“…The proportionate prevalence of reproductive cases in older animals (42.1-87.5) % with higher parity (31-87.5)% was higher in this study, is agreed with many studies [19,20]. Animals with artificial insemination were more susceptible to reproductive cases in the previous study which is coincided with the result of [21]. Most of the reproductive cases were corrected manually where the complicated cases were corrected by caesarean operation.…”

Reproductive disease is a generic term that refers to all diseases which affect the organs of reproductive system in animals. It occurs in cattle buffalo, sheep, goat, horse etc. and causes heavy economic loss by reducing the reproductive activity of the animal along with calf mortality. The study was undertaken to know the proportionate prevalence of reproductive cases in cattle and buffalo in Veterinary College and Research Institute (VCRI), Namakkal and Madras Veterinary College (MVC), Tamilnadu, India .The duration of the study was 1.5 months and total 286 of different cases were registered during the study period. Both retrospective and prospective reproductive cases were included in this study. The proportionate prevalence of different reproductive cases were respectively 5.2% and 8.8% dystocia;4.6% and 5.3% respectively retained placenta;3.5% and 7.9% abortion respectively; 2.9% and 2.7% ovarian cyst respectively in VCRI and MVC. Reproductive cases were more frequently occurred in cross-breeds. Older animals (42.1-87.5) % with higher parity (31-87.5) %was susceptible to reproductive cases. Antibiotics and hormonal drugs were used for the treatment of reproductive cases. Most of the reproductive cases /dystocia were corrected manually where the complicated cases were performed by caesarean operation.

“…However, there was no evidence of fetal infection (48,49). Bovine herpesvirus 1 (BHV-1), one of the most common viral pathogens in bovine semen, may also be associated with a decrease in semen quality, and bull semen is therefore systematically tested for this virus before being used for insemination (106). BHV-1 is present in the seminal plasma rather than the cell fraction (337).…”

This review describes the various viruses identified in the semen and reproductive tracts of mammals (including humans), their distribution in tissues and fluids, their possible cell targets, and the functional consequences of their infectivity on the reproductive and endocrine systems. The consequences of these viral infections on the reproductive tract and semen can be extremely serious in terms of organ integrity, development of pathological and cancerous processes, and transmission of diseases. Furthermore, of essential importance is the fact that viral infection of the testicular cells may result not only in changes in testicular function, a serious risk for the fertility and general health of the individual (such as a fall in testosteronemia leading to cachexia), but also in the possible transmission of virus-induced mutations to subsequent generations. In addition to providing an exhaustive account of the data available in these domains, this review focuses attention on the fact that the interface between endocrinology and virology has so far been poorly explored, particularly when major health, social and economical problems are posed. Our conclusions highlight the research strategies that need to be developed. Progress in all these domains is essential for the development of new treatment strategies to eradicate viruses and to correct the virus-induced dysfunction of the endocrine system

“…A limitation of the current study is that the samples were not concomitantly tested for other abortion-causing pathogens such as viruses, bacteria, fungi and parasites (Eaglesome & Garcia, 1997;Thibier & Guerin, 2000). In a survey of pathogens by PCR from 80 aborted bovine foetuses in Beijing, China, infectious agents were detected in 45 (56.3 %), 22 (48.9 %) of which represented co-infections with two or three infectious agents.…”

Tritrichomonas foetus infections in female beef cattle with abortion in Wyoming, USA

Introduction: Bovine trichomoniasis has been endemic in the USA since its discovery in the 1930s. Testing of bulls used for reproduction is currently mandated in 26 states to control spread of the disease. Although individual head prevalence in Wyoming has decreased since 2000 when the state's regulation started, the herd prevalence remains steady and the disease continues to have a wide geographic distribution. One factor neglected in current regulations is the role of infected cows/heifers in transmission. The latter may harbour Tritrichomonas foetus, the causative organism, up to a few weeks post‐abortion/parturition. This capacity enables them to spread the disease in spite of extensive bull testing. Case presentation: The purpose of the present study was to determine the prevalence among Wyoming beef cattle of detectable T. foetus infection in cows/heifers with a history of abortion for which samples had been tested. This retrospective study included all submissions to the Wyoming State Veterinary Laboratory between 2000 and 2010. Cows/heifers with a history of abortion among Wyoming producers were tested for trichomoniasis. Overall prevalence was 9.7 %. Furthermore, 4.5 % of aborted foetuses were positive. Conclusion: Our data collectively demonstrates that a percentage of cows/heifers that recently experienced abortion are positive for T. foetus and may play an important role in maintaining endemicity of bovine trichomoniasis.
