Definition of Narrow-Spectrum Antibiotic:
A narrow-spectrum antibiotic like X is one that is effective against only a limited number of specific types of harmful microbes and cells.

Characteristics of a Narrow-Spectrum Antibiotic:
- Targeted Action: Narrow-spectrum antibiotics target a specific group of bacteria or microbes, unlike broad-spectrum antibiotics that target a wide range of bacteria.
- Limited Range: These antibiotics are effective against a narrow range of pathogens, which can be beneficial in avoiding unnecessary disruption to the body's normal flora.
- Selectivity: Narrow-spectrum antibiotics are selective in their action, making them suitable for treating infections caused by specific types of bacteria while minimizing the risk of developing antibiotic resistance.

Example of Usage:
A narrow-spectrum antibiotic like X would be prescribed when the specific microbe causing an infection has been identified through diagnostic testing, allowing for targeted treatment without affecting other beneficial bacteria in the body.

Importance of Narrow-Spectrum Antibiotics:
- Reduced Side Effects: By targeting only the specific pathogen causing the infection, narrow-spectrum antibiotics can reduce the risk of side effects and disturbances to the body's microbiome.
- Minimizing Resistance: Limiting the use of broad-spectrum antibiotics in favor of narrow-spectrum options can help slow down the development of antibiotic resistance, preserving the effectiveness of these medications for future use.
In conclusion, antibiotic X is classified as a narrow-spectrum antibiotic due to its targeted action against specific types of harmful microbes and cells, making it a valuable option for treating infections without broad disruption to the body's microbiome.
