Material type: materialTypeLabelBookPublisher: 2012Subject(s): Department of ParasitologyDDC classification: 1438,T Dissertation note: Trichomonas foetus (T. foetus) is a protozoan parasite of reproductive tract of large ruminants and causes abortion. This organism is found in males and females associated with varied pathology and clinical symptom. Disease has venereal transmission and male remain infected throughout the life. Pakistan is a developing country and artificial insemination facility is not available to all farmers and some are reluctant to avail it. This study was designed to check the prevalence of T. foetus in large animals in district Hafizabad. One hundred and fifty preputial and vaginal samples were collected from cattle and buffaloes 75 each. These samples were from 100 females and 50 males. Vaginal mucus from females was thoroughly examined for T. foetus in direct smear and in smear stained by Giemsa stain. Male samples were subjected to examination by direct smear, centrifugation and stained smear performed from sediments for detection of T. foetus. Overall prevalence of T. foetus was 12.0% (18/150) in sampled animals and species wise T. foetus infection was 8% (6/75) for cattle and 16% (12/75) for buffalos. Sex related prevalence of T. foetus in cows is 6% (3/50) and in buffaloes was 14% (7/50). Infection was more common in buffalo bulls 20% (5/25) as compared with cow bulls 12% (3/25). There was no difference in diagnosis of T. foetus in females by direct smear or by examination of stained smears. Whereas stained smears prepared from sediments of preputial washings were more sensitive in diagnosing of T. foetus infection as compared with direct smear method. Study also indicated that infection was exclusively seen in animals that were involved in natural breeding.
