NOTE: Isolates were subjected to renewed species determination using matrix-assisted laser desorption ionization time-of-flight mass spectrometry with exceptions as stated below.
aThree C striatum were not obtained for species redetermination.
bOne case had findings of coagulase negative staphylococci (CoNS) and C jeikeium in 2 separate blood cultures, and the isolate was not obtained for species redetermination.
cTwo C coyleae isolates were not obtained for species redetermination.
dOne of the C propinquum isolates was not available for species redetermination.
eThree isolates of Corynebacterium spp were not obtained for species redetermination. All the latter isolates (n = 10) mentioned were species determined according to routine protocol at respectively department of microbiology during the episode of IE.
