Bovine trichomonosis (BT) is a contagious disease, characterized by reproductive failure, embryonic losses, infertility, and abortions, which directly impacts the reproductive performance of cattle. In this cross-sectional questionnaire-based study, 56 veterinarians provided information on the geographic location and on the demographic, husbandry, and sanitary characteristics of 173 beef herds located in 26 (21%) counties of the Province of Buenos Aires, Argentina. Herds rearing beef cattle (OR=2.5, 95% CI=1.0, 6.3), with low pregnancy rate in cows (<or=90%) (OR=4.1, 95% CI=1.5, 10.8), sharing livestock with other owners or farmers (OR=5.4, 95% CI=1.8, 16.5), and where trichomonosis was reported during the previous year (OR=4.1, 95% CI=1.7, 9.6) were at significantly greater risk of being BT positive. This study provided information for future risk assessment and/or management plans for the prevention and control of BT in a region where the disease is considered to be endemic.
牛毛滴虫病（BT）是一种传染性疾病，其特征为繁殖失败、胚胎损失、不育和流产，直接影响牛的繁殖性能。在这项基于问卷调查的横断面研究中，56名兽医提供了位于阿根廷布宜诺斯艾利斯省26个（21%）县的173个肉牛群的地理位置以及人口统计学、饲养管理和卫生特征信息。饲养肉牛的牛群（比值比=2.5，95%置信区间=1.0，6.3）、母牛怀孕率低（≤90%）的牛群（比值比=4.1，95%置信区间=1.5，10.8）、与其他所有者或农户共享牲畜的牛群（比值比=5.4，95%置信区间=1.8，16.5）以及上一年报告过毛滴虫病的牛群（比值比=4.1，95%置信区间=1.7，9.6）感染BT呈阳性的风险显著更高。本研究为该病被视为地方病的地区未来预防和控制BT的风险评估和/或管理计划提供了信息。
