Notification that new names and new combinations have appeared in volume 53, part 6, of the IJSEM

This article is a formal notification of newly published bacterial names and taxonomic combinations that appeared in volume 53, part 6 of the International Journal of Systematic and Evolutionary Microbiology (IJSEM). The document lists 74 newly validated bacterial names, including new species and genera, as well as new taxonomic combinations where previously described organisms have been reclassified. The names are organized according to priority rules based on page number and order of valid publication. Notable entries include new genera such as Soehngenia, Sulfurimonas, Kerstersia, Anaerolinea, and Fulvimarina, along with numerous new species across diverse bacterial groups including Thialkalivibrio, Mycobacterium, Pseudoalteromonas, Vibrio, Achromobacter, and others. Several entries represent transfers of organisms to different genera, such as the reclassification of multiple Sinorhizobium species to the genus Ensifer. This notification serves as an important reference for the microbiology community to track newly recognized bacterial taxa and ensure consistent nomenclature in scientific literature and communication.

Key findings

• 74 new bacterial names and combinations were validly published in IJSEM volume 53, part 6, including new genera and species across diverse bacterial groups
• Multiple notable organisms were reclassified, including transfer of Sinorhizobium species to genus Ensifer and reclassification of Mycobacterium tuberculosis subsp. caprae to Mycobacterium caprae
• Names are listed according to priority rules based on page number and order of valid publication in original articles
• Some entries carry special notes regarding nomenclatural rules, such as Achromobacter denitrificans lacking proper type strain documentation in publicly accessible collections
