USP <60>, <61> and <62> describe the suitability tests necessary for each analysis. The correct inoculum of not more than 100 CFU is required in addition to specific incubation temperatures and durations. Ensure that seed- lot cultures used are not more than five passages removed from the original master seed-lot. For in-house prepared test strain suspensions of vegetative bacteria and yeast should be used within 2 hours, or within 24 hours if refrigerated between 2ºC and 8ºC. Spore suspensions (A. brasiliensis, B. subtilis, and C. sporogenes) can be prepared and maintained between 2ºC and 8ºC for up to seven days. Additionally, all bacterial and spore suspensions should be prepared to yield ≤100 CFU. If commercially available ready-to-use bacteria or fungal suspension are used, then the manufacturer’s instructions should be followed with respect to preparation and storage requirements. USP <60>, <61> and <62> require a control which is without test material to be included in the suitability test. The following viable ATCC derived cultures may be used. Please be aware that under the Microbiological Examination of Nonsterile Products chapters <60>, <61> and <62> users are allowed alternative sources of the below listed strains. The organisms below are recommended for ORS use in order to have a consistent and standard worksheet format: USP <60>: Burkholderia cepacian (ATCC 25416) Burkholderia cenocepacia (ATCC BAA-245) Burkholderia multivorans (ATCC BAA-247) USP <61>: Pseudomonas aeruginosa (ATCC 9027) Staphylococcus aureus (ATCC 6538) Bacillus subtilis (ATCC 6633) Candida albicans (ATCC 10231) Aspergillus brasiliensis (ATCC 16404) USP <62>: Pseudomonas aeruginosa (ATCC 9027) Staphylococcus aureus (ATCC 6538) Escherichia coli (ATCC 8739) |
