Sterilization of Mycobacterium tuberculosis Erdman samples by antimicrobial fixation in a biosafety level 3 laboratory

J Clin Microbiol. 2001 Feb;39(2):769-71. doi: 10.1128/JCM.39.2.769-771.2001.

Abstract

Incomplete sterilization of Mycobacterium tuberculosis Erdman cultures followed 1 h of incubation in low concentrations of glutaraldehyde (0.5 and 1.0%) or azide. In contrast, 2.5% glutaraldehyde, paraformaldehyde (2 or 4%), Vesphine IIse or 5% formalin sterilized these samples after 1 h. These results suggest caution in removing fixed M. tuberculosis samples from biosafety level 3.
