[Sensitivity tests of mycobacteria to INH, SM, EMB and RMP in a semi-liquid serum-sauton-agar (author's transl)]

Abstract

In this article a simple method of sensitivity testing of mycobacteria in semi-liquid serum-sauton-agar as AHSK-test is described and first results are reported. The sensitivity to INH, SM, EMB and RMP is tested. In comparative tests between the economical-test and the AHSK-test a total of 100 strains of mycobacteria of different sensitivity are investigated. The results largely agree with each other, from which the evaluation of the sensitivity test in the AHSK-test in 54% of the strains after 7 days, in 40% after 14 days and in 6% after 21 days follows. The simple composition and preparation of the culture medium as well as the rapid and characteristic growth of M. tuberculosis and M. bovis make the AHSK-test to a simple, economical and rapid method for sensitivity testing.
