Early detection of infection, identification of microorganism, and correct choice of antibiotics are critical in the management of sepsis. Quantitative real-time polymerase chain reaction (RT-PCR) has the potential to improve the timeliness, sensitivity, and accuracy of detecting pathogens. In this study we utilize this method to detect the enteric bacterial counts in the blood from patients with systemic inflammatory response syndrome (SIRS) in the emergency department (ED). The universal primers utilized in RT-PCR are specific for 23S ribosomal DNA (rDNA) and wec F gene. The results show that in SIRS patients with positive culture results from specimen collected within 10 days after presenting to ED, and patients surviving for less than 28 days, the serum bacterial DNA load of enteric Gram negative bacilli is higher. In SIRS patients with shock, patients fulfilling both white blood cell counts and respiratory criteria of SIRS, and patients fulfilling both white blood cell counts and respiratory criteria of SIRS with Acute Physiology and Chronic Health Evaluation II score more than 20, the serum bacterial DNA load of enteric Gram negative bacilli and 28-day mortality are both higher. These results suggest that bacterial translocation may happen in patients with SIRS and may be related to higher mortality in patients with SIRS.
