Pauljensenia is a genus of Gram-positive bacteria in the family Actinomycetaceae. It was established in 2018 during a genome-based taxonomic reorganization of the phylum Actinomycetota, and currently contains a single validly published species, Pauljensenia hongkongensis . [1] The genus is named in honor of microbiologist Paul R. Jensen, noted for his contributions to the study of marine actinomycetes.

Taxonomy

The genus Pauljensenia was proposed in 2018 following a large-scale phylogenomic analysis of the class Actinomycetia. The type species, Pauljensenia hongkongensis, had originally been described in 2003 as Actinomyces hongkongensis based on isolates from a patient with pelvic actinomycosis in Hong Kong. [2] Its reassignment was supported by genomic evidence including average nucleotide identity and marker gene phylogeny. [1]

Characteristics

Species within this genus are strictly anaerobic, non-motile, and non-spore-forming rod-shaped bacteria. They stain Gram-positive and grow optimally at mesophilic temperatures around 37°C. The type species was isolated from human blood cultures and abscess material. [2]

Species

Pauljensenia is a monotypic genus, containing only Pauljensenia hongkongensis. [2]
