[Comparison of the efficiency of a modified Ogawa medium and the media used for culture investigation on tuberculosis in routine (author's transl)].

In cooperation of nine laboratories a modified Ogawa medium containing asparagine was compared with the media used in the GDR for culture investigations on tuberculosis in routine [German Pharmacopoeia (diagnostic laboratory methods) GDR]. The efficiency of the modified Ogawa medium containing asparagine instead of sodiumglutamate was comparable to that of the original Ogawa medium and did not show any better results. By this means it is once more evident that Ogawa medium is an efficient medium for culture on tuberculosis. It is less liable to contamination and easily to be prepared.
