PCR-hybridization bead array results for two samples from one patient. Positive results from the patient's admission sample (sample 4) for normalized values were observed for E. aerogenes (probes 18 and 19) and a Pseudomonas sp. (probe 49). Blood culture results for this sample were positive for E. aerogenes, P. putida, and Stenotrophomonas maltophilia (Table 3). Positive results from the patient's post-antibiotic-therapy sample (sample 5) for normalized values were observed for E. aerogenes (probes 18 and 19) and a Pseudomonas sp. (probe 49). Overall mean signal strength is reduced compared to sample 4 results. Blood culture results for this sample were positive for Stenotrophomonas maltophilia (Table 3). Bacterial species corresponding to probe numbers are shown in Table 4. Results are normalized relative to the signal for the negative control (NC).
