Complete genome sequence of Cryptobacterium curtum type strain (12-3)

Area of Science:

• Microbiology
• Genomics
• Phylogenetics

Background:

• Cryptobacterium curtum is the type species of its genus and is phylogenetically distant within the Coriobacteriaceae family.
• This asaccharolytic, opportunistic pathogen is commonly found in the oral cavity and linked to dental infections like periodontitis.

Purpose of the Study:

• To describe the features of Cryptobacterium curtum.
• To present the first complete genome sequence and annotation for an actinobacterial family Coriobacteriaceae member.

Main Methods:

• Whole-genome sequencing of Cryptobacterium curtum.
• Bioinformatic analysis for genome annotation.

Main Results:

• The complete genome sequence of Cryptobacterium curtum was determined to be 1,617,804 bp.
• The genome contains a single replicon with 1364 protein-coding and 58 RNA genes.
• This represents the first complete genome sequence for the Coriobacteriaceae family.

Conclusions:

• The genome sequence provides valuable insights into the biology and evolutionary placement of Cryptobacterium curtum.
• This work contributes to the Genomic Encyclopedia of Bacteria and Archaea project, expanding genomic resources for underrepresented bacterial groups.
