| Abstract |
This survey covering the period 1967-1972 brought to light 20 cases of tuberculosis among 74 laboratory technicians exclusively engaged in screening tests for TB bacillus, and 29 cases among the total of 379 technicians employed in the 23 laboratories covered by the survey. Analysis of the possible sources of contamination led the authors to suspect the following as being the principal sources of contamination: handling of biological material by pipette and mouth, and various techniques giving rise to the formation of aerosols (Pasteur pipettes, centrifugal machines, crushing and homogenising equipment, etc.). Technical preventive measures: isolation and investigation of mycobacteria in a special room which is disinfected every evening and provided with easily cleaned equipment; daily emission of a disinfecting mist; use of laminar flow enclosures. The efficacy of these methods has been demonstrated by 31/2 years' experience. |
