Abstract

Microwave exposure (90 s) provides an effective, rapid sterilization for surgical scalpel blades which have been contaminated with Candida albicans. SEM analysis showed that microwave irradiation induced a morphological modification of the cells. The longer the exposure time the greater such alterations and this micro-organism in effect fractures after 9 min. No evidence was found of morphological alteration of the fungus after being submerged in boiling water for the same amount of time even though cell death was actually achieved.

Main findings

Microwave exposure for 90 seconds was reported to provide rapid sterilization of scalpel blades contaminated with Candida albicans. SEM analysis indicated microwave irradiation induced time-dependent morphological modifications, with greater alterations at longer exposures and apparent fracturing after 9 minutes; boiling water for the same duration achieved cell death but showed no morphological alteration.

Outcomes measured

  • Sterilization/cell death of Candida albicans on contaminated surgical scalpel blades
  • Cell morphology changes (SEM)

Limitations

  • In vitro study on a microorganism; findings may not generalize beyond the described sterilization context
  • Microwave exposure parameters beyond duration (e.g., frequency, power, SAR) are not reported in the abstract
  • Sample size and experimental controls are not described in the abstract
