Study Notes
Antimicrobial Spectrum of Antibiotics
- The antimicrobial spectrum of an antibiotic refers to the range of microorganisms that are susceptible to its antibacterial activity.
Characteristics of Broad-Spectrum Antibiotics
- Broad-spectrum antibiotics are characterized by their ability to inhibit the growth of a wide range of microorganisms, including Gram-positive and Gram-negative bacteria, as well as some fungi and protozoa.
Significance of Narrow-Spectrum Antibiotics
- Narrow-spectrum antibiotics are important because they allow for targeted treatment of specific infections, reducing the risk of disrupting the natural balance of microbial flora in the body.
Determination of Antimicrobial Spectrum
- The antimicrobial spectrum of an antibiotic is determined through laboratory tests, such as the Kirby-Bauer disk diffusion test, which measures the zone of inhibition around an antibiotic disk.
Consequences of Indiscriminate Use of Broad-Spectrum Antibiotics
- The indiscriminate use of broad-spectrum antibiotics can lead to the development of antibiotic-resistant microorganisms, making them less effective against future infections.
