A customer in (b)(6) had notified biomérieux of a misidentification result when testing on two different lots of vitek® 2 gp id cards (2420352403 and 24203301133).Vitek 2 identified the strain as streptococcus gallolyticus ssp pasteruianus.The strain was confirmed as streptococcus pasteuri via 16s rdna sequencing method.An internal biomérieux investigation was performed.The customer did not submit the strain for further evaluation.This organism, streptococcus pasteuri, is not claimed for the vitek 2 gp id test kit.After research by the r&d strain collection department, it was determined that the species streptococcus pasteuri is not recognized by the taxonomy validation committee, so it is absent in lpsn, dsmz.In the ncbi taxonomy, the species is listed but with the comment "unpublished name", only the species s.Pasteurianus is cited.According to these elements, it is considered that there was no misidentification on the vitek 2 gp id card.The vitek 2 gp id cards performs as intended.
