Bovine Tritrichomonosis (trichomonad disease) is a disease transmitted by unicellular parasites (Tritrichomonas foetus) during mating.
Worldwide; in Central and Western Europe the trichomonad disease has been largely eradicated.
Mode of transmission
Bovine tritrichomonosis is transmitted during mating. Bulls can be lifelong carriers and excretors of the parasite.
Early abortions usually occur 2-4 months after mating.
In cows, early abortions, frequent re-calving, prolonged calving intervals, sterility. Bulls often show no clinical symptoms.
Insemination bulls are monitored to prevent reintroduction of the pathogen into domestic herds. Chemotherapeutic agents are not approved. In females, only symptomatic treatment is indicated if clinical signs occur.
The most effective prevention in cattle is artificial insemination. Although transmission with frozen semen is also possible with artificial insemination, it occurs very rarely because of the regular examination and isolated husbandry of the insemination animals.
