Proposal to reclassify Leptotrichia goodfellowii into a novel genus as Pseudoleptotrichia goodfellowii gen. nov., comb. nov.

Abstract

The reclassification of Leptotrichia goodfellowii as Pseudoleptotrichia goodfellowii gen. nov., comb. nov. is proposed because of the separate phylogenetic position on the basis of the results of 16S rRNA gene sequence analysis, the genomic differences from all other Leptotrichia species and phenotypic differences from Leptotrichia species. The species Pseudoleptotrichia goodfellowii is the type species of the genus. The type strain is LB 57T, CCUG 32286 T, DSM 19756T.

Oceanivirga miroungae sp. nov., isolated from oral cavity of northern elephant seal (Mirounga angustirostris)

“…The species are mainly capnophilic or anaerobic, especially on first isolation, but many strains subsequently grow aerobically in the presence of CO 2 [2]. Based on comparative analysis of the 16S rRNA genes and the available whole genome sequences, the family currently includes eight genera: Leptotrichia, Pseudoleptotrichia, Caviibacter, Oceanivirga, Sebaldella, Sneathia, Streptobacillus and Pseudostreptobacillus [1,3,4]. The Leptotrichiaceae species typically colonize the human or animal oropharynx, respiratory, urogenital and gastrointestinal tracts [1,2,5].…”
