Abstract:

We characterize three respiratory isolates of the recently described species Mycobacterium talmoniae recovered in Texas, Louisiana, and Massachusetts, including the first case of disease in a patient with underlying cystic fibrosis. The three isolates had a 100% match to M. talmoniae NE-TNMC-100812T by complete 16S rRNA, rpoB region V, and hsp65 gene sequencing. Core genomic comparisons between one isolate and the type strain revealed an average nucleotide identity of 99.8%. The isolates were susceptible to clarithromycin, amikacin, and rifabutin, while resistance was observed for tetracyclines, ciprofloxacin, and linezolid. M. talmoniae should be added to the list of potential pulmonary pathogens, including in the setting of cystic fibrosis.
