There was always a new antibiotic being developed to combat them. But, by the end of the 1960s, new classes of antibiotics were no longer being developed. Instead, most work involved slightly altering existing antibiotics to reduce toxicity and to revive drugs rendered ineffective by the emergence of resistance.
How has antibiotics developed over time?
Antibiotic resistance evolves naturally via natural selection through random mutation , but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange.
