Abstract
The objective: to compare results of species identification of non-tuberculous mycobacteria by PCR (Amplitub-NTM Differentsiatsia) and MALDI-TOF mass spectrometry in clinical samples and mycobacterial cultures.
Subjects and Methods. 40 clinical samples and 110 cultures of non-tuberculous mycobacteria were tested. Two methods were used for testing: Amplitub-NTM Differentsiatsia and MALDI-TOF mass spectrometry.
Results. A high level of agreement between results of MALDI-TOF mass spectrometry and Amplitub-NTMB Differentsiatsia PCR kit was demonstrated. PCR confirmed its high efficiency, detecting non-tuberculous mycobacteria in 89.3% of samples; the final match of species identification with MALDI-TOF in both clinical samples and cultures made 85.1%. Both methods demonstrate a high level of agreement and they complement each other. The PCR kit can be used as the main screening method, especially in TB laboratories. If negative or indeterminate results are obtained, combination with MALDI-TOF or sequencing is recommended The optimal diagnostic strategy involves the use of PCR as a part of comprehensive approach to non-tuberculous mycobacteria identification.
