This report was initially submitted following notification from a customer in the united states regarding a misidentification of klebsiella oxytoca as klebsiella pneumoniae in association with the api® 20 e 25 strips (ref (b)(4), lot 1007448620).Api® 20 e identified k.Pneumoniae (low discrimination) and vitek® 2 gn card identified k.Oxytoca (excellent id).An investigation was previously conducted on vitek® 2 which concluded to an identification as klebsiella oxytoca for the patient strain concerned.The lot number of api® 20 e used with the patient strain was communicated after the start of the investigation for the api® 20 e result.Therefore, the retained samples for the impacted lot number (1007448620) the customer reported were not tested.The following two api® 20 e lots (ref.(b)(4), lot number 1007693260, and ref.(b)(4), lot number 1007865190) were used for the investigation to analyze the strain provided by the customer.The strain gave the same identification results on both api® 20 e lots tested.The results obtained were low discrimination between klebsiella pneumoniae ssp pneumoniae 2, klebsiella pneumoniae ssp pneumoniae 1, and pantoea spp 2.The customer¿s identification of k.Pneumoniae ssp pneumoniae (low discrimination) was reproduced internally.Klebsiella oxytoca was not a proposed result.The patient¿s strain shows an atypical result on api® 20 e due to the indole test result that is negative instead of positive.The indole test is intended positive (99%) in the database of api® 20 e for klebsiella oxytoca species.While assessing the risk associated with this case, biomerieux assessed the severity to be negligible.A request to the customer is in progress to have the authorization to keep the customer strain in r&d for a future evolution of the api 20 e knowledge base.A batch record analysis was performed on the impacted lot number 1007448620.No observations or nonconformities were observed during the manufacturing process or the quality control testing.As the investigation did not identify any product performance issue, neither corrective nor preventive actions will be implemented.No other complaints were registered for this issue and no other complaints were registered for the lot number 1007448620.Complaint trend analysis for this reference will continue to be monitored.See section h10.
