Stability of Bacillus pumilus spore strips used for monitoring radiation sterilization.
Dried Bacillus pumilus spore strips had a stable D-value of 0.17 to 0.18 Mrad after 1 year at 5 or 25 C, but resistance was lost at 35 C. Refrigeration did not have an adverse effect on resistance to irradiation. The presence of water at the time of initial preparation increased this resistance to 0.23 to 0.25 Mrad. Proper drying is essential to achieve reproducible results in sterility tests u...
متن کاملEvaluation of new technique of sterilization using biological indicator
Background A novel technique of sterilization of endodontic files is introduced in this article. Aims Newly introduced sterilization unit, named "SteriFast" is compared with autoclave and glass bead sterilizer using biological indicator. Materials and Methods Spore strips of Bacillus pumilus were cultured in nutrient broth. This cultured media was used to contaminate the experimental sample...
متن کاملA Novel Biological Dosimetry Method for Monitoring Occupational Radiation Exposure in Diagnostic and Therapeutic Wards: From Radiation Dosimetry to Biological Effects
Background and Objective: Professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. Occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. Biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects....
متن کاملComparison of a rapid readout biological indicator for steam sterilization with four conventional biological indicators and five chemical indicators.
OBJECTIVE In this study, we compare a new biological indicator that provides results within 3 hours with four conventional, 48-hour biological indicators and five chemical indicators. DESIGN Biological indicators tested included the conventional Attest 1262, Proof Plus, Assert, and Biosign, and the new Attest 1292 Rapid Readout biological indicator. Chemical indicators tested included Comply,...
متن کاملEffects of temperature and relative humidity on biological indicators used for ethylene oxide sterilization.
A study was made to determine the effects of temperature and moisture on the D-value of a common biological indicator. Relative humidity (RH) was varied between 10 and 70% in increments of 10%, and temperature was varied between 30 and 70 degrees C in increments of 10 degrees C. Temperature was found to have a pronounced effect on the D-value. At 60% RH, the D-value varied from 15.0 min at 30 d...
