1. TRICHOMONIASIS PREPARED BY B.V.Sc. & A.H. BACTH ROLL NO: 26-38  

2. Trichomoniasis is a venereal disease caused by Tritrichomonas foetus, characterized by asymptomatic infection in bulls and early pregnancy termination, infertility, and reproductive tract inflammation in cows, leading to significant economic losses. INTRODUCTION fig: Tritrichomonas foetus

3. CAUSED BY PROTOZOA OF ETIOLOGY Bovine Trichomoniasis is caused by Tritrichomonas foetus

4. MODE OF TRANSMISSION Primarily transmitted by coitus As T. foetus can also survive the process used for freezing semen, so gets transmitted when the semen from infected bulls is used for AI TRANSMISSION

5. PATHOGENESIS

6. Demonstration of Tritrichomonas foetus Vaginal, uterine or preputial exudates Herd history of decreased fertility, abortions, vaginitis, metritis and balanitis Diagnostic Methods Direct microscopic examination Culture of organisms (more accurate) DIAGNOSIS

7. Campylobacteriosis Leptospirosis Brucellosis Chlamydiosis Bovine viral diarrhoea These may cause clinical signs including infertility, vaginitis, pyometra, abortions and vaginal discharge DIFFERENTIAL DIAGNOSIS

8. Female Reproductive Tract Usually non-specific inflammation Pyometra may develop Fetal Lesions Often absent Possible pyogranulomatous bronchopneumonia in late gestation abortions GROSS LESIONS

9. In Bulls Mild mononuclear and neutrophilic inflammation in penis and prepuce In Cows Non-specific inflammation in reproductive tract Pyogranulomatous bronchopneumonia in aborted fetuses MICROSCOPIC LESIONS

10. Regular testing of bulls Cull or treat infected bulls Biosecurity measures to prevent spread Vaccination programs (where available) Good herd management practices CONTROL

11. Trichomonas suis in pigs (digestive and upper respiratory tract) Trichomonas gallinae in pigeons (pathogen of mouth, crop, oesophagus) Trichomonas vaginalis in humans (vagina, urethra, prostate) Trichomonas equi in horses (intestinal tract) Tritrichomonas & Trichomonas are common inhabitant of GIT & are commonly associated with enteritis and diarrhea in various domestic animals TRICHOMONIASIS IN OTHER ANIMALS
