Abstract
1) SM resistant cases were 198 to 224 cases (88.0%) by dilution method and 191 (contai-ning low resistant cases)to 224 (84.9%). The results were good coincident.
2) PAS resistant cases were 162 to 211 cases (76.8%) by the former and 159 (71.4%) by the latter.
3) INA resistent cases were 163 to 225 cases (72.8%) by the former and 159 (71.4%) by the latter.
4) Thus, the results by both methods were proved to be relatively coincident and by repeated tests the results were certified to be fast the same.
5) So, the vertical diffusion method was confirmed to be reliable for routine work of resistance examination of the tbc. -bac. against antibiotics.
