How many Trich species can be detected in cattle?
Three genera, with multiple species, make up the majority of trichomonads found in cattle: Tritrichomonas, Tetratrichomonas, and Pentatrichomonas. Within these categories, only one species of Tritrichomonas (Tritrichomonas foetus), many species of Tetratrichomonads, and one species of Pentatrichomonas (Pentatrichomonas hominis) are routinely detected in cattle. Tritrichomonas foetus is the only one of these protozoa that causes trichomonosis.
