What does it mean when an antibiotic has a narrow spectrum?

What does it mean when an antibiotic has a narrow spectrum?

An antibiotic may be classified as “narrow-spectrum” or “broad-spectrum” depending on the range of bacterial types that it affects. Narrow-spectrum antibiotics are active against a select group of bacterial types.

Why do we use narrow spectrum antibiotics whenever possible?

Narrow-spectrum antibiotics, like penicillin and amoxicillin, target only the bacteria known to cause a specific bacterial infection. Using these narrow-spectrum antibiotics whenever possible helps prevent the development of antibiotic resistance.

What is an example of narrow-spectrum antibiotics?

A narrow-spectrum antibiotic is an antibiotic that is only able to kill or inhibit limited species of bacteria. Examples of narrow-spectrum antibiotics include vancomycin, fidaxomicin and sarecycline.

What is the example of narrow-spectrum?

What is the difference between broad spectrum and narrow-spectrum antibiotics?

Narrow-spectrum antibiotics target a few types of bacteria. Broad-spectrum antibiotics target many types of bacteria. Both types work well to treat infections. But using broad-spectrum antibiotics when they’re not needed can create antibiotic-resistant bacteria that are hard to treat.

Which of the following is an example of narrow-spectrum antibiotic?

Examples of narrow-spectrum antibiotics include vancomycin, fidaxomicin, and sarecycline. Complete answer: Penicillin (PCN or pen) is a group of antibiotics originally extracted from popular moulds called penicillium moulds, including penicillin G, penicillin V, procaine penicillin, and penicillin benzathine.

What is the example of narrow-spectrum antibiotic?

What is the meaning of narrow-spectrum?

Medical Definition of narrow-spectrum : effective against only a limited range of organisms narrow-spectrum antibiotics effective only against gram-negative bacteria — compare broad-spectrum.

Why are broad spectrum antibiotics bad?

Broad-spectrum antibiotics are more likely to lead to bacteria that resist drugs. This leads to infections that last longer and cost more to treat. They can spread to family and friends. Antibiotics have side effects.

What are broad-spectrum antibiotics target?

A broad spectrum antibiotic acts against both Gram-positive and Gram-negative bacteria, in contrast to a narrow spectrum antibiotic, which is effective against specific families of bacteria. An example of a commonly used broad-spectrum antibiotic is ampicillin.
