Abstract1. 3 vols. H2O2 Jungmann’s method for 30 minutes is better than the original 10 vols. H2O2 Jungmann’s method for 10-12 minutes, because the former gives more positive cultures and is easier to work with particularly when there are many specimens to be dealt with at a time. 2. 3 vols. H2O2 Jungmann’s for 30 minutes is better than 1 vol. H2O2 Jungmann’s method for 30 minutes because the former gives lesser contaminations. 3. Petroff’s method (NaoH 4%) is better than Jungmann’s method or any of its modifications as the former gives greater number of positive cultures and minimum contaminations.
