Biomérieux investigation was conducted.Investigational testing included: - vitek® 2 anc id cards (customer lot expired, so two random lots were tested) to check the customer result, - vitek® ms, - api® coryne strip.Results: - vitek® 2 anc id: excellent identification to corynebacterium ulcerans, for both lots tested.- vitek® ms: excellent identification to the species corynebacterium ulcerans.- api® coryne strip: doubtful profile with a possibility of corynebacterium minutissimum.The investigation did not reproduce the vitek® 2 anc id misidentification to the species corynebacterium minutissimum obtained by the customer.The investigation also determined the customer was sub-culturing to a non-recommended media.The customer retested with recommended media (cba) and obtained the correct result.The misidentification appears to be related to the use of non-recommended media by the customer.Based on the results of the investigation, the vitek® 2 anc id is performing as expected.
