- A novel Mycobacterium species, Mycobacterium cajalii sp. nov., is proposed based on strain HUMS_1102779-3 isolated from a patient's sputum.
- Genomic analysis shows it is closely related to Mycobacterium servetii but below species thresholds, with a 6.2 Mb genome, 69.03% GC content, and 5833 coding sequences.
- Phenotypic traits include fast growth, scotochromogenicity, rough yellow-orange colonies, and distinct biochemical and antimicrobial susceptibility patterns compared to M. servetii.
- The type strain is HUMS_1102779-3, deposited as CECT 31296 and DSMZ 120455, with genome accession ASM4580900v1.
