Update on novel validly published taxa of bacteria isolated from domestic animals described in 2022.

Expansion of our knowledge of the microbial world continues to progress at a rapid rate and carries with it an associated need for recognizing and understanding the implications of those changes. Here, we describe additions of novel taxa from domestic animals published in 2022 that are validly published per the International Code of Nomenclature of Prokaryotes. These included new members of Staphylococcaceae, Moraxella nasovis sp. nov. in sheep with respiratory disease, three additions to Campylobacteraceae (including one from chickens with spotty liver disease), and multiple additions of organisms from the microbiota of dogs, pigs, and especially honeybees and other important pollinators. Noteworthy additions were associated with diseases of cattle, including mastitis, endocarditis, orchitis, and endometritis. Also described in 2022 was Pseudochrobactrum algeriense sp. nov., a member of the Brucellaceae family, isolated from the mammary lymph nodes of cows.
