An internal biomérieux investigation was initiated due to a low discrimination result with quality control strain clostridium sporogenes atcc 11437 on vitek® 2 v7.01 anc card.The customer tested a strain that is not a biomérieux recommended strain for anc quality control.The expected identification to clostridium sporogenes was confirmed on vitek® ms v3 (kb v3.0).On vitek 2 (v7.01) anc cards, one (1) card of customer lot (cl : 2440223403) and one (1) card of random lot (rl : 2440320203) were tested from cos subculture with anaerobic environment.These tests gave: -low discrimination between cl.Bifermentans and cl group with the cl.-unidentified organism with the rl.Conclusion: the customer result was reproduced in-house on the cl, with low reactivity of the strain: atypical strain.
