Principles of Antibiotic Resistance
Because of their short dividing time (E. coli replicate approximately every 30 min) and their ability to accept DNA from other bacteria or phages, most bacteria are capable of becoming resistant to antibiotics very quickly. The history of antibacterial therapy is characterized by the fact that every time a new antibacterial agent is introduced, the organisms become resistant. The exception to this rule includes syphilis which has remained sensitive to penicillin for over 50 years since the introduction of this agent. N. gonorrhea and S. aureus, which became resistant within a few years after the introduction of penicillin, represent the more common response of bacteria to the introduction of an agent.
