[Radiophotographic and simultaneous bacteriological detection in an industrial group]

After carrying out a complex investigation of the workers of a confections factory the authors detected 2 new cases of tuberculosis (0,5 0/00), with the aid of radiophotography and another 2 cases (3,4 per 1000 subjects examined) by bacteriological investigation of the subjects that coughed. These last 2 cases were detected between those that had a normal thoracic aspect on the radiophotographic film alone. The observation of the authors allows to conclude that a bacteriological investigation of the suspects following radiophotography is not sufficient and that this type of investigation should be extended to certain groups of the population that show broncho-pulmonary symptoms. The association of the two methods, in well-defined technical and organisational conditions will allow for a significant increase of the efficiency of systematic examinations for the detection of pulmonary tuberculosis.
