1. USP recommends using three specimens of the relevant biological indicator for determining a total viable spore count.
2. Perform population count on three separate biological indicators and average counts.
3. Mesa has validated that using 10 specimens of the relevant biological indicator gives equivalent results as the USP recommended three specimens.
Biological Indicators D-value and Population Verification/Assessment (Third party testing and assessment/verification testing results and what can and can not be done with this data.)
Biological Indicators / D-value Verification (Provides information pertaining to the critical parameters necessary to perform a D-value assessment and why it may be so difficult to obtain a 3rd party verification of the D-value on Biological Indicators.)
Micro-Lab / Medical Waste Sterilization Made Easier (Provides information on why one must use a sealed BI in waste sterilization and the easy way to accomplish such use.)
Monitoring Bio/Med Waste Bags with Spore Strips as Biological Indicators and ‘False’ Negatives (It has been noted that a fairly large number of facilities use spore strips as their Biological Indicator (BI) for the monitoring of biowaste bags to be steam sterilized.)
Steam Sterilization and BI Monitoring Liquid Loads (Information on liquid cycle sterilization, use of sealed glass ampoules, possible causes for a failed cycle and information on why the ampoule BI should sink in the liquid being sterilized and not float on the surface.)
Sterilization Monitoring – Validation of Liquid Loads Managing Infection Control 2002 (Sterilization Monitoring and Validation of Liquid Loads in Steam Autoclave Cycles and the Importance of Appropriate BI Selection and Resistance.)
Unique Cycles – Sterilizing Liquid Loads (With liquid loads there are no concerns about pre-vac air-removal or steam penetration as into a porous load, so why do so many problems occur with liquid media sterilization and BI lethality?)
