Discussion
Consider the following statements about aseptic technique.
1. Work is carried out in a laminar flow hood.
2. Surfaces and gloves are disinfected before starting.
3. Antibiotics remove the need for careful technique.
Answer: B
The first two are standard practice. The third is exactly the attitude that antibiotic use is criticised for encouraging, since a drug controls some organisms rather than preventing contamination. Technique, not chemistry, is what keeps a culture clean.
