Comparison of Two Commercial Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) Systems for Identification of Nontuberculous Mycobacteria

Barbara A. Brown‐Elliott, Thomas R. Fritsche, Brooke J Olson, Sruthi Vasireddy et autres

OBJECTIVES: This multicenter study's aim was to assess the performance of two commercially available matrix-assisted laser desorption/ionization time of flight mass spectrometry systems in identifying a challenge collection of clinically relevant nontuberculous mycobacteria (NTM). METHODS: NTM clinical isolates (n = 244) belonging …

Mycobacterium avium pseudo-outbreak associated with an outpatient bronchoscopy clinic: Lessons for reprocessing

Jessica Seidelman, Richard J. Wallace, Elena Iakhiaeva, Ravikiran Vasireddy et autres

We identified a pseudo-outbreak of Mycobacterium avium in an outpatient bronchoscopy clinic following an increase in clinic procedure volume. We terminated the pseudo-outbreak by increasing the frequency of automated endoscope reprocessors (AER) filter changes from quarterly to monthly. Filter changing schedules should …

Performance of Vitek MS v3.0 for Identification of Mycobacterium Species from Patient Samples by Use of Automated Liquid Medium Systems

E. L. Miller, C. A. Cantrell, Melodie A. Beard, Andrew Derylak et autres

The accuracy and robustness of the Vitek MS v3.0 matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry (MS) system was evaluated by identifying mycobacteria from automated liquid-medium systems using patient samples. This is the first report to demonstrate that proteins within …

Environmental Nontuberculous Mycobacteria in the Hawaiian Islands

Jennifer R. Honda, Nabeeh A. Hasan, Rebecca M. Davidson, Myra D. Williams et autres

Lung disease caused by nontuberculous mycobacteria (NTM) is an emerging infectious disease of global significance. Epidemiologic studies have shown the Hawaiian Islands have the highest prevalence of NTM lung infections in the United States. However, potential environmental reservoirs and species diversity have …

Variable-Number Tandem-Repeat Analysis of Respiratory and Household Water Biofilm Isolates of “Mycobacterium avium subsp. hominissuis” with Establishment of a PCR Database

Elena Iakhiaeva, Susan T. Howard, Barbara A. Brown‐Elliott, Steven G. McNulty et autres

"Mycobacterium aviumsubsp.hominissuis" is an important cause of pulmonary disease. It is acquired from environmental sources, but there is no methodology for large population studies. We evaluated the potential of variable-number tandem-repeat (VNTR) analysis. Clinical and household biofilmM. aviumisolates underwent molecular identification. Testing …

Utility of Sequencing the erm (41) Gene in Isolates of Mycobacterium abscessus subsp. abscessus with Low and Intermediate Clarithromycin MICs

Barbara A. Brown‐Elliott, Sruthi Vasireddy, Ravikiran Vasireddy, Elena Iakhiaeva et autres

The erm(41) gene confers inducible macrolide resistance in Mycobacterium abscessus subsp. abscessus, calling into question the usefulness of macrolides for treating M. abscessus subsp. abscessus infections. With an extended incubation (14 days), isolates with MICs of ≥8 μg/ml are considered macrolide resistant …
