Abstract
Blood culture, a method for identifying causative agents of bacterial sepsis, requires several days. The combination of cell-direct polymerase chain reaction and nucleic acid lateral flow immunoassay (cdPCR-NALFIA) is a simple and sensitive detection method for identifying pathogenic bacteria. Furthermore, this assay, when applied directly to blood samples yields results within 4.5 h, without requiring culture. This study was performed at five hospitals in Japan between 2013 and 2016. Blood samples from 73 patients with clinically suspected sepsis yielded 18 positive blood cultures, and the isolated bacterial species were detectable using cdPCR-NALFIA in nine samples. Thirteen samples were positive on cdPCR-NALFIA. In total, 17 samples confirmed to have bacterial species were detectable using cdPCR-NALFIA and/or blood culture with a true positive rate of 76.5% and 64.7%, respectively. The combination of blood culture and cdPCR-NALFIA could improve the rate of detection of bacterial sepsis.
