Tritrichomonas foetus causes a venereal disease in cattle called bovine trichomoniasis. T. foetus lives in the reproductive tract of the cow, the surface of the penis and prepuce of the bull and causing early fetal loss and sometimes late term abortions. It can also extend breeding / calving season. In this study, 155 cows of different ages (2-6 years old) and with a variety of clinical signs (repeat breeders, abortions, and discharge only) were examined from different areas in Basrah Province, Iraq from November 2020 to July 2021, and 75 samples collected from healthy animals (without any symptom). The infection rate was detected in wet mount techniques found fewer positive findings than in pouch techniques, with 12 (40%) recorded and in pouch systems, 30 (100%) recorded while in the culture 24(80 %), Giemsa-stained smears 19(63.3%) and Acridine orange was 20 (66.6%). The present study improved that cows more than three years are more susceptible to be infected than cows less than three years. The study concluded that if no control method is applied in Basrah, there is a serious risk of spreading Trichomonas foetus.

New tellurated schiff bases were synthesized by the reaction of the corresponding mercurated Schiff  bases compounds A1-A3 with tellurium tetrabromide in 1:1 mole ratio and  that  gave organyltellurium tribromides  A4-A6.  On the other hand, when mercurated schiff bases and tellurium tetrabromide brought  together in 2:1 mole ratio gave diorganyltellurium dibromides compounds A10-A12 followed by reduction with hydrazine hydrate gave new diorganyl tellurides A13-A15. Reduction of compounds A4-A6 by hydrazine hydrate gave new ditellurides A7-A9.  All compounds were characterized by elemental analysis, IR, 1H , 13C NMR, HSQC-NMR and mass spectra. Invitro anti-tumor bioactivity of some compounds were tested.Â

A series of Schiff bases 7-11 derived from dibenzoylmethane have been prepared. The UV, IR, 1H NMR and mass spectra revealed theses compounds were existed mainly as the keto-enamine tautomer in the solution. The absorption bands which appeared in the range λmax = 376-406 nm were assigned to the electronic transitions which arised from the central hydrogen bonded chelated unsaturated ring system in this tautomer. The appearance of the broad singlet near d  = 13 ppm due to the N-H proton and a singlet near d  = 6 ppm due to the –C=C-H proton inaddition to benzoyl fragment ion     signal m/z =105 in the mass spectra supported the above suggested products.
