Abstract

The effect of treatment by a number of antineoplastic agents on the growth, ultrastructure and macromolecular synthesis of T. glabrata was studied. Many differences were noted in the response of this yeast to these agents. Thiotepa and methotrexate inhibited the growth of T. glabrata, while it was resistant to endoxan-asta and vincristine sulphate.

A variation of morphological response of T. glabrata was also observed. Methotrexate enhanced filamentation while thiotepa influenced the surface structures of the cells, resulting in loss of cytoplasmic materials and cell collapse. The other two drugs had little or no effect on the morphology of the yeast tested.

The incorporation of precursors for macromolecular synthesis of T. glabrata in the presence of thiotepa and methotrexate was restricted. Thiotepa affected the uptake of precursors of RNA, DNA and protein limiting them to between 62 and 66% of the control values. In contrast, methotrexate limited the uptake of macromolecular precursors to a lesser extent. The possible mechanism of action of antineoplastic agents against yeast and the clinical implications of these findings are discussed.
