Blood was collected at various times for assessment of (i) bacteremia via simple blood culture; (ii) numbers of bacteria (CFU per milliliter) via quantitative culture; (iii) presence of γDPGA in blood and serum; (iv) hematology for blood cell count, neutrophil counts, and lymphocyte counts; and (v) clinical chemistry to monitor aspartate aminotransferase, lactate dehydrogenase, and C-reactive protein. Here, CRP is linked to bacterial infectious disease with sepsis.
