1 Refers to the number strains in the database with a sequence similarity of ≥ 99% to that of the query sequence.
2 Refers to 100% sequence similarity with N. asteroides, N. asiatica and N. abscessus sequences.
3 99.6% sequence similarity to a single N. bejingensis sequence (GenBank accession no. AY756543) but <99% sequence similarity to other N. bejingensis strains. Since the sequence demonstrated 99.0% similarity to the reference N. arthriditis sequence, it was assigned as such.
4 Refers to 100% sequence similarity with N. farcinica sequences as well as with sequence of N. otitidiscavarium strain DSM 43242T (GenBank accession no. X80611).
