Question

Antibiotics that affect various strains of Gram-positive bacteria and various strains of Gram-negative bacteria are called?

1) isolate usable
2) stress-induced
3) narrow-spectrum
4) broad-spectrum

Answer 1

Antibiotics that target both Gram-positive and Gram-negative bacteria are known as broad-spectrum antibiotics.

Step-by-step explanation:

Antibiotics that affect various strains of Gram-positive bacteria and various strains of Gram-negative bacteria are called broad-spectrum antibiotics. These antibiotics work against a wide range of taxonomic groups, and they are ideal for use as empiric therapy to cover a broad range of potential pathogens while awaiting laboratory identification of the infecting pathogen. Broad-spectrum antibiotics are also used for mixed infections or as prophylactic measures to prevent an infection.
