摘要

布鲁氏菌病是一种重要的细菌性人畜共患病,在全球范围内造成了相当大的牲畜经济损失和健康负担。本研究旨在确定南非西北省四个地区(Dr Ruth Segomotsi Mompati、Ngaka Modiri Molema、Bojanala platinum 和 Dr Kenneth Kaunda 地区)社区和小农养牛场的布鲁氏菌病血清流行率。从养殖动物(n = 378)和屠宰场屠宰动物(n = 392)中收集了七百七十份血液样本。此外,还从泌乳的农场奶牛身上采集了牛奶样本(n = 22)。采用玫瑰红试验(RBT)、补体固定试验(CFT)和奶环试验(MRT)检测布鲁氏菌抗体。RBT显示血清流行率为2%,95%置信区间(CI:1.35-3.35),CFT证实所有四个抽样地区的总体血清流行率为1.95%(95%置信区间:1.14-3.12)。虽然布鲁氏菌病的血清流行率较低,但不能排除未发现该病病例的可能性。总体而言,研究结果证实布鲁氏菌病在南非西北省的调查地区呈地方性流行:本研究的结果将有助于农业、土地改革和农村发展部组织的国家布鲁氏菌病项目(2016-2026 年),协助有效实施疾病控制措施,以防止疾病在南非牛群中进一步爆发。

Seroprevalence of brucellosis in communal and smallholder cattle farming in North West Province, South Africa
Brucellosis is an important bacterial zoonosis responsible for considerable economic losses in livestock and health-related burden worldwide. The objective of this study was to determine the seroprevalence of brucellosis in communal and smallholder cattle farming in four districts of the North West province of South Africa (Dr Ruth Segomotsi Mompati, Ngaka Modiri Molema, Bojanala platinum and Dr Kenneth Kaunda districts). Seven hundred and seventy blood samples from farmed animals (n = 378) and abattoir-slaughtered animals (n = 392) were collected. In addition, milk samples (n = 22) were collected from lactating farmed cows. Rose Bengal test (RBT), complement fixation test (CFT) and milk ring test (MRT) were used to detect antibodies against Brucella species. The RBT showed a seroprevalence of 2% at 95% confidence interval (CI: 1.35–3.35), CFT confirmed an overall seroprevalence of 1.95% (95% CI: 1.14–3.12) for all four districts sampled. Although the seroprevalence of brucellosis was found to be low, the possibility of undetected cases of the disease could not be ruled out. Overall, the findings of this study confirmed that brucellosis is endemic in the surveyed areas of the North West province of South Africa.Contribution: The outcome of this study will contribute to the National Brucellosis Project organised by the Department of Agriculture, Land Reform and Rural Development (2016–2026) to assist in the effective implementation of the disease control measures with a view to prevent further outbreaks in the country’s cattle population.
