Study Notes
Antibiotic Characteristics
- Beta-lactam antibiotics, such as penicillins and cephalosporins, primarily target Gram-positive organisms.
- Bacteriostatic antibiotics inhibit the growth or reproduction of bacteria, preventing them from multiplying.
- Bactericidal antibiotics kill bacteria directly, eliminating them from the system.
- Broad-spectrum antibiotics are effective against both Gram-positive and Gram-negative bacteria, providing comprehensive coverage.
- The characteristic of an antibiotic selectively inhibiting or killing microorganisms is referred to as selective toxicity.
