Abstract

We examined American Type Culture Collection (ATCC) strains of and by using multilocus DNA target sequencing. Apart from the type strain, all 10 ATCC strains examined were classified incorrectly, with most being reclassified as belonging to the ’ relatedness group. All four strains were tightly clustered, but heterogeneity was observed within the cluster. As a result of the incorrect annotation of the strains, two commonly used methods of identification are compromised and two case reports implicating as a human pathogen are probably incorrect, with the isolates probably belonging to the ’ relatedness group. These findings together with a review of isolates identified at two large reference laboratories suggest that is not a clinically significant isolate.
