This report was initially submitted following notification that a customer france reported a misidentification of bacteroides ovatus (microbiologics atcc® baa-1296) as prevotella disiens in association with the vitek® 2 anc id test kit.There were 3-15 negative (-) well reactions associated with the misidentifications.Biomérieux investigation was conducted.Using the internal reference strain of atcc® baa-1296 as well as the strain submitted by the customer, investigational testing was performed from cultures incubated on cba plates, in anaerobic environment, for two different incubation times (24 and 48 hours).Internal reference strain produced the expected result of bacteroides ovatus for isolates from both incubation times.Customer strain produced expected result of bacteroides ovatus for one test, and produced three (3) discrepant well reactions (+) for the second test.The investigation did not duplicate the customer results, but obtained one time, three (3) discrepant positive (+) well reactions ((b)(4)) with the customer strain, on the random anc id lot (244390210).Anc id test kit lot 244366910 met final qc release criteria.There were no issues observed on qc performance testing.There were no ncmr's written against this lot.Ncmr's were reviewed for the last 13 months and there were no ncmr's written for misidentification of atcc baa-1296 bacteroides ovatus.The investigation concluded the vitek® 2 anc id test kit is performing as intended.
