Abstract

Biological indicators are provided for use in validating and routinely monitoring oxidizing gas sterilizations. The biological indicators are based on Bacillus circulans spores that are enclosed in packages with sufficient permeability to admit a sterilizing amount of vapor while being substantially bacteria impermeable.
