Concordance of detected microorganism between PCR and culture based methods.

<p>Venn diagram showing the number of microorganisms found in the PCR, the concomitant blood culture, and the microbiological specimens from the presumed site of infection. Numbers in the overlapping areas reflect microorganisms detected with more than one technique simultaneously. Most of the pathogens were not confirmed with any other technique. Unconfirmed results from the culture based methods are partly not on the PCR target list. Results where the same pathogen was detected more than once in the same specimen were removed from this diagram.
