Resistance to drugs and poisons
Coyne says that "in 1941, [penicillin] could wipe out every strain of staph in the world. Now, seventy years later, more than 95 percent of staph strains are resistant to penicillin" (131). It is very evident that antibiotics are rapidly losing their effectiveness against bacterial infections. Scientists as of now have been able to produce new types of antibiotics that bacteria aren't resistant to, but they are rapidly running out of new kinds. Also, the use of bacteriophages to kill pathogenic bacteria is an area of extensive research to cure infections. What are some ways that scientists are trying to apply the use of bacteriophages to cure sicknesses, and what are other methods which biologists are researching to cure infections? Have there been any recent advances in the treatment of viral infections?
