A strain of a novel non-chromogenic mycobacterium was isolated from
synovial tissue from a 68-year-old female with bursitis of her right elbow.
The slowly growing strain had a unique PCR-restriction enzyme analysis
(PRA) profile of the hsp65 gene and 16S rRNA gene sequence in comparison
with other mycobacterium species. The most closely related species, as
determined by 16S rRNA gene sequence analysis, are Mycobacterium malmoense,
Mycobacterium marinum, Mycobacterium ulcerans and members of the
Mycobacterium tuberculosis complex. The HPLC and biochemical profiles
resembled those of Mycobacterium gastri, although differences were noted in
the peak-height ratio of the HPLC pattern and the nitrate and
pyrazinamidase tests. On the basis of PRA, HPLC, biochemical and 16S rRNA
gene sequence analyses, the name Mycobacterium lacus sp. nov. is proposed
for this potential pathogen. The type strain is strain NRCM 00-255(T)
(=ATCC BAA-323(T)=DSM 44577(T)). |
