[Use of media with antibiotics for isolating resistant forms of the cholera vibrios].

Higher stability of resistance to tetracycline in the polyresistant strain of V. eltor under conditions of macroorganism as compared to nutrient media was found experimentally. To increase isolation of the resistant forms of the cholera vibrio it was recommended to use agar with tetracycline or other antibiotics depending on the particular case in addition to the routine media.
