disinfectants.
