    Abstract:
    The following study gives review of the results of the phagetyping of M. tuberculosis strains in different localities of Czechoslovakia and German Democratic Republic (165 strains from Czechoslovakia and 102 strains from GDR) and the comparison of the occurrence of phage subgroups of M. bovis strains in two different localities of Czechoslovakia (62 strains) and Argentina (93 strains). The results of the phagetyping of the Czechoslovak M. tuberculosis strains show that this group comprises all the 6 phage subgroups and agree very well in subgroups Ax, A2, B and C with the M. tuberculosis strains from GDR. Both groups of strains differ in subgroups A2 (9) and D. The results with the fresh isolated Argentinian M. bovis strains show that this group has only subgroups Ax and D in comparison with the old laboratory strains of M. bovis which have subgroups Ax, A2(9), and D. The phagetyping of the M. tuberculosis and M. bovis strains was undertaken with the help of 11 international mycobacterial phages. The use of mycobacterial phages in 1 RTD (Routine Test Dilution) and 10 RTD concentrations (in contrary to the 1 RTD and concentrated phage suspensions used previously) decreased the number of the "unspecific" reactions.
