A method for detecting, identifying and measuring infectious disease causing microorganisms is described. The method utilizes a plural medium arrangement in which a test liquid containing a microorganism is simultaneously introduced. Different media are utilized for the plural medium arrangement and at least one of the media can contain a respiration inhibiting material and/or other reagents such as antibiotics. Dissolved oxygen measurements of the media are taken as a measurement of microorganism respiration. Oxygen electrode signals within different media are compared and differential respiration variation rates are determined and identification signals produced. The identification signal resulting from the multiple respiration rate determinations is compared with known values to identify and measure the microorganism. The drug sensitivity of a microorganism is also judged when at least one of the media contains a drug for which the sensitivity of microorganism is to be determined.

[ What is claimed is:] [1.] A method for identifying a species of microorganism in a test liquid in the presence of non-microorganism cell respiration, comprising:supplying a test liquid containing the species of microorganism such that the test liquid is received simultaneously within a plurality of culture cells containing different culture mediums to form different combinations of test liquid containing the species of microorganism and the different culture mediums wherein each culture cell is provided with an oxygen electrode that contacts the test liquid and produces an output signal indicating the dissolved oxygen quantity within the combinations and wherein at least one of said combinations contains a respiration interfering material;detecting differences in dissolved oxygen quantities in the different combinations within said culture cells with the oxygen electrodes respectively corresponding to said culture cells, and with the differences in dissolved oxygen quantities being due to differences in oxygen consumption by the species of microorganism in the combinations;comparing output signals from said oxygen electrodes,correlating said output signals with stored information andidentifying a species of organism in the test liquid based upon a comparison of said output signals and a correlation of said output signals with stored information.
