The reclassification of Streptobacillus hongkongensis as Pseudostreptobacillus hongkongensis gen. nov., comb. nov. is proposed because of the separate phylogenetic position on the basis of the 16S rRNA gene sequence phylogeny, the combined analysis of the three protein-coding housekeeping genes groEL, gyrB and recA and a core genome sequence phylogeny to all other Streptobacillus species that is supported by phenotypic differences. The species Pseudostreptobacillus hongkongensis is the type species of the genus. The type strain is HKU33T, JCM 18691T, NCTC 13659T, DSM 26322T.
Keywords: Pseudostreptobacillus hongkongensis.
