E.ry.thro.bac.ter. Gr. masc. adj. erythros , red; N.L. masc. n. bacter , rod; N.L. masc. n. Erythrobacter , red rod. Pseudomonadota / Alphaproteobacteria / Sphingomonadales / Erythrobacteraceae / Erythrobacter The genus Erythrobacter belonging to the family Erythrobacteraceae currently consists of fifteen species with validly published names: Erythrobacter alti , Erb. ani , Erb. aurantius , Erb. colymbi , Erb. crassostreae , Erb. cryptus , Erb. dokdonensis , Erb. donghaensis , Erb. insulae , Erb. litoralis , Erb. longus , Erb. neustonensis , Erb. ramosus , Erb. rubeus , and Erb. sanguineus . Historically, Erb. longus Och 101 T was one of the first identified aerobic anoxygenic, photoheterotrophic bacteria. Members of Erythrobacter mainly inhabit various aquatic environments, including seawater, marine mats, freshwater, and hot spring, and could accumulate more biomass for a given amount of organic carbon in luminous than in the nonluminous environments, playing an essential role in the carbon cycle. Cells are Gram‐stain‐negative, and most of the members are motile by flagella. The main respiratory quinone is ubiquinone‐10. The major polar lipids are phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and sphingoglycolipid (SGL). The predominant cellular fatty acids are C 18:1 ω7 c and C 17:1 ω6 c . DNA G + C content (mol%) : 57–67 (by genome sequence or HPLC). Type species : Erythrobacter longus Shiba and Simidu 1982 VP .

Although some nomenclature changes have caused consternation among clinical microbiologists, the discovery of novel taxa and improving classification of existing groups of organisms is exciting and adds to our understanding of microbial pathogenesis. In this mini-review, we present an in-depth summary of novel taxonomic designations and revisions to prokaryotic taxonomy that were published in 2022. Henceforth, these bacteriology taxonomic summaries will appear annually. Several of the novel Gram-positive organisms have been associated with disease, namely, the Corynebacterium kroppenstedtii -like organisms Corynebacterium parakroppenstedtii sp. nov. and Corynebacterium pseudokroppenstedtii sp. nov. A newly described Streptococcus species, Streptococcus toyakuensis sp. nov., is noteworthy for exhibiting multi-drug resistance. Among the novel Gram-negative pathogens, Vibrio paracholerae sp. nov. stands out as an organism associated with diarrhea and sepsis and has probably been co-circulating with pandemic Vibrio cholerae for decades. Many new anaerobic organisms have been described in this past year largely from genetic assessments of gastrointestinal microbiome collections. With respect to revised taxa, as discussed in previous reviews, the genus Bacillus continues to undergo further division into additional genera and reassignment of existing species into them. Reassignment of two subspecies of Fusobacterium nucleatum to species designations ( Fusobacterium animalis sp. nov. and Fusobacterium vincentii sp. nov.) is also noteworthy. As was typical of previous reviews, literature updates for selected clinically relevant organisms discovered between 2017 and 2021 have been included.

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.
