title: [Efficiency of inhibitors (phenylethanol, nalidixic acid, sodium azide)in the isolation of strictly anaerobic bacteria from a polymicrobial specimen].
abstract: The efficacy of inhibitors (PEA, Ac Nal, Az de Na) in the isolation of strict anaerobes in polymicrobial sample. The efficacy of three inhibitors to select strict anaerobic bacteria in the polymicrobial sample had been studied. First step: The most frequent anaerobes encountered in the infections are isolated in the agar Columbia containing the different inhibitors. This step allowed us to check the inhibition of the germ we have to isolate. Next step: polymicrobial mixtures were made. The composition of which is very similar to the samples we receive in the laboratory. The swarming Proteus is the facultative anaerobic germ which gives us difficulties when isolating strict anaerobic bacteria. Then, the different mixtures were isolated separately in the agar in which the inhibitors were added. The plates containing Azide of Na and PEA gave us the best results.
