Question

1 multiple choice 0.8 points phage typing of a bacterial species involves the use of antibodies. gram staining the use of viruses. examination of key metabolic pathways each species uses. genetic techniques such as pcr and homology.

Explanation:

Phage typing is a method that uses bacteriophages (viruses that infect bacteria) to identify and classify bacterial strains. It is based on the specific interaction between phages and their host - bacteria. Antibodies are used in serotyping, Gram - staining is for differentiating bacteria based on cell - wall structure, examination of metabolic pathways is part of biochemical tests, and genetic techniques like PCR are used for DNA - based identification.

Answer:

C. the use of viruses.
