An epidemiological survey to assess the prevalence of pulmonary tuberculosis among Pallavan Bus Transport Corporation Employees in Madras was undertaken. 8581 (47.2%) of the total 18185 employees were screened by Mass Miniature Radiography. Of the 288 raidological suspects (3.4%), 121 workers (1.4%) had active and probably active pulmonary tuberculosis. Prevalence of bacillary cases was found to be 0.12%. there was no significant difference (p>0.2) in the prevalence of sputum positive cases among various categories of workers. The lower prevalence rates in transport employees might be due to their better socio-economic conditions.
