摘要

A mouth in the upper edge of Petri dish (1) proper is covered with at least one sheet (2) and at least one small aperture (4) is provided on the bottom (3) of said Petri dish (1). Partitions (8) may be installed between the bottom (3) of the Petri dish (1) and the sheet (2), and a sealing lid (6) fitted in the small aperture (4).
The method of the present invention, using the fractionized Petri dish (1) possessing the pervious sheet (2) as the cultivation surface, assorts the media different in kind from each other, the media being different from each other in the kind of the contained drug or the media containing drugs which are same in kind but different from each other in the concentration in each fraction, into which the bacteria are inoculated.
