A phylogenetic tree of keratinolytic bacterial isolates and the closely related genera based on 16S rRNA gene sequence. NCBI accession numbers are shown in parentheses. The tree was generated using neighbor-joining technique, and the evolutionary distances calculated based on the maximum composite likelihood and the bootstrap value was set as 1000 replicates. The tagged bacterial strains represent keratinolytic isolates, and those without tags are reference strains from GenBank. The tree was rooted on Chryseobacterium culicis as an out-group.
