Mycobacterium lepromatosis is a newly discovered leprosy-causing organism. Preliminary phylogenetic analysis of its 16S rRNA gene and a few other gene segments revealed significant divergence from Mycobacterium leprae, a well-known cause of leprosy, that justifies the status of M. lepromatosis as a new species. In this study we analyzed the sequences of 20 genes and pseudogenes (22,814 nucleoti...
Serological relatedness of ribosomes from microorganisms of the Mycobacterium, Nocardia, and Corynebacterium genera has been analyzed by the microplate immunodiffusion technique. Mycobacterium and Nocardia proved homogeneous and closely related taxa, whereas Corynebacterium was found to be a heterogeneous phylum connected by remote links to the others. The taxonomic position of "diphtheroid mic...
The serological activities of the specific phenolic glycolipid I from Mycobacterium leprae, its dissected parts, and related glycolipids from other mycobacteria were examined by enzyme-linked immunosorbent assay against hyperimmune anti-M. leprae rabbit antiserum and sera from patients with leprosy and other mycobacterial diseases. High anti-phenolic glycolipid I immunoglobulin M antibodies wer...
The integrated map of the Mycobacterium leprae genome unveiled for the first time the genomic organization of this obligate intracellular parasite. Selected cosmid clones, isolated from a genomic library created in the cosmid vector Lorist6, were identified as representing nearly the complete genome and were subsequently used in the M. leprae genome sequencing project. Now a new version of the ...
Leprosy diagnosis is based mainly on clinical manifestations and no laboratory test is available to diagnose asymptomatic disease or to predict disease progression among exposed individuals. Novel comparative genomic in silico analyses and molecular biology tools have discovered unique Mycobacterium leprae proteins with potential diagnostic application. Tuberculoid paucibacillary leprosy (PB) s...
UNLABELLED Mycobacterium leprae induces the formation of lipid droplets, which are recruited to pathogen-containing phagosomes in infected macrophages and Schwann cells. Cholesterol is among the lipids with increased abundance in M. leprae-infected cells, and intracellular survival relies on cholesterol accumulation. The present study investigated the capacity of M. leprae to acquire and metabo...
The nucleotide sequence of 1.5 Mb of genomic DNA from Mycobacterium leprae was determined using computer-assisted multiplex sequencing technology. This brings the 2.8-Mb M. leprae genome sequence to approximately 66% completion. The sequences, derived from 43 recombinant cosmids, contain 1046 putative protein-coding genes, 44 repetitive regions, 3 tRNAs, and 15 tRNAs. The gene density of one pe...
