An Unnamed Human Oral Bergeyella sp. as the Cause of an Unusual Bacterial Keratitis

Figure 2

The phylogenetic tree includes 27 sequences representing the most closely related records in the Nucleotide database of the National Center for Bioinformatics, including all established Bergeyella spp. The patient sequence (highlighted, bold) forms a high-confidence clade (93% bootstrap) with unnamed human oral Bergeyella spp. and is quite distant from B. zoohelcum, B. porcorum, and B. cardium. Tree generated from the alignment of trimmed 16S ribosomal ribonucleic acid gene records and generated in IQ-Tree with generalized midpoint optimization and bootstrap branch support of 1000 ultrafast replicates; scale is substitutions per site.
