Question
Answer
Title: Antibiotic Susceptibility Testing of Staphylococcus

The antibiotic susceptibility testing results of Staphylococcus showed zones of inhibition (absence of growth on zones) around disks of Penicillin, Tetracycline, and Chloramphenicol. This means:

- **S. aureus is resistant to all these antibiotics.** (Selected Option)
- S. aureus is susceptible to all these antibiotics.
- Susceptible to only a couple of them.
- Neither are the correct choices.

Explanation: In the context of this question, zones of inhibition are measured to determine the effectiveness of antibiotics against bacteria. Larger zones indicate susceptibility, whereas absence or very small zones indicate resistance. The selected answer indicates that Staphylococcus aureus does not show growth inhibition, suggesting resistance to these antibiotics.
