[Methods and experiences in the detection of bacterial toxins or their antibodies using diffusion counterimmunoelectrophoresis].

It could be ascertained that the quantitative and qualitative identification of bacterial antigens and antibodies can be improved and completed, respectively, by DCIE in selected indications given. The diffusion counter immunoelectrophoresis has several advantages (easy handling, saving of time, easy evaluability). Our own tests confirmed the possibility of developing DCIE as a screening method to identify diphtheria and tetanus antibodies.
