To minimize false positives at this stage of the development of the molecular probe technology, we calculated the average plus five standard deviations. We employed that number as the cut-off between negative and positive for each molecular probe on a Tag4 array. Also to minimize false positives at this stage of the development of the molecular probe technology, we required concordance of the data. A majority (> 50%) of the molecular probes for any given bacterium must have been positive for us to call a bacterium present. There is a potential problem with this procedure that is related
to possible strain variation in genome sequence: i.e., genome sequence variation within the same species. Any given molecular probe could be authentically positive for one strain and authentically negative for another.

(ED211; LBH589 concentration leaving four probes), B. fragilis (ED141; leaving four probes), Bifidobacterium longum (ED611; leaving four probes), and two probes for T. pallidum (ED317 and ED322; leaving three probes). Therefore, the data from these five molecular probes were excluded from the analyses. Two of three probes for Gardnerella vaginalis (ED116 and ED121B) were also positive for all five simulated clinical samples, when there was no G. vaginalis DNA present in any sample. Since we would not call a bacterium present or absent on the basis of one molecular probe, G. vaginalis was excluded from the analyses. What remained for evaluation of the simulated clinical samples Selleck Vistusertib Protirelin were 183 molecular probes representing 39 bacteria. We conducted an analogous process for detecting promiscuous molecular probes within the Tag4 data for the twenty-one clinical samples. Again, to minimize false positives at this stage of the development of the molecular probe technology, we identified molecular probes positive for ten or more (equal to, or greater than, 50%) of the clinical samples (excluding Lactobacillus probes).
We abandoned the data therefrom: two probes for A. baumannii (ED212 and ED213; leaving three probes) were positive for twenty and nineteen samples, respectively; two probes for G. vaginalis (ED116 and ED121B; leaving one probe); two probes for Streptococcus pneumoniae (ED276 and ED277; leaving three probes) were positive for twelve and thirteen samples, respectively; one probe for S. pyogenes (ED413; leaving three probes) was positive for ten samples; and one probe for Fusobacterium nucleatum (ED559; leaving five probes) was positive for seventeen samples. The data from all six Enterobacter probes (leaving none) were excluded. G. vaginalis and Pseudomonas aeruginosa were left with only one molecular probe each. Since we would not make a present/absent determination on the basis of one molecular probe, G. vaginalis and P.
