Placenta was not available in three of eight cases.
Level of accordance between the final etiology and the most sequencing abundant taxa in the placenta and/or the lung–liver pool. The final etiology was determined based on a combination of diagnostic methods (bacterial culture, histopathology, and 16S rDNA amplicon sequencing–based FISH).
