Background And Methods: While leprosy primarily affects adults, childhood leprosy poses unique challenges because of its potential to cause lifelong disabilities and stigma. This is a retrospective record review of all patients aged 15 or below, diagnosed with leprosy, who were registered at the leprosy clinic of our tertiary care center from June 2014 to December 2023.

Results: As per hospital records, 1083 leprosy cases were registered at our center during the study period.

Mycobacterium tuberculosis causes human tuberculosis. As mycobacteria are protected by thick lipid cell wall, humans have developed immune responses against diverse mycobacterial lipids. Most of these immunostimulatory lipids are known as adjuvants acting through innate immune receptors, such as C-type lectin receptors.

Background & objectives Although multi-drug therapy has decreased the burden of disease, leprosy is yet to be eliminated. Accelerating progress requires optimal use of existing tools, advanced diagnostic tests, newer drugs, and vaccines. The search for a vaccine with therapeutic and preventive potential is ongoing, but evidence on effectiveness and safety is lacking.

Background: Detection of infection with Mycobacterium leprae allows timely prophylactic treatment, thereby reducing transmission as well as the risk of permanent, leprosy-associated nerve damage. However, since there is no worldwide-implemented standard test for M. leprae infection, detection of infection in asymptomatic individuals remains a major challenge for control programs in endemic areas.

Several mycobacterial species are known to cause human diseases, such as tuberculosis and leprosy. In addition to these pathogenic species, there are also saprophytic representatives, which occasionally cause opportunistic infections. It is well established that numerous mycobacteria produce biofilms containing cellulose, and their genomes frequently harbor genes involved in cellulose degradation, such as celA1.
