Isolation of the newly described species Mycobacterium celatum from AIDS patients

J Clin Microbiol. 1995 Jan;33(1):137-40. doi: 10.1128/jcm.33.1.137-140.1995.


Mycobacterium celatum is a recently described species which, on the basis of conventional tests, may be misidentified as Mycobacterium xenopi or as belonging to the Mycobacterium avium complex. Only genomic sequencing or high-performance liquid chromatography of cell wall mycolic acids can presently allow a correct identification of this mycobacterium. Two cases of infection due to M. celatum, in AIDS patients, are described here. The quantitative susceptibility pattern of the isolates to a wide spectrum of drugs is also reported.
