[Modification of the koch bacillus by a material extracted from tuberculosis lesions].
Lymph node lesions of tuberculous cattle and swine gave, after disruption, centrifugation through 2.2 M sucrose, and ultrafiltration, a material that brings about, in vitro, modification of the tubercle bacilli or chromogenic mycobacteria into bacterial elements that are not acid fast, rapidly growing on nutritive agar supplemented with glycerol. The phenomenon is similar to that which the authors have previously described, using an inducing agent extracted from cultures of mycobacteria, called "endometallaxic conversion."
