| | Resumo: | The complete 1493 nucleotide sequence of the 16SrRNA gene of the leproma-derived and cultivable mycobacterium HI-75 strain was analyzed to elucidate the taxonomic characteristics by direct sequencing of the polymerase chain reaction (PCR) products. The results revealed that the sequence of mycobacterium HI-75 was mostly similar to that of Mycobacterium scrofulaceum with 5 bases differences in the sequenced 1493 bases (0.35%) of the 16SrRNA gene. M. leprae differed from the strain with 47 bases (3.3%). Sasaki and Hamit reported the nerve-invasive activity of the inoculated mycobacterium HI-75 in nude mice or the 131I-treated immunocompromised Swiss mice. The results indicate that mycobacterium HI-75 could be a mutant of M. scrofulaceum possessing the ability to invade the peripheral nerve in addition to developing leproma-like lesions. (AU)^ien.
