Mycobacterium abscessus virulence traits unraveled by transcriptomic profiling in amoeba and macrophages.

Université Paris-Saclay, UVSQ, Inserm, Infection et inflammation, Montigny-Le-Bretonneux, France.

Free-living amoebae are thought to represent an environmental niche in which amoeba-resistant bacteria may evolve towards pathogenicity. To get more insights into factors playing a role for adaptation to intracellular life, we characterized the transcriptomic activities of the emerging pathogen Mycobacterium abscessus in amoeba and murine macrophages (Mϕ) and compared them with the intra-amoebal transcriptome of the closely related, but less pathogenic Mycobacterium chelonae. Data on up-regulated genes in amoeba point to proteins that allow M. Read More

Jaime Esteban, Dept. Of Clinical Microbiology. IIS-Fundación Jiménez Díaz. Av. Reyes Católicos 2. 28040-Madrid (Spain).

Objective: Non-pigmented rapidly growing mycobacteria (NPRGM) are a group of organisms of increasing interest due to the growing number of potential patients and the difficulties for a proper treatment in many of them. However, the evolution of these diseases in a long period of time and its evolutionary changes has been described only in a scanty number of reports.

Methods: We performed a retrospective study between January 1st 2004 and December 31st 2017 in order to evaluate the clinical significance and types of diseases caused by NPRGM. Read More

Transmission of Mycobacterium chelonae and Mycobacterium marinum in laboratory zebrafish through live feeds.

J Fish Dis 2019 Oct 16;42(10):1425-1431. Epub 2019 Aug 16.

Department of Environment and Forest Biology, State University of New York College of Environmental Science and Forestry, Syracuse, New York.

The zebrafish (Danio rerio) is a popular vertebrate model organism used in a wide range of research fields. Mycobacteriosis, caused by Mycobacterium species, is particularly concerning because it is a common disease associated with chronic infections in these fish. Infections are also a source of uncontrolled experimental variance that may influence research results. Read More

Histopathological Features of Mycobacterium chelonae Infection in Two Farmed Japanese Pufferfish (Takifugu rubripes).

J Comp Pathol 2019 Jul 13;170:86-90. Epub 2019 Jul 13.

Faculty of Veterinary Medicine, Okayama University of Science, Ehime, Japan. Electronic address:

Granulomatous lesions were observed in the swim bladder, kidney, spleen and gills of two farmed Japanese pufferfish (Takifugu rubripes) infected with Mycobacterium chelonae. Three types of lesions were noted: unencapsulated clusters of epithelioid cells without central necrosis (type 1), encapsulated granulomas without central necrosis (type 2) and encapsulated granulomas with central necrosis (type 3). Type 3 lesions occurred most frequently in the swim bladder, while type 1 and type 2 lesions occurred frequently in the kidney and spleen, and the gills exhibited mostly type 1 lesions. Read More

Emerging Bacterial Pathogens Unit, IRCCS San Raffaele Scientific Institute, Milano, Italy.

The aim of this study was to clarify the taxonomic status of named species within the genus Mycobacterium. The analysis of genomes belonging to 174 taxa (species or subspecies) of the genus Mycobacterium was conducted using both the Average Nucleotide Identity and the Genome to Genome Distance. A number of synonymous taxa were detected. Read More

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

Am J Clin Pathol 2019 09;152(4):527-536

Massachusetts General Hospital, Boston.

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 to 23 species/subspecies were identified by gene sequencing and analyzed using Bruker Biotyper with Mycobacterial Library v5.0. Read More

Rifamycin derivatives active against pathogenic rapidly-growing mycobacteria.

Bioorg Med Chem Lett 2019 08 2;29(16):2112-2115. Epub 2019 Jul 2.

National and WHO Supranational Reference Laboratory for Mycobacteria, Research Center Borstel, Leibniz Lung Center, Borstel, Germany; University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Infections due to rapidly growing mycobacteria (RGM), and in particular the RGM species Mycobacterium abscessus (Mab), are very difficult to treat and reports on novel therapeutic options are scarce. A hallmark of all pathogenic RGM species is their resistance to the four first-line drugs used to treat infections with Mycobacterium tuberculosis including rifampicin. This study demonstrates that modification of the rifampicin scaffold can restore rifampicin activity against the three most commonly isolated pathogenic RGM species including Mab. Read More

Laboratory diagnosis of nontuberculous mycobacteria in a Belgium Hospital.

Int J Mycobacteriol 2019 Apr-Jun;8(2):157-161

Department of Microbiology, Université Catholique de Louvain, Cliniques Universitaires Saint-Luc, Brussels, Belgium.

Background: Nontuberculous mycobacteria (NTM) have been identified in human pulmonary and extrapulmonary infections and are increasing globally, which makes it challenging to identify them. This article reports our experience with the laboratory identification of NTM in clinical practice among pulmonary and extrapulmonary samples received in our routine work.

Methods: The study was conducted at the Université Catholique de Louvain at the Cliniques Universitaires Saint-Luc, Brussels, Belgium, from 2015 to 2018. Read More
