The purpose of this study is to develop a method to diagnosis Tritrichnomonas fetus-infect bulls, and ultimately eradicate bovine trichomoniasis from cattle. Currently in US cattle. Tritrichnomonas foetus is the causative agent of Bovine Trichomoniasis, which may be zoonotic and capable of causing opportunistic infections in human beings. Tritrichnomonas foetus is a sexually transmitted protozoan disease. A signal mating service with an infected bull results in 95% infection among susceptible nulliparous cows. Infected bulls have no lesions and are clinically asymptomatic. In contrast infected heifers and cows exhibit an array of symptoms including endometritis, vaginitis, early abortions, and permanent infertility. Heifers and calfs can remained infected for up to 22 weeks after initial infection. This causes longer breeding seasons in affected herds. It has been an endemic in the United States for more than 80 years. It was first reported in 1932, since then the disease has been found in more than a dozen states. The majority of States have rules and regulation to reduce the spread of disease to curtail endemic disease and to minimize economic losses brought about by the disease mainly due to reduced calf crop, culling of bulls and veterinary expenses.
The hypothesis that is under investagation in this current review are diagnostic tests and related parameters, which are the bases of the US regulations. A better understanding of these may guide us in amore effective strategy in the war against the disease than the current regulations permit. A core component of these regulations is testing bulls for T. foetus, and positive bulls are culled due to lack of effective treatment regimens. Official tests vary fro...

...r of animals they are terrified and release hormones that permeate the meat products. In contrast New Zealand whose meat is highly prized has strict regulations for the breading (no hormones, no steroids), and slaughter of animals. The slaughter houses are strictly regulated to include At this point America is back tracking trying to recapture the essence of what was once so strong about our agricultural industry. In order to have “safe” meat we now are forced to go to whole foods and highly expensive stores and seek out safer alternatives in organic listed meats that are very expensive and are basically what was available to us in bulk in the fifties. Unfortunately, most of the meat products are not coming from America but rather New Zealand and other countries that kept a slower pace in embracing the push for meat that was bigger fatter and thus full of steroids.
