[Epidemiological risks of tuberculous infection foci in patients discharging L forms of Mycobacterium tuberculosis].

It is shown that patients from dispensary follow-up groups II, III and VII who discharge M. Tuberculosis L-forms demonstrable after repeated (two) examinations are epidemiologically dangerous to surrounding people. Preventive measures in the families should be based on the duration of the contact with the carrier, social and household conditions, stability and frequency of L-forms isolation. Unstable L-forms are found reversible. In new cases of the above infection from the families at risk the disease runs with scarce symptoms, predominance of respiratory infiltration and solitary destructive lesions, slowly regressive inflammation.
