Bovine brucellosis (BB) is a cosmopolitan zoonotic disease caused by certain bacteria of the genus Brucella. It has negative health implications for the cattle, economic implications for the owners and is present in numerous cattle and wildlife populations worldwide. To determine the seroprevalence of BB in dual-purpose herds and assess its impact in the southern part of the Department of Atlántico, northern Colombia. 1,000 female cattle were tested for brucellosis, using the Rose Bengal Plate Test (RBPT) and indirect ELISA (iELISA) as screening and confirmatory tests, respectively. Of these, 100 animals tested positive by RBPT and 204 were inconclusive, while 38 positive animals were identified by iELISA. Consequently, the apparent seroprevalence was 3.8%, and the estimated true prevalence was 4.4%. Based on estimates of the economic losses caused by BB, the cost was calculated at $2,496,364 COP ($822 USD) per animal. The costs identified in this study include medication costs, loss of lactation, and others. It highlights the significant impact of BB on food security, particularly concerning the availability of and access to bovine food products, as well as on the economy of livestock farmers in the region.
牛布鲁氏菌病（BB）是一种世界性的人畜共患传染病，由布鲁氏菌属的某些细菌引起。它对牛的健康有负面影响，对畜主的经济有影响，并且在全球许多牛和野生动物群体中存在。为了确定哥伦比亚北部大西洋省南部双用途牛群中的布鲁氏菌病血清流行率，并评估其影响。使用虎红平板试验（RBPT）和间接酶联免疫吸附试验（iELISA）分别作为筛选和确认试验，对 1000 头母牛进行了布鲁氏菌病检测。其中，100 头 RBPT 检测呈阳性，204 头检测结果不确定，38 头 iELISA 检测呈阳性。因此，显性血清流行率为 3.8%，估计真实流行率为 4.4%。根据布鲁氏菌病造成的经济损失估计，每头动物的成本为 2496364 哥伦比亚比索（822 美元）。本研究确定的成本包括药物成本、泌乳损失和其他成本。它突出了 BB 对食品安全的重大影响，特别是对牛类食品的供应和获取，以及对该地区牲畜饲养者经济的影响。
