Study Notes
Emergence of Antimicrobial Resistance
- Penicillin and sulfonamides were discovered before the routine testing for susceptibility began in the 1950s.
Purpose of Antimicrobial Susceptibility Testing
- The purpose of antimicrobial susceptibility testing is to determine which antimicrobial drugs are effective against a particular microorganism.
Types of Resistance
- Inherent resistance is not necessary to test for in organisms, as it is a natural characteristic of the microorganism.
History of Antimicrobial Resistance
- Resistance to penicillin and sulfonamides began to emerge in the 1950s.
Impact of Penicillin and Sulfonamides
- The discoveries of penicillin and sulfonamides led to a significant shift in the treatment of infections, as they provided effective treatments against bacterial infections.
