Abstract:
1. A sterilization indicator system, comprising: spores of one or more species of microorganism; a vial comprising an optional first compartment and a second compartment containing a growth medium comprising one or more of a disaccharide, an oligosaccharide or a polysaccharide capable of conversion to a monosaccharide by germinating spores of the one or more species of microorganism, the vial being adapted to combine contents of the second compartment with the spores for analysis after the vial has been exposed to a sterilant; a strip comprising two or more electrodes adapted to oxidize the monosaccharide and to carry an electrical signal resulting from the oxidation of the monosaccharide, wherein the two or more electrodes are adapted to provide contact with the combined contents of the second compartment and the spores during and/or after incubation; and an apparatus linked or linkable to the two or more electrodes and adapted to detect and measure the electrical signal resulting from electron transfer when the monosaccharide is oxidized by the two or more electrodes, wherein the system is free of the monosaccharide prior to exposure to the sterilant.
