title: [Morphologic and biologic properties of diphtherroid organisms (LDC) isolated in leprosy].
abstract: Acid-alcohol-fast bacteria are not always detectable in all leprosy lesions. Non acid-fast microorganisms may be associated with acid-fast bacteria. The most frequently isolated strains from leprosy lesions are non acid-fast bacteria, morphologically related to C. diptheirae. Hence their designation as diphtheroïds or LDC (leprosy derived corynebacteria). Their antigenic structure is more closely related to M. leprae and other mycobacteria than to classical corynebacteria. This leads to the hypothesis of a potential role in the pathogenesis of leprosy and their use as an antigen for skin tests by leprosy patients.
