title: [Research results on gamma-glutamyl-transferases and amino-peptidases in mycobacteria].
abstract: The activity of 68 mycobacteria strains belonging to 21 different species has been studied on 8 different chromogenic substrates utilized for determining the gamma-GT and various aminopeptidases. The assay was carried out using a simple method (bacterial suspension in solution M/10 of substrate and reading the result after 24 and 48h of incubation according to the color change) and interesting data were obtained about gamma-GT. This enzyme was present in all the strains of M.tuberculosis and in all the strains of the rapid growth species, absent in the other species. Thus, gamma-GT research is taxonomically and diagnostically useful in mycobacteria.
