Title:
APPARATUS FOR CULTURING ANTIBIOTICS
Document Type and Number:
Japanese Patent JPS55114284
Kind Code:
A
Abstract:
The apparatus is arranged to receive a transparent plastics tray (1) having rows of cells (4), each containing a mixture of a cultured micro-organism which has been incubated in the presence of an antibiotic under test. The mixture differs from one cell to the next in terms of antibiotic concentration, antibiotic used and/or micro-organism used. The tray is made to advance through the apparatus (e.g. on guides 22 and driven at 23). A parallel beam of light is directed down on each cell to give a spot size just smaller than the base of the cell. The cloudiness of the culture is measured as a function of the ratio between the directly transmitted light (photo-diode 10 Fig. 2) and light which is diffused obliquely to the direct light (photo-diodes 11 and 12). Electronic means are arranged to use the measurement as a pass/fail test for the antibiotic in each cell (clear = pass, cloudy = fail).
