121 Main St. Lebanon NJ. Eight to 10 mL of blood from consenting healthy donors were collected into a BACTEC Plus + Aerobic/F bottle BD, Franklin Lakes, NJ). This blood check details culture was then spiked with 5 to 50 CFU of either S. aureus (MSSA or MRSA) or E. coli bacteria. The blood culture bottle was incubated in a BD BACTEC 9050 incubator and grown until the culture is called positive. Once positive, the bacteria were harvested with a Serum Separation Tube (SST)

(BD, Franklin Lakes, NJ) as described elsewhere [19, 20]. Briefly, the tube was spun for 10 minutes at 2000×g and the supernatant was removed. A sterile, rayon-tipped swab applicator (BD, Franklin Lakes, NJ) was used to harvest the bacteria from the gel layer of the tube and this was suspended into a 0.9% saline solution. click here From this point forward, these SST preparations were handled the same as described for pure cultures, except time points were only taken VX-680 order at four and six hours of incubation. Comparison of molecular

AST results to the marcobroth “gold standard” method results The macrobroth method results are considered the “gold standard” results because they are performed based on the currently accepted method as indicated by CLSI documentation. Differences between the molecular AST results and the gold standard results are defined as follows: 1) an error is called minor when the molecular AST indicates susceptibility and the macrobroth AST indicates intermediate resistance, 2) an error is called major when the molecular AST indicates resistance and

the macrobroth AST indicates susceptibility, and 3) an error is called very major when the molecular AST indicates susceptibility and the macrobroth method indicates resistance [12]. Additional data sets Additional data sets are provided which detail all the cycle time DCLK1 data used to produce figure and data found within this manuscript. The file in which these data can be found is called Supplemental Data to manuscript.doc. Within this file is Additional file 1: Table S1 and Additional file 1: Table S2. Additional file 1: Table S1, ETGA and gsPCR Ct Data of AST Experiments from Pure Cultures, provides data used for Figures 2, 3, and 4 and pure culture data in Table 1. Additional file 1: Table S2, ETGA and gsPCR Ct Data of AST Experiments from Cultures Harvested from Positive Blood Cultures, provides data for the AST experiments from bacteria harvested from blood culture found in Table 1. Figure 2 Methicllin sensitive Staphylococcus aureus against oxacillin and vancomycin AST results. The visual results of the macrobroth dilution standard method is shown on the left (A and D), along with the time course results of the ETGA (B and E) and gsPCR (C and F) AST analyses, plotting Ct versus time. Vertical, dashed lines indicate when aliquots were removed for analysis. Since Ct values are inversely related to signal strength, the y-axes are inverted to visually demonstrate a rise in signal over time.
