To assess if the previously reported Enhydrobacter aerosaccus is, in fact, Moraxella osloensis, we used the following methods: (1) We downloaded 16S sequences of Moraxella osloensis ({"type":"entrez-nucleotide","attrs":{"text":"NR_104936.1","term_id":"559795343","term_text":"NR_104936.1"}}NR_104936.1) and Enhydrobacter aerosaccus ({"type":"entrez-nucleotide","attrs":{"text":"MH715214.1","term_id":"1442633810","term_text":"MH715214.1"}}MH715214.1) from NCBI, the two sequences were aligned by BLASTN (v2.7.1, default parameters except that -evalue 1e-10 outfmt 6 -word_size 16), and found that the similarity between them can reach 99.450%. (2) We aligned the sequences annotated as Enhydrobacter in Greengene [49] with NCBI-NT using BLASTN and found that 78.9% of the sequences were annotated as Moraxella osloensis. (3) Using the same method, we found that 99.4% of the sequences annotated as Enhydrobacter in the MetaPhlAn2 [72] database were annotated as Moraxella osloensis.
