Question

Quizplus · Accepted Answer

Phage typing is a method of identifying bacteria based on their susceptibility to specific bacteriophages (or bacterial viruses) that infect only particular strains or species of bacteria. Therefore, option C is the correct choice. Option A is incorrect because, although bacteriophages do destroy bacteria, this fact isn't the basis of phage typing. Option B is incorrect because not all viruses cause disease, and this is not a relevant aspect in phage typing. Option D is incorrect because although Staphylococcus is a type of bacteria that can cause infections, this fact is not related to phage typing. Option E is incorrect because although bacteriophages and bacteria are related in the sense that bacteriophages can infect and replicate in bacterial hosts, this fact is not related to phage typing.
