| isolation and characterization of an environmental acid-fast organism producing diphenoloxidase activity in vivo. | water and soil samples were collected from natural habitats of the nine-banded armadillo and tested for the presence of acid-fast organisms by injection into the foot pads of experimental mice. sixteen months post inoculation an acid-fast organism was isolated from the foot pad and spleen of one of the mice. the isolate exhibited diphenoloxidase activity as determined by its ability to convert d-3,4-dihydroxyphenylalanine to the corresponding quinone. the same organisms grown in vitro lacked det ... | 1990 | 2118868 |
