Question

a strain of heat - tolerant pathogenic bacteria has acquired resistance to all known antibiotics. which method would you propose to best control its future spread? the development and application of metabolically inactive nutrient analogues heat sterilization of affected areas the introduction of nonpathogenic bacteria to compete with the pathogen for resources the development of a new class of antibiotics that the pathogen has not yet encountered the introduction of a bacteriophage that is known to attack a closely related bacterial species

Explanation:

Phages are viruses that infect bacteria. Introducing a bacteriophage that attacks a closely - related bacterial species can target the pathogen. New antibiotics may not work if the pathogen has resistance mechanisms. Non - pathogenic bacteria competition may not be sufficient. Heat sterilization is not a practical long - term solution for controlling spread. Metabolically inactive nutrient analogues may not directly control the pathogen's spread. Bacteriophages can specifically target and lyse the pathogen.

Answer:

The introduction of a bacteriophage that is known to attack a closely related bacterial species
