Which condition is most important for the recovery of anaerobic organisms from a wound specimen?
1Refrigeration of the specimen immediately after it is collected
2Collection on a dry cotton swab without medium
3Prompt transport in an oxygen-reduced transport system✓ 정답
4Incubation in a carbon dioxide incubator on arrival
해설
Anaerobes die quickly on exposure to oxygen, so the specimen must be placed in an oxygen-reduced transport medium and delivered without delay. Refrigeration reduces recovery, and a dry swab is the worst choice because it combines desiccation with oxygen exposure.
