摘要： A biological sterilization indicator, system, and methods of determining the effectiveness of a sterilization process. The biological sterilization indicator can include a locus of spores, a reservoir containing a liquid, and a sterilant path positioned to provide fluid communication between ambience and the locus of spores. The reservoir can have a closed state in which the reservoir is not in fluid communication with the locus of spores and an open state in which the reservoir is in fluid communication with the locus of spores. The biological sterilization indicator system can include the biological sterilization indicator and a detection device adapted to be coupled to the biological sterilization indicator. In some embodiments, the method can include assaying the spores for a detectable change in a characteristic, and detecting substantially all of the detectable change.

摘要： A biological sterilization indicator (BI). The BI can include a housing, and a container positioned in the housing. The container can contain a liquid and at least a portion of the container can be frangible. The BI can further include a first chamber and a second chamber. The second chamber can include at least one source of biological activity. The BI can further include a substrate positioned in the housing between the first chamber and the second chamber. The substrate can be positioned in fluid communication with the first chamber and the second chamber, and the substrate can be further positioned such that the substrate is not in direct contact with the source of biological activity.
摘要翻译： 生物灭菌指示剂（BI）。 BI可以包括壳体和位于壳体中的容器。 容器可以容纳液体，容器的至少一部分可以是易碎的。 BI还可以包括第一室和第二室。 第二室可以包括至少一种生物活性来源。 BI还可以包括位于第一室和第二室之间的壳体中的衬底。 衬底可以定位成与第一腔室和第二腔室流体连通，并且衬底可以进一步定位成使得衬底不与生物活性源直接接触。

摘要： A biological sterilization indicator (BI) and a method of using same for assaying the lethality of a sterilization process. The BI can include a housing, which can include a first portion, and a second portion, which can be movable with respect to the first portion between a first and second position. The BI can further include a frangible container comprising a liquid. The BI can further include a spore reservoir and a projection positioned in the housing. The projection can be configured to fracture the container when the second portion of the housing is moved from the first position to the second position. The method can include maintaining a minimal cross-sectional area of space around the container when the second portion of the housing is in the first position, and fracturing the container in response to moving the second portion between the first and second positions.

The container can contain a liquid and at least a portion of the container can be frangible. The BI can further include a first chamber and a second chamber. The second chamber can include at least one source of biological activity. The BI can further include a first fluid path positioned to fluidly couple the first chamber and the second chamber, and a second fluid path positioned to allow displaced gas to move out of the second chamber. The method can include moving displaced gas out of the second chamber via the second fluid path as a sterilant is moved into the second chamber via the first fluid path and/or as the liquid is moved into the second chamber via the first fluid path.

摘要： A first aspect of the present invention provides for devices to facilitate the release of sample materials from sample acquisition devices. The device comprises an abrasion element comprising at least one constriction or projection. A second aspect of the present invention provides for methods in which to use the devices to facilitate the release of sample materials from a sample acquisition device. Optionally, the device may contain at least one reagent to facilitate the release and/or detection of a microorganism, or component thereof, in a sample. Preferably, the devices and methods may be used in conjunction with a liquid medium in which the sample may be further processed.
