Web16. okt 2007 · In our usage, the ‘T. pyriformis’ complex includes all species previously known under that name as varieties, syngens or phenosets (Nanney and McCoy 1976). Present evidence indicates that Tetrahymena is a monophyletic genus, though this has been disputed (Jerome and Lynn 1996). Table 1 lists the species in the genus Tetrahymena. WebTetrahymena pyriformis belonging to phenosets A (original strain GL/Zeuthen) and B (original strain E/Elliott) were obtained from the Cambridge Collection of Algae and Protozoa. The animals were maintained by weekly subculture in sterile 2 per cent proteose-peptone and 0. 5 per cent yeast extract (Difco Laboratories, Detroit) pH 7, at 28°C.

The proposal that new strain designations be assigned on a basis of “phenoset” conformity is reaffirmed.
