But though a marketable drug is a ways off, the breakthrough is significant. Many antibiotic drugs are susceptible to antibiotic resistance. Though the drugs kill most bacteria in a sample, the strongest survive and pass their resistant genes on to the next generation, creating a future generation that is not susceptible to the same drugs. This keeps drug makers perpetually behind the eight ball as they try to keep up with evolving bacterial strains. Since no bacteria are killed in the by the communications scrambling drugs, the problem of resistance is removed, or at least severely slowed. As such, running signal interference could very well help doctors gain the upper hand against a variety of common life-threatening bacteria like pneumonia, cholera and septicemia.
