Mycobacterium leprae Infection in a Wild Nine-Banded Armadillo, Nuevo León, Mexico

Emerging Infectious Diseases, 2022
Nine-banded armadillos (Dasypus novemcinctus) are naturally infected with Mycobacterium leprae and are implicated in the zoonotic transmission of leprosy in the United States. In Mexico, the existence of such a reservoir remains to be characterized.

Structural Implications of Mutations Conferring Rifampin Resistance in Mycobacterium leprae

Scientific Reports, 2018
The rpoB gene encodes the β subunit of RNA polymerase holoenzyme in Mycobacterium leprae (M. leprae). Missense mutations in the rpoB gene were identified as etiological factors for rifampin resistance in leprosy.

Ticks as potential vectors of Mycobacterium leprae: Use of tick cell lines to culture the bacilli and generate transgenic strains

PLoS Neglected Tropical Diseases, 2018
Leprosy is an infectious disease caused by Mycobacterium leprae and frequently resulting in irreversible deformities and disabilities. Ticks play an important role in infectious disease transmission due to their low host specificity, worldwide ...

PGL I expression in live bacteria allows activation of a CD206/PPARγ cross-talk that may contribute to successful Mycobacterium leprae colonization of peripheral nerves

PLoS Pathogens, 2018
Mycobacterium leprae, an obligate intracellular bacillus, infects Schwann cells (SCs), leading to peripheral nerve damage, the most severe leprosy symptom.

Nontuberculous mycobacterial empyema in an immunocompetent child

Indian Journal of Pathology and Microbiology, 2018
Nontuberculous mycobacterium (NTM) species are mycobacterial species other than those belonging to the Mycobacterium Tuberculosis complex and Mycobacterium leprae. There are very few reports of NTM in immunocompetent children causing empyema.

Mycobacterium leprae-induced nerve damage: direct and indirect mechanisms.

Pathogens and Disease, 2018
Leprosy is a chronic infectious disease caused by Mycobacterium leprae. This disease is characterized by skin and peripheral nerve trunk damage. The mechanisms responsible for the observed nerve damage in leprosy could be directly related to the ability ...

Deciphering the genetic control of gene expression following Mycobacterium leprae antigen stimulation

PLoS Genetics, 2017
Leprosy is a human infectious disease caused by Mycobacterium leprae. A strong host genetic contribution to leprosy susceptibility is well established. However, the modulation of the transcriptional response to infection and the mechanism(s) of disease ...

Coexistence of Scrofuloderma and Lepromatous Leprosy in Reaction: A Case Report

Clinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT Leprosy and tuberculosis (TB) are both chronic granulomatous infections caused by bacilli of the genus Mycobacterium. The simultaneous occurrence of cutaneous tuberculosis and leprosy is rare. We report a 56‐year‐old male presenting with painful erythematous nodules and plaques over the face and extremities for 1 week, along with asymptomatic ...

Salivary anti-PGL-1 IgM may indicate active transmission of Mycobacterium leprae among young people under 16 years of age

Brazilian Journal of Infectious Diseases, 2017
Considering that the main route of Mycobacterium leprae transmission is the upper respiratory tract, detection of salivary antibodies can be a useful tool for diagnosing early infection.
