Mycobacterium talmoniae, a Potential Pulmonary Pathogen Isolated from Multiple Patients with Bronchiectasis in the United States, Including the First Case of Clinical Disease in a Patient with Cystic Fibrosis. J Clin Microbiol 2019; 57:JCM.00906-18. [PMID: 30429252 DOI: 10.1128/jcm.00906-18] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 11/01/2018] [Indexed: 11/20/2022] Open
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.

Abstract
A previously undescribed, rapidly growing, scotochromogenic species of the genus Mycobacterium (represented by strains PB739T and GK) was isolated from two clinical sources - the sputum of a 76-year-old patient with severe chronic obstructive pulmonary disease, history of tuberculosis exposure and Mycobacterium avium complex isolated years prior; and the blood of a 15-year-old male with B-cell acute lymphoblastic leukaemia status post bone marrow transplant. The isolates grew as dark orange colonies at 25-37 °C after 5 days, sharing features in common with other closely related species. Analysis of the complete 16S rRNA gene sequence (1492 bp) of strain PB739T demonstrated that the isolate shared 98.8 % relatedness with Mycobacterium wolinskyi. Partial 429 bp hsp65 and 744 bp rpoB region V sequence analyses revealed that the sequences of the novel isolate shared 94.8 and 92.1 % similarity with those of Mycobacterium neoaurum and Mycobacterium aurum, respectively. Biochemical profiling, antimicrobial susceptibility testing, HPLC/gas-liquid chromatography analyses and multilocus sequence typing support the taxonomic status of these isolates (PB739T and GK) as representatives of a novel species. Both isolates were susceptible to the Clinical and Laboratory Standards Institute recommended antimicrobials for susceptibility testing of rapidly growing mycobacteria including amikacin, ciprofloxacin, moxifloxacin, doxycycline/minocycline, imipenem, linezolid, clarithromycin and trimethropin/sulfamethoxazole. Both isolates PB739T and GK showed intermediate susceptibility to cefoxitin. We propose the name Mycobacterium grossiae sp. nov. for this novel species and have deposited the type strain in the DSMZ and CIP culture collections. The type strain is PB739T (=DSM 104744T=CIP 111318T).

Abstract
Mycobacterium heraklionense sp. nov. (M. heraklionense) is a novel non-tuberculous mycobacterium belonging to the Mycobacterium terrae complex that has recently been described. It has a world-wide distribution. Recently, a case of tenosynovitis in an immunocompetent individual caused by M. heraklionense was reported, indicating that it has the ability to cause diseases. In the present study, in order to provide a more detailed profile of this mycobacterium and to obtain a more complete overall picture of its clinical significance, we report all available data regarding the initial 12 cases of its isolation. Of the 12 patients, 5 (42%) eventually died within a period of 3 months following the isolation of the mycobacterium. However, any connection between the presence of M. heraklionense and these deaths could not be documented. These 5 patients were all males with a mean age of 74.6 years suffering from serious underlying diseases, which most probably were the cause of death. Additional data from possible new cases of M. heraklionense isolation are anticipated.
