Abstract

Restriction fragment length polymorphism analysis has been used to assess relatedness among the genomes of four isolates of Mycobacterium leprae, the causative agent of leprosy. The M. leprae isolates were from human patients from India, a Mangabey monkey from West Africa, and an armadillo from Louisiana. A total of 16 probes were used; these were insert fragments of M. leprae DNA from plasmid recombinant libraries, 5 of which had genes with identifiable functions and 11 of which were randomly chosen recombinant molecules. In spite of the widely diverse origins of the isolates, restriction fragment length polymorphism analysis demonstrated that less than 0.3% of the nucleotides differ among the genomes.
