Trichomoniasis, caused by the protozoan Tritrichomonas foetus, is a serious reproductive (venereal) disease found in some Utah cattle herds. Diagnosis of trichomoniasis is made when trichomonad organisms are detected in the smegma or preputial flush samples of bulls, or the uterine/vaginal fluids of cows
