Abstract

During the phylogenetic analysis of the genus Sphingopyxis, we found that an incorrect 16S rRNA gene sequence (accession number: D13727) was provided in the original description of Sphingopyxisterrae NBRC 15098Tand the wrong sequence has been adopted and used for a long time. It should be replaced by the new correct 16S rRNA gene sequence (accession number: MF618306). The new sequence shared the highest similarity (99.8 %) with that of Sphingopyxisummariensis DSM 24316T. The average nucleotide identity (ANI) (96.87 %) and digital DNA-DNA hybridization (75.30 %) values based on the whole-genome sequences and almost the same phenotypic and chemotaxonomic characteristics of the two type strains revealed thatSphingopyxisummariensis should be a later heterotypic synonym ofSphingopyxisterrae. However, the distinctions in the genome size, hydrolysis of aesculin, α-glucosidase and particularly the fatty acid profiles strongly support that strain DSM 24316Tshould be considered to represent a novel subspecies ofSphingopyxisterrae. Two novel subspecies are therefore proposed, namely Sphingopyxisterraesubsp. terrae subsp. nov. (type strain E-1-AT=NBRC 15098T=JCM 10195T=DSM 8831T=LMG 17326T) and Sphingopyxisterraesubsp. ummariensis subsp. n...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
