o-Diphenoloxidase of Mycobacterium leprae separated from infecected armadillo tissues.
We reported earlier the occurrence of a unique o-diphenoloxidase in Mycobacterium leprae recovered from lepromatous human tissues. No other source of M. leprae fro biochemical studies was available at the time. In the present report, properties of phenoloxidase in M. leprae separated from infected armadillo tissues are presented. The results show that the o-diphenoloxidase remains unaltered in ...
متن کاملPartial nucleotide sequence of 16S ribosomal RNA isolated from armadillo-grown Mycobacterium leprae.
Ribosomal RNA (rRNA) was isolated from Mycobacterium leprae recovered from infected tissue of the Nine-banded Armadillo, and nucleotide sequences near the 3' end of the 16S species were determined by primer extension in the presence of dideoxynucleotides. Previously published data for bacterial 16S rRNAs show a pattern of conserved and non-conserved sequences that fit a common secondary structu...
متن کاملIn vitro cultivation of mycobacteria from human lepromas and from an armadillo infected with mycobacterium leprae.
Experimental evidence has been presented that the host-grown, hitherto noncultivated mycobacteria, M. leprae and M. lepraemurium are metabolically competent microorganisms (1. 5.6. X. II . 12. 14). They are provided with a complete and functional tricarboxylic acid cycle and electron transport chain. We also described ( 5.6. 10. II . JJ) that M . leprae and M. lepraemurium have the capacity to ...
متن کاملSuperoxide dismutase, peroxidatic activity and catalase in Mycobacterium leprae purified from armadillo liver.
Superoxide dismutase has been identified and peroxidatic activity demonstrated in Mycobacterium leprae. The superoxide dismutase, shown indirectly to be a manganese-containing enzyme, was present at low activity in the cell-free extract. Peroxidatic activity was detected in a haemoprotein on polyacrylamide gels, but quantitative assay was not possible. Catalase, although present in a cell-free ...
متن کاملStaining of Mycobacterium leprae by the Rio Hortega silver method in frozen and paraffin sections.
It has been recognized for some time that Mycobacterium leprae has the property of staining with the silver methods (2). However, there has not been described a simple, quick and easy technique for staining the bacillus in that way, applicable to either frozen or paraffin sections. It is my purpose to present a method which satisfies these requirements, and which also shows a new aspect of this...
