Question

5 multiple choice 1 point phage typing is based on the principle that: phages can replace antibiotics each bacteriophage infects a specific bacterial strain viruses only infect eukaryotic cells all bacteria are equally sensitive to the same phage

Explanation:

Phage typing relies on the fact that bacteriophages (phages) have a specific host - range and each phage infects a particular bacterial strain. This allows for the identification and classification of bacteria. Phages cannot replace antibiotics in general, viruses can infect prokaryotic (bacterial) cells too, and not all bacteria are equally sensitive to the same phage.

Answer:

B. Each bacteriophage infects a specific bacterial strain
