[Pyodermia in the metal working industry]

It has been possible to identify pyogenic organisms in the corrosion inhibiting oils of tubes, resulting in pyodermia. Degreasing media with heavy alkaline reaction may result in still further diseases of the skin. The problem can be solved by using tubes not protected against corrosion. A list has been compiled showing pathogenic agents which can be isolated from oils. Under certain conditions cutting oil may prove to be a pool of pathogenic agents.
