Manufacturer Narrative

A customer from germany reported that he obtained a misidentification of pseudomonas fragi as pseudomonas putida when using api® 20 ne strip (ref.20050/ lot 1008507190).Investigation: review of the complaint database from january 2018 indicated there have been no other complaints reported against this lot for this kind of issue.Review of the batch history record for the customer¿s lot (1008507190) revealed there were no anomalies nor non-conformities noted during the manufacture, quality control, or packaging processes.(b)(4) kits of the batch number 1008507190 were released on 4th february 2021.Retained sample testing: the quality control procedure was performed on the batch 1008507190, by comparison to a reference lot (api 20 ne 25 strips+25 media).The following strains (documented in the instruction for use 07615 l) were tested : aeromonas hydrophila atcc® 35654¿; alcaligenes faecalis ssp faecalis atcc® 35655¿; sphingobacterium multivorum atcc® 35656¿; and pseudomonas aeruginosa atcc® 27853¿.The results obtained with these four strains are compliant to the specifications indicated in the package insert 07615 l.For each strain, there are no differences between the results obtained with the two (2) batches tested.The performance of the lot# 1008507190 is compliant with specifications and consistent with the other lots tested.Conclusion: the species pseudomonas fragi is currently not included in the database api 20 ne, thus it is not possible to identify this species with api 20 ne strips.A study was performed previously to evaluate the possibility to include the species pseudomonas fragi in the api 20 ne database.The outcome of the study indicated it is not possible to update the database with this species.
