Taxonomy

Description
Helical cells are rounded to oblong in cross sections, with a diameter of 0.5–0.7µm at the widest point. The length varies between 30 and 80 µm. Approx. 70–80 periplasmic flagella. The rounded protoplasmic cylinder is 0.4–0.5 µm in diameter. Members of this species colonize the hindgut of the genus Incisitermes. They can be detected with the 16S rRNA-targeted oligonucleotide probe It-Hol-183 (5'-CCATGCCACAGCACGATAAG-3'). The type genome is from the hindgut of the termite Incisitermes tabogae.

Includes all genomes that show ≥95% average nucleotide identity (ANI) to the type genome. The type genome has an estimated size of 3.72 Mbp and a GC content of 49.1 mol%.

Submitter comments
 Metrics are estimated from the Prokka prediction. The tRNA identification was done with tRNAscan-SE. Completeness was estimated using CheckM. CheckM2 provides a completeness of  84.7% with 1.3% contamination. Estimating the same genome completeness with BUSCO, using the spirochaetes_odb10 dataset, yields a completeness of 95.8% with 0.4% duplicated genes.
