Moreover, based on this identification scheme, in none of the cases did the reference standard (sodA sequence analysis) identify as S.?pneumoniae any isolate included in the study as VGS. Romero et?al. [15] reported a limitation of MALDI-TOF (Bruker) in discriminating the two main S.?gallolyticus subspecies, a finding that differs from our results. We found that five isolates of S.?gallotyticus subsp gallolyticus and six isolates of S.?gallolyticus subsp pasteurianus were correctly identified by MALDI-TOF. However, we also observed that nine isolates of S.?equinus were identified as S.?gallolyticus subsp pasteurianus. Therefore, we suggest that the database of Bruker technology (Biotyper 3.0 software package) should be reviewed to resolve problems associated with identification of S.?equinus and we propose reporting these results as members find more of the S.?bovis group until an appropriate solution has been found. As for the identification scores given by the manufacturer, we assessed the level of agreement in the score interval proposed for identification to genus level (1.7�C1.9). We observed that within this score interval there were 17 concordant results and 11 discrepant results, that is, 60.7% agreement in this interval score (vs. 82.2% in the ��2 interval score). Among these 11 discrepancies, eight S.?mitis were misidentified as S.?pneumoniae. Although Staurosporine mouse this is a limitation of this method, we suggest that VGS isolates identified by MALDI-TOF with scores between 1.7 and 1.9 could be correctly identified. However, if the identification obtained is S.?pneumoniae additional tests should be performed. We also propose the following identification scheme for Transducin VGS isolates from blood cultures. First, MALDI-TOF must be performed in combination with the previously mentioned tests to rule out pneumococci and enable identification of VGS to group level in 94% of isolates with 73% concordance to species level. If the score by this technique is
