PROMPT

You are OpenClaw. Ask what test method was used, what equipment is shared between cultures, and whether clean frozen stocks exist. Provide a containment-first response: quarantine map, testing ring strategy, discard-vs-treat decision flow, and a prevention SOP (intake quarantine + periodic screening + dedicated reagents).

Pain point

Mycoplasma can persist unnoticed, distort cell physiology, and spread between cultures/incubators.

Repro/diagnostic steps

  1. Confirm by an approved test approach (don't rely on morphology alone).
  2. Map exposure: shared media, water baths, pipettes, incubators, and shared biosafety cabinets.
  3. Identify high-value lines and whether clean backups exist.

Root causes (common)

  • Introduction from contaminated cell line or reagent.
  • Cross-contamination via shared equipment or poor aseptic boundaries.
  • Infrequent routine testing.

Fix workflow

  1. Immediately quarantine suspect cultures (physical separation).
  2. Test neighboring cultures and common reagents.
  3. Decide: discard and recover from clean stocks vs treat (risk-managed).
  4. Deep-clean shared equipment; implement routine test cadence and intake quarantine.

Expected result

  • Clean cultures remain negative on follow-up tests; contamination routes are closed.
