    摘要: A sterilization indicator for oxidative sterilants, comprising a first compartment comprising spores of one or more microorganism species, wherein the spores have been pretreated with and comprises a compound comprising a transition metal ion that is reactive with an oxidative sterilant; a second compartment comprising a growth medium and adapted to combine contents of the first compartment with contents of the second compartment for incubation after the sterilization indicator has been exposed to an oxidative sterilant; and an agent disposed in the growth medium and selected to indicate viability of the spores after the sterilization indicator has been exposed to the oxidative sterilant.

    摘要: A process for determining the viability of a biological indicator includes exposing the biological indicator to a viability detection medium, the biological indicator including test microorganisms, the exposing the biological indicator to the viability detection medium producing a gaseous reaction product when one or more of the test microorganisms are viable. The presence or absence of the gaseous reaction product produced by the biological indicator combined with the viability detection medium is detected with a sensing device, the sensing device comprising a resistive sensor, wherein the presence of the gaseous reaction product indicates the presence of viable test microorganisms and the absence of the gaseous reaction product indicates the absence of viable test microorganisms. A sterilization detection device includes a container configured to contain the biological indicator, a viability detection medium, and the sensing device.

    摘要: This invention relates to a biological indicator derived from a composition comprising: a host organism comprising a spore forming bacteria; a reporter gene for producing an indicator enzyme; a regulatory gene; and a vehicle for inserting the reporter gene and the regulatory gene in the host organism; the host organism bearing a transposable genetic element in its genome for inserting an insertion sequence in the regulatory gene; the insertion sequence comprising a transposase, a pair of terminal inverted repeat sequences, and at least one open reading frame for expressing the transposase. The vehicle may be taken up by the host organism. The insertion sequence may be inserted in the regulatory gene. The host organism may undergo sporulation to form the biological indicator. A process and an apparatus for using the biological indicator are disclosed.

    摘要: A combined sterilization indicator incubator and reader system, including a sterilization indicator vial containing one of a variety of selected biological indicators and a liquid, at least two incubator blocks, each incubator block independently operable to incubate the sterilization indicator vial at a plurality of independently selectable temperatures, each of the incubator blocks including at least one heating element operable to heat the incubator block to any one of the plurality of independently selectable temperatures; a light source, a photodetector and a control system configured to operate the combined system to determine the efficacy of a variety of sterilization processes. The system calculates and compares a slope to a predetermined threshold slope for the biological indicator, and provides output based only on the comparison of the calculated slope to the predetermined threshold slope without first determining either a baseline or a minimum value of the output from the photodetector.

    摘要: A sterilization indicator system and method of using the system to determine efficacy of a sterilization process. The system may include a vial having an optional first compartment and a second compartment comprising 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 free of the monosaccharide prior to use; a strip including two or more electrodes to oxidize the monosaccharide and to carry a resulting electrical signal, and an apparatus to detect and measure the electrical signal resulting from the oxidation. Spores of a suitable biological indicator may be disposed in the first compartment and/or on the strip.
