  • a Formerly nutritionally deficient streptococci.

  • b One of seven Abiotrophia spp. was identified by 16S rRNA gene sequencing during discrepancy investigations. It had been misidentified phenotypically as a Streptococcus species.

  • c Of 23 isolates, 17 were Acinetobacter spp. not A. baumannii and 10 were phenotypically A. baumannii. The latter were revealed to be A. pittii, A. nosocomialis, A. bereziniae, and A. radioresistens by 16S rRNA gene sequencing.

  • d Other organisms identified during the resolution of discrepancies between BCID and the phenotypic comparator assays included one Pasteurella stomatis isolate (phenotypic ID, E. coli), one Pseudomonas stutzeri isolate (phenotypic ID, P. aeruginosa), one Raoultella planticola isolate (phenotypic ID, K. pneumoniae), and four R. ornithinolytica isolates (phenotypic ID, K. oxytoca).

  • e Although all Staphylococcus spp. are intended to be detected by the panel, these species do not react with either of the Staphylococcus sp. target assays. Several less common Staphylococcus spp. are not detected or are detected with lower sensitivity (18).
