Final answer:
Tritrichomonas foetus can be diagnosed by performing a vaginal/preputial wash or a culture. Microscopic evaluation of wet mounts is an inexpensive and convenient method of diagnosis, but the sensitivity of this method is low.
Step-by-step explanation:
Tritrichomonas foetus can be diagnosed by performing a vaginal/preputial wash or a culture. Microscopic evaluation of wet mounts is an inexpensive and convenient method of diagnosis, but the sensitivity of this method is low. Nucleic acid amplification testing (NAAT) is preferred due to its high sensitivity. Using wet mounts and then NAAT for those who initially test negative is one option to improve sensitivity. Samples may be obtained for NAAT using urine, vaginal, or endocervical specimens for women and with urine and urethral swabs for men.
