The quick-freezing and freeze-etching techniques were used to analyze surface domains of Tritrichomonas foetus. The surface of the protozoan body was not smooth, presenting surface projections, except on the flagellar surface. Images of the actual surface of the anterior flagella revealed the presence of intramembranous particles that form rosettes, as observed on the protoplasmic fracture face. They may represent integral transmembrane proteins exposed at the cell surface. Surface specializations were also observed at the flagella base and where the recurrent flagellum attaches to the cell body.
