Transcript text: 33. Antibiotics only effective against a single organism or disease.
a. broad spectrum
b. narrow spectrum
c. limited spectrum
Solution
The answer is the second one (b): narrow spectrum.
Explanation:
a. Broad spectrum: This refers to antibiotics that are effective against a wide range of bacteria, both Gram-positive and Gram-negative. Therefore, this option is incorrect for antibiotics effective against a single organism or disease.
b. Narrow spectrum: This refers to antibiotics that are effective against a specific type of bacteria or a limited group of organisms. This is the correct option for antibiotics that target a single organism or disease.
c. Limited spectrum: While this term might seem similar to narrow spectrum, it is not commonly used in the context of antibiotics. The correct term for antibiotics effective against a single organism is "narrow spectrum."
In summary, narrow spectrum antibiotics are designed to target specific bacteria, making them effective against a single organism or disease.
