Table 3 Comparison of broad range 16 S rDNA and conventional Bactec blood culture

From: Comparison of broad range 16S rDNA PCR and conventional blood culture for diagnosis of sepsis in the newborn: a case control study

  Number of patients Broad Range 16 S rDNA PCR
Sepsis   Negative Positive
   Bactec + 6# 2* 4
   Bactec - 25 20 5
Not sepsis    
   Bactec + 0 0 0
   Bactec - 17 16 1
  1. # Culture from one patient grew four organisms (Klebsiella spp, Escherichia coli, a viridans Streptococcus and Staphylococcus aureus), culture from another patient grew two organisms (an unnamed viridans Streptococcus and Streptococcus gordomitis). Both had a positive PCR-result and were diagnosed with sepsis based on additional clinical and laboratory findings.
  2. * One of these patients had an inconclusive PCR.
