Different PPD-stimulated cytokine responses from patients infected with genetically distinct Mycobacterium tuberculosis complex lineages

International Journal of Infectious Diseases, 2021
Objectives: The genetic diversity of Mycobacterium tuberculosis complex (MTBC) influences the immune response of the host, which may affect the immunodiagnostic tests and biomarker assessment studies used for tuberculosis (TB).

From 3D to 2D: Harmonization of Protocols for Two-dimensional Cultures on Cell Culture Inserts of Intestinal Organoids from Various Species

Bio-Protocol, 2022
In the expanding field of intestinal organoid research, various protocols for three- and two-dimensional organoid-derived cell cultures exist. Two-dimensional organoid-derived monolayers are used to overcome some limitations of three-dimensional organoid

Electroporation of Mycobacteria [PDF]

Journal of Visualized Experiments, 2008
High efficiency transformation is a major limitation in the study of mycobacteria. The genus Mycobacterium can be difficult to transform; this is mainly caused by the thick and waxy cell wall, but is compounded by the fact that most molecular techniques have been developed for distantly-related species such as Escherichia coli and Bacillus subtilis.

Evolution and spread of a highly drug resistant strain of Mycobacterium tuberculosis in Papua New Guinea

BMC Infectious Diseases, 2022
Background Molecular mechanisms determining the transmission and prevalence of drug resistant tuberculosis (DR-TB) in Papua New Guinea (PNG) are poorly understood. We used genomic and drug susceptibility data to explore the evolutionary history, temporal

Names for mycobacteria. [PDF]

BMJ, 1984
To the founding fathers of bacteriology the nomenclature of pathogens was straightforward. Tuberculosis was caused by the tubercle bacillus and leprosy was caused by the leprosy bacillus and when these pathogens were allocated to the genus Myco bacteriwn this posed no problem, they merely became M tuberculosis and M leprae.

Unique Features of Mycobacterium abscessus Biofilms Formed in Synthetic Cystic Fibrosis Medium

Frontiers in Microbiology, 2021
Characterizing Mycobacterium abscessus complex (MABSC) biofilms under host-relevant conditions is essential to the design of informed therapeutic strategies targeted to this persistent, drug-tolerant, population of extracellular bacilli.

Urine lipoarabinomannan in HIV uninfected, smear negative, symptomatic TB patients: effective sample pretreatment for a sensitive immunoassay and mass spectrometry

Scientific Reports, 2021
Our study sought to determine whether urine lipoarabinomannan (LAM) could be validated in a sample cohort that consisted mainly of HIV uninfected individuals that presented with tuberculosis symptoms.

Import and transmission of Mycobacterium orygis and Mycobacterium africanum, Norway

BMC Infectious Diseases, 2021
Background The aim of the current study was to improve our understanding of the origins and transmission of Mycobacterium africanum (MAF) in Norway. Methods Whole-genome sequences (WGS) were generated for all (n = 29) available clinical isolates received
