title: [Production of L forms of the plague microbe].
abstract: Experiments were conducted in vitro. The process of formation of unstable L-form cultures of Pasteurella pestis under the effect of penicillin was studied. A comparatively high frequency of this phenomenon in various strains was demonstrated. A possible role of the L-transformation process in the persistence of the causative agent in the organism of wild animals in endemic foci of infection is put forward.
