title: [Action of 4 percent sulfuric acid on various species of mycobacteria].
abstract: The action of treatment with 4 p. cent sulphuric acid for 10 minutes, was tested on 13 strains of mycobacteria. Rapidly growing mycobacteria, e.g. M. diernhoferi, M. chelonei M. abscessus, M. Fortuitum, proved much more sensitive than slowly growing mycobacteria, e.g. M. xenopi, M, scrofulacem, M. kansaii, M. avium, M. marinum, BCG, M. tuberculosis and M. Bovis. We observed the persistance of a certain number of viable bacteria in spite of a duration of contact of 120 minutes, Albumin in the culture medium used presented a protective effect together with the high concentration in bacteria.
