“…The Kingella genus includes five taxa: K. potus, K. oralis, K. denitrificans, K. negevensis, and K. kingae (21)(22)(23)(24)(25)(26)(27). Recently, two novel species have been proposed, namely K. bonacorsii and K. pumchi (28,29). All of the Kingella species are typically associated with the oral or oropharyngeal microbiome, a common niche for other Neisseriaceae.…”

Taxonomic classification of theNeisseriaceaefamily has focused primarily on the pathogensNeisseria meningitidisandNeisseria gonorrhoeae. As a consequence, the commensalNeisseriaspecies and otherNeisseriaceaegenera such asKingellahave been only loosely classified, resulting in several polyphyletic genera. In this study, using available 16S rRNA sequences and a phylogenetic approach, we found that the genusKingellais polyphyletic, due to misclassification ofKingella potus. Calculation of multiple genome relatedness indices revealed thatK. potusis more similar toNeisseria bacilliformisthan it is to otherKingellaspecies. To better understand the evolution of this clade, we examined the core genome ofKingellaand closely related genera and discovered that the related generaSimonsiellaandAlysiellaform a distinct clade within the genusKingellathat is closely related to the pathogensK. kingaeandK. negevensis. Based on these analyses, we propose incorporation ofSimonsiellaandAlysiellaspecies into the genusKingella.

Taxonomic classification and phylogenetic analysis of the Neisseriaceae family have focused on the pathogens Neisseria meningitidis and Neisseria gonorrhoeae . Less is known about the relationships of commensal Neisseria species and other Neisseriaceae genera, raising the possibility that the phylogeny of this family may not agree with current taxonomy. In this study, we used available nucleotide sequences and a phylogenetic approach to assess the Kingella genus and its relatives. We found that this genus is both paraphyletic and polyphyletic. Kingella potus is more closely related to Neisseria bacilliformis than to other Kingella species. The Alysiella and Simonsiella genera form a distinct clade within the Kingella genus that is closely related to the pathogens K. kingae and K. negevensis . We find a phylogenetic relationship between Conchiformibius , Alysiella , Simonsiella , and Kingella , which we name the CASK clade. Finally, we define the gene sets that differentiate each genus of the CASK clade from one another and from the rest of the Neisseriaceae family. IMPORTANCE Understanding the evolutionary relationships between the species in the Neisseriaceae family has been a persistent challenge in bacterial systematics due to high recombination rates in these species. Previous studies of this family have focused on Neisseria meningitidis and N. gonorrhoeae . However, previously understudied Neisseriaceae species are gaining new attention, with Kingella kingae now recognized as a common human pathogen and with Alysiella and Simonsiella being unique in the bacterial world as multicellular organisms. A better understanding of the genomic evolution of the Neisseriaceae can lead to the identification of specific genes and traits that underlie the remarkable diversity of this family.
