A procedure for counting individual organisms or groups with very close cultural characteristics in complex mixtures is described. The method is based upon growth in a medium favourable to all organisms whose enumeration is attempted, selecting 20% of the colonies by the random number sampling method and submitting them to appropriate identification tests.
