1472961 Microbiological testing ANALYTAB PRODUCTS Inc 2 April 1974 [10 April 1973 21 March 1974] 14599/74 Heading C6F A profile recognition method of identifying a bacterial specimen involves, in broad outline, performing a series of standard tests in a series of micro-reaction chambers 17, Figs. 1 to 3, mounted on a test plate 11, 21 tests made in 20 chambers, dividing the tests into seven groups of three, allotting to each group a score ranging from 0 to 7 in the following manner: and comparing the seven - digit number obtained with a pre-prepared profile register. Example: 5 044 552 = E. coli. The coder depicted in Figs. 4 and 5 may be used to record the scores. In operation, whenever a positive reaction is to be recorded a pencil, probe or stylus 24 is inserted into an indentation 23a in the slide 23 of the group concerned through the appropriately positioned slot 25, 26 and 27, and the slide is then drawn out by the pencil &c. as far as the slot will allow. In this position the total score for the particular group is visible on the slide through window 28. For verification of the score, the simulated colour patterns on the slides visible through windows 29 can be matched with those obtained on the test strip 11. Aerobic and anaerobic bacteria may be tested. In a further embodiment employing 50 tests e.g. systems designed to determine Enterobacteriaceae or species and strains of Lactobacillus, the scores for each group may be represented by letters or numbers derived from a directory or coder, Fig. 8 (not shown). Example, CB 473 9UA GA = Streptococcus. This coder has five slides representing groups and has slot lengths in the ratio 1:2:4:8:16 per group giving 25 test positions. The other set of five groups is scored by using the coder a second time.
