Results of the 917 bp 16S rRNA gene PCR and the 357 bp 16S rRNA gene PCR from culture-negative samples.

aComprising Escherichia coli (4), E. coli/Shigella spp. (2), Escherichia sp. (1), Enterobacter spp. (9), Ewingella americana (2), Ewingella spp. (3), Klebsiella pneumoniae (1), Salmonella enterica (9), Salmonella spp. (2), Serratia spp. (5), Yersinia spp. (3).
bComprising potential contaminations during sample acquisition, bacteria which might be associated with transient bacteremia, and sequences with too poor quality for identifications even on genus level, i.e., Bacillus sp. (1), Micrococcus sp. (1), Mycobacterium sp. (1), Staphylococcus epidermidis (2), Staphylococcus spp. (4), Streptococcus gallolyticus ssp. pasteurianus (1), non-interpretable results due to poor sequence quality (40).
cComprising Alicycliphilus sp. (1), Alphaproteobacterium (4), Bacillus halodurans (1), Bacterium sp. (1), Balneomonas sp. (1), Bradyrhizobium spp. (5), Caulobacter spp. (26), Cloacibacterium normanense (2), cocci (not further defined) (1), Diaphorobacter spp. (155), Flexibacteriaceae (1), Janibacter sp. (1), Luteimonas sp. (1), multiply superimposing sequences (45), Riemerella sp. (1), Sporichtya sp. (1), Thermonema sp. (1).
dIn addition to this one detection of S. pneumoniae DNA, sodA sequencing identified S. pneumoniae DNA in one additional culture-negative sample, in which 16S rRNA gene sequencing did not allow for an identification even on genus level due to poor sequence quality.
eConfirmed by sodA sequencing.
