An internal biomérieux investigation was performed.The investigation was initiated due to a misidentification of bergeyella zoohelcum on eeq survey (ctcb survey qc strain ctcb 164-1642), as myroides spp.Ctcb information: identification to the species for 63.4% of participants and to the genus for 64.4%.The isolate was subcultured on columbia blood agar medium, and testing included vitek® 2 gn cards from the customer lot (cl:241389540) & random lot (rl: 241379810).The results were compared with sequencing full 16s used to determine the intended result.The reference method confirmed the identification to the species bergeyella zoohelcum.On vitek® 2, multiple lots of gn cards gave a low discrimination call of myroides spp/ brevundimonas diminuta/vesicularis.The misidentification to the species myroides spp obtained by the customer (low discrimination in house) was not reproduced.Bergeyella zoohelcum is not in the vitek® 2 knowledge base (kb) and there is a limitation for species not claimed in the kb: testing of unclaimed species may result in an unidentified result or a misidentification.
