Valid and accepted novel bacterial taxa isolated from non-domestic animals and taxonomic revisions published in 2023.

Continued investigation into the bacteria associated with non-domestic animals provides important information for recognizing normal flora, assessing the health status of these unique species of animals, and identifying new or emerging pathogens of concern. In this summary of novel taxa and taxonomic revisions, considerable additions have been made toward understanding fecal and mucosal flora in multiple wild animal species. In addition, novel pathogenic bacteria are discussed, including multiple Chlamydia spp. causing disease in a hawk and crocodile, two Corynebacterium spp. causing oral lesions in penguins and a lesser-known genus, Mergibacter within Family Pasteurellaceae, causing disease in multiple wild bird species. Finally, a few revisions to bacteria isolated from normal non-domestic animal body sites are mentioned.
