Hi-plex deep amplicon sequencing for identification, high-resolution genotyping and multidrug resistance prediction of Mycobacterium leprae directly from patient biopsies by using Deeplex Myc-Lep Institute of Tropical Medicine University of Antwerp

Background
Expansion of antimicrobial resistance monitoring and epidemiological surveillance are key components of the WHO strategy towards zero leprosy. The inability to grow Mycobacterium leprae in vitro precludes routine phenotypic drug susceptibility testing, and only limited molecular tests are available. We evaluated a culture-free targeted deep sequencing assay, for mycobacterial identification, genotyping based on 18 canonical SNPs ...

The new phylogeny of the genus Mycobacterium Institute of Tropical Medicine

BACKGROUND: Phylogenetic studies of bacteria have been based so far either on a single gene (usually the 16S rRNA) or on concatenated housekeeping genes. For what concerns the genus Mycobacterium these approaches support the separation of rapidly and slowly growing species and the clustering of most species in well-defined phylogenetic groups. The advent of high-throughput shotgun sequencing leads us to revise conventional taxonomy of ...

Minimally invasive sampling to identify leprosy patients with a high bacterial burden in the Union of the Comoros University of Antwerp Institute of Tropical Medicine

Sofie Marijke Braet, Anouk Van Hooij, Epco Hasker, Erik Fransen, Abdou Wirdane, Abdallah Baco, Saverio Grillone, Nimer Ortuno-Gutierrez, Younoussa Assoumani, Aboubacar Mzembaba, et al.
Author summary Leprosy is the oldest infectious disease known to humankind. We still do not succeed in curbing its transmission, with more than 200,000 new patients detected worldwide each year. Identifying persons with a high burden of bacteria is key to curb transmission. To identify these persons, bacteria are counted in invasive and painful samples like slit skin smears and skin biopsies. We evaluated whether we can use less invasive ...

Genomic characterization of nontuberculous mycobacteria Institute of Tropical Medicine

Tarcisio Fedrizzi, Conor J Meehan, Antonella Grottola, Elisabetta Giacobazzi, Giulia Fregni Serpini, Sara Tagliazucchi, Anna Fabio, Clotilde Bettua, Roberto Bertorelli, Veronica De Sanctis, et al.

Mycobacterium tuberculosis and Mycobacterium leprae have remained, for many years, the primary species of the genus Mycobacterium of clinical and microbiological interest. The other members of the genus, referred to as nontuberculous mycobacteria (NTM), have long been underinvestigated. In the last decades, however, the number of reports linking various NTM species with human diseases has steadily increased and treatment difficulties have ...
