Information About Trichomoniasis

Trichomoniasis is caused by a single celled flagellated protozoan parasite that is known to be a pathogen of the bovine reproductive tract as well as the intestinal tract of cats. It causes infertility, and, at times, has caused spontaneous abortions in the first trimester.

Samples for official T. fetus testing must be taken and submitted by an accredited veterinarian to one of the approved laboratories listed below. 

Bull ear tag ID and laboratory submission form: 

  • Bulls that are determined to be an official T. fetus PCR test negative by an official test shall be identified with an official Colorado negative T. fetus tag appropriate for the year in which the bull is tested.
  • The accredited veterinarian shall record the bull’s official identification device on the T. fetus test submission form or apply an official identification device to any bull that does not have one and record it on the T. fetus test submission form. 
  • All laboratory samples submitted for official tests for reportable diseases shall be accompanied by a properly completed form or electronic form approved by the State Veterinarian. Part 12.3 of the Colorado Livestock Disease Control Rule identifies what information must be provided on submission forms.  

Acceptable samples/media effective July 1, 2022 for use with the Trich RT-PCR:

  • Phosphate-buffered saline (PBS) 

  • Sterile Saline

  • Diamon's media

  • BioMed InPouches

  • BioMed Transit tubes

If Trich samples are not received at the laboratory within 144 hours, the sample can't be used for an official test. Consult with the Laboratory receiving Trich samples as to the appropriate days they may prefer to receive samples, if samples arrive at the laboratory on a Friday or Saturday it may cause difficulty with the Trich test being set up within 144 hours.
