(1) A five-digit octal code number is derived from each set of reactions from which an identification is derived by using a code book.
(2) A 7-digit numerical profile is obtained by an octal coding of the test results.
(3) Results of phage-typing of 22 strains from 16 listeriosis cases, which were isolated during an epidemic outbreak in the district of Magdeburg, showed that most strains were determined by the octal codes 73611, 73615, 73655, 73645.
(4) Isolates are identified by using an octal code and the test kit manual.
(5) Based on the pattern of positive and negative biochemical reactions, a five-digit octal code number is calculated.
(6) A computer-generated identification manual accompanies the product, and for each octal code listed there is a numerical value that represents the unknown isolate's degree of fit to a typical organism (LFR), a second numerical value that represents its separation from other organisms (PNOR), and a verbal description of the quality of identification.
(7) Based on the pattern of positive and negative biochemical test results, a five-digit octal code number is calculated.
(8) Half the MICRO-ID misidentifications occurred when the system identified a Citrobacter diversus as a lysine-negative Escherichia coli; all gave one octal number.
(9) After sorting the octal biocodes from the 169 isolates into groupings using a cluster analysis technique, it was shown by a Chi-square goodness of fit test that isolates of a given species were sorted into the same cluster group at a frequency of at least 99%.
(10) These 58 bp contain sequences showing similarities with the targets of trans-acting factors such as Octal-c and NFkB.
(11) Beyond 6 phages, the binary pattern reporting, unintelligible without correction, is possible with an octal number not exceeding 7 digits for a pattern corresponding to a 21-phage set.
(12) But should the system use more than 5 phages, the advantage offered by the octal code becomes obvious because, without computer, the manual coding for comparing the results of various series is always possible.
(13) Analysis of the 100 isolates identified in duplicate revealed 93% reproducibility of genus and species identification and 62% reproducibility of octal code numbers.
(14) Reactions are converted into a 7-digit octal biocode, relayed via a sensor to the memory module, and compared to biocodes preprogrammed in the memory.
