Viable bacteria were found in six bottles of dimethyl sulfoxide (DMSO) at a concentration of approximately one bacterium per 4.4 mL. The 18 bacterial isolates appeared to be tolerating the DMSO rather than metabolizing it. No fungi were detected. DMSO must be assumed to be nonsterile unless it has been previously sterilized.
