Cultivation of Mycobacterium Leprae

Experimental Biology and Medicine, 1933
McKinley and Soule1 reported the successful cultivation of Mycobacterium leprae, obtained from Puerto Rican lepers, on several culture media. Subsequent reports were made by Soule and McKinley2, 3 when their nonchromogenic strain of acid-fast bacilli, believed to be the true Mycobacterium leprae, had been carried through the eighth and sixteenth ...

Lipid regulation of adenylyl cyclase Rv1625c from Mycobacterium tuberculosis by its membrane‐domain receptor

The FEBS Journal, EarlyView.
The adenylyl cyclase (AC) Rv1625c from M. tuberculosis is a monomeric progenitor of the nine pseudoheterodimeric mammalian AC isoforms. The hexahelical membrane anchor of Rv1625c serves as an inhibitory receptor for fatty acids, particularly oleic acid. One ligand binds into each monomer of the active Rv1625c dimer.

Development and validation of a multiplex real-time qPCR assay using GMP-grade reagents for leprosy diagnosis.

PLoS Neglected Tropical Diseases, 2022
Leprosy is a chronic dermato-neurological disease caused by Mycobacterium leprae, an obligate intracellular bacterium. Timely detection is a challenge in leprosy diagnosis, relying on clinical examination and trained health professionals.

From leprosy to ground zero: Imagining futures in a world of elimination

Medical Anthropology Quarterly, EarlyView.
Abstract Achieving a target of zero—zero disease, zero disability, and zero discrimination—has become the dominant focus of campaigns to control or eliminate diseases, from HIV/AIDS to malaria to leprosy. Given the historical failure of most eradication programs over the last century, such teleological imaginings of disease‐free futures might seem ...

Weight Loss‐Associated Remodeling of Adipose Tissue Immunometabolism

Obesity Reviews, EarlyView.
ABSTRACT Obesity is a multifactorial condition characterized by excessive adiposity and systemic chronic low‐grade inflammation. Recent literature reflects a growing appreciation for the complex interplay between metabolism and the immune system in the pathogenesis of obesity‐related health conditions.

Phylogenomics and antimicrobial resistance of the leprosy bacillus Mycobacterium leprae

Nature Communications, 2018
Leprosy is caused by the yet-uncultured pathogen Mycobacterium leprae. Here, Benjak et al. obtain M. leprae genome sequences from DNA extracted from patients' skin biopsies and, by analysing 154 genomes from 25 countries, provide insight into the ...

M. leprae inhibits apoptosis in THP-1 cells by downregulation of Bad and Bak and upregulation of Mcl-1 gene expression

BMC Microbiology, 2006
Background Virulent Mycobacterium leprae interfere with host defense mechanisms such as cytokine activation and apoptosis. The mitochondrial pathway of apoptosis is regulated by the Bcl-2 family of proteins.

Leprosy in blood donors

Tropical Medicine &International Health, EarlyView.
Abstract Objectives We investigated the prevalence of anti‐phenolic glycolipid‐I (PGL‐I) IgM antibodies among temporarily unfit blood donors at the Pará State Blood Bank (HEMOPA), located in the Amazon region of northern Brazil. Using an arbitrary high cutoff for optical density (OD ≥0.750) in ELISA, a subset of donors was invited for clinical ...

A Mycobacterium leprae VNTR database [PDF]

Leprosy Review, 2010
A great deal of the last quarter of a century’s astonishing progress in understanding and treating human disease is attributable to the existence of public databases where information about DNA sequences, protein sequences, protein structures, human variation, etc. is stored and is freely available to all interested investigators.

Metagenomics of Imported Multidrug-Resistant Mycobacterium leprae, Saudi Arabia, 2017

Emerging Infectious Diseases, 2020
Using shotgun metagenomics, we identified an imported case of multidrug-resistant Mycobacterium leprae in a Filipino resident of Saudi Arabia in 2017. We determined the phylogenomic lineage (3K1) and identified mutations in rpoB and rrs corresponding to ...
