A parasitic protozoan with four to six flagella and an undulating membrane, infesting the urogenital or digestive system.
- ‘Saline microscopy permits identification of trichomonads and clue cells, as well as other additional information.’
- ‘However, published data for hydrogenosomes in trichomonads, ciliates, and chytrid fungi are consistent with them sharing common ancestry with mitochondria.’
- ‘The absence of functional mitochondria in protists such as trichomonads suggests that they diverged from other eukaryotes prior to the alpha-proteobacterial symbiosis that led to mitochondria.’
- ‘The mobile clinic's microscope is not state-of-the-art, but it was clear enough to see the hyperactive flagellated trichomonads scurrying around the field.’
- ‘For microscopic examination of the vaginal discharge, warming the slide and decreasing the intensity of substage lighting are ways to increase sensitivity for trichomonads.’
Mid 19th century: from modern Latin Trichomonadida (plural), from Greek thrix, trikh- hair + monas, monad- unit.
