Conjugation in Spirostomum

Abstract

ANY report of conjugation in Spirostomum is of special interest because of its extreme rarity. To our knowledge the last report was by Bishop3 nearly thirty-six years ago in S. ambiguum. Earlier, Stein1 and Balbiani2 had observed the process in the same species. In no case was it noticed as a regular phenomenon (as in Paramecium and other ciliates) affecting considerable numbers of animals in a population. Nor were any of these authors able to present a full account of the conjugation process, since it was encountered by them very infrequently. As Bishop says, ‘There was no appearance of true epidemic’ of conjugation.
