Abstract

Tritrichomonas suis and T. foetus are characterized herein at the ultrastructural and biochemical levels. Microcinematography and measurements, scanning and transmission electron microscopy, cytochemistry for carbohydrate detection (Thiéry technique), and isozyme electrophoresis analysis were performed. In all, 11 different strains from 5 species of parasites were studied (T. foetus, T. suis, Trichomonas gallinae, T. vaginalis, and Monocercomonas sp.). A total of 11 enzymes were scored. Fine-structure study using scanning and transmission electron microscopy demonstrated that T.␣suis and T. foetus are identical morphologically. The high degree of isozymatic similarity noted between T.␣suis and T. foetus is consistent with the hypothesis that they may be different strains of the same species.
