Chlorine, Chloramine, Chlorine Dioxide, and Ozone Susceptibility of Mycobacterium avium
**** {M. avium in this paper is called "resistant" to chlorine dioxide, but doesn't appear to be described as "developing resistance" as a result of exposure.} "This study documents the heretofore suspected disinfectant resistance of M. avium... the CT99.9% values of chlorine dioxide and ozone for the M. avium strains were at least 100- and 50-fold greater (respectively) than those for the E. coli strain. In agreement with other studies (4), chlorine dioxide was a better mycobacterial disinfectant than chlorine at equal concentrations."
