The 2021 WHO catalogue of complex mutations associated with drug resistance: A genotypic analysis.

catalogue of mutations to serve as a global standard for interpreting molecular information for drug resistance prediction. Methods: A candidate gene approach was used to identify mutations as associated with ...

Multicentre study on the reproducibility of MALDI-TOF MS for nontuberculous mycobacteria identification.

anonymized and sent out to the 15 participating laboratories. Isolates were identified using MALDI Biotyper (Bruker Daltonics). Up to 1330 MALDI- TOF identifications were collected in the study. A score ≥ 1.6 ...

Strong increase of true and false positive mycobacterial cultures sent to the National Reference Centre in Belgium, 2007 to 2016.

by PCR in the NRC). We reviewed mycobacterial species identified and assessed trends over time of proportions of nontuberculous mycobacteria (NTM) vs complex (MTB c), and false positive cultures vs ...

Time-and-motion tool for the assessment of working time in tuberculosis laboratories: a multicentre study.

justify their resource and personnel needs for the implementation of novel, time-saving, cost-effective technologies, as well as identify areas for improvement. Health Topics:  Tuberculosis Tuberculose ...

A cluster of multidrug-resistant Mycobacterium tuberculosis among patients arriving in Europe from the Horn of Africa: a molecular epidemiological study.

with all isolates two SNP s or fewer apart. 22 (76%) patients reported their travel routes, with clear spatiotemporal overlap between routes. We identified a further 29 MIRU- VNTR-linked cases from the ...

Virulence and immunogenicity of genetically defined human and porcine isolates of M. avium subsp. hominissuis in an experimental mouse infection

(MST) we previously identified 49 different genotypes of Mah among Belgian clinical and porcine isolates, with 5 MST s shared by both hosts. Using experimental intranasal infection of BALB /c mice, we ...

MALDI-TOF for the identification of Mycobacteria and their drug resistance profiles

cultures. In total 88.6% (172/194) of the samples were correctly identified on the species-level using a cut-off score of 1.8 and 91.75% (178/194) using a cut-off of 1.65. All samples of the Mycobacterium ...

WIV-ISP's experiences in the use of MALDI-TOF for the identification of Mycobacteria and their drug resistance profiles

Mycobacteria and their drug resistance profiles. By using an optimized extraction protocol, they successfully identified 88.14 % of 194 Mycobacterial strains at a species-level and 3.09 % at genus-level, using ...
