[Aerobic flora examination of sputum (author's transl)]

The routine bacteriological test of expectorate, except for mycobacteria, is usually unsatisfactory. There is a need of standardization which results in the present paper from a comparison between the data obtained by two different laboratories on the same samples. It is possible to achieve reasonable and uniform results establishing a uniformity of some procedures, namely; collection of specimens, homogenization, number and type of media, interpretation of data and so on.
