Glossary Terms (Simple List)
-
Biological Indicator (BI)
An inoculated carrier contained within its primary pack ready for use and providing a defined resistance to the specified sterilization process. (TR51)
-
Biological Indicator (BI) Challenge System
A test system containing viable microorganisms of a pure and specified strain providing a defined resistance to a specified sterilization process (TR1)(TR3) (TR30) (TR61)
-
Biological Medicinal Product
A product (therapeutic or prophylactic) for human use that has been manufactured in or from a biological source. Examples include recombinant therapeutic proteins or vaccines. Biological medicinal products are also referred to as: biological medicines, biological products, biologics and biologic drugs. (TR 71)
-
Biological Qualification
A component of performance qualification that demonstrates, by use of biological indicators, that the required lethality (FBIO) is achieved consistently throughout the load. (TR1) (TR3) (TR30)
A component of performance qualification that demonstrates, by use of biological indicators, that the required lethality (FBIO) or spore log reduction (SLR) is achieved consistently throughout the sterilized or sanitized portion of the SIP system. (TR61)
-
Biological Safety Cabinet (BSC)
An enclosed, ventilated workspace with engineering controls designed to remove or minimize exposure to hazardous biological materials. A BSC is a principle device to provide containment of infectious splashes or aerosols generated by many microbiological procedures. BSCs are designed to provide personnel, environmental and product protection when appropriate practices and procedures are followed. A cabinet that is designed to protect the operator and the environment from the hazards of handling infected material and other dangerous biological. (TR62)
-
Biological Tests
Biological tests include animal, cell culture, or biochemical based testing that measures a biological, biochemical, or physiological response. (TR38)
-
Biologics License Application (BLA)
An application, filed with the US Food and Drug Administration (FDA), which contains specific information on the manufacturing processes, chemistry, pharmacology, clinical pharmacology and the medical effects of the biologic product (similar function as the Marketing Authorization Application in Europe). (TR56)
-
Biomethylation
The enzyme chlorophenol o-methyltransferase responsible for fungal methylation has been isolated in cell-free extracts. Biomethylation, in this context, may be seen as a detoxification mechanism, although it plays a role in the production of mycotoxins by secondary metabolism. Slightly xerophilic fungi frequently associated halophenol biomethylation include Trichoderma longibrachiatum, Trichoderma virgatum, Aspergillus sydowii, and Penicillium islandicum. (TR55)
-
Blank
Analytical sample taken to establish background value for the analytical measurement which may be subtracted from an experimental value to determine the “true” value. (TR29) (TR49)
-
BLAST
Basic Local Alignment Search Tool; a bioinformatics algorithm for the comparison of sequence data (e.g., translated amino acids [tBLASTx], proteins [BLASTx], or nucleotides [BLASTn]). (TR 71)
