背景据报道，干旱地区游牧牧民及其家畜中布鲁氏菌病的血清阳性率比肯尼亚非牧民农民及其家畜高10倍以上。在这里，我们比较了游牧牧民和混合牧民的血清阳性率与他们对布鲁氏菌病感染的疾病知识和高风险做法的了解。方法在基安布县和马尔萨比特县进行横断面研究，基安布县农民主要从事小农畜牧业和农作物种植，马尔萨比特县农民主要从事游牧畜牧业生产。采用分层随机抽样，首先根据主要畜牧业生产系统选择小区，然后使用随机生成的地理坐标选择家庭。在每个家庭中，随机选择最多3名5岁及以上的人，并同意进行布鲁氏菌Ig G抗体检测。向户主和选定的个人发放了一份结构化问卷，了解牧民和混合农民的疾病知识和危险行为。多变量混合效应Logistic回归模型用于评估与人布鲁氏菌属相关的独立实践。免疫球蛋白血清阳性。结果虽然大多数牧民家庭(74%)几乎没有受过正规教育，但超过70%的家庭(牧民和混合农民)听说过布鲁氏菌病，并提到其在人类中的临床表现。然而，只有不到30%的参与者(牧民和混种农民)知道布鲁氏菌病是如何在动物和人类之间传播的，或者知道如何防止其传播。尽管他们有类似的知识，但与从事危险行为的混种农民相比，血清阳性的牧民要多得多，包括食用生奶(79.5%比1.7%，p<；0.001)和生血(28.3%比0.4%，p<；0.001)，帮助动物分娩(43.0%比9.3%，p<；0.001)，以及处理生皮(30.6%比5.5%，p<；0.001)。0.001)。结论游牧牧民更有可能从事危险的做法，促进布鲁氏菌感染，可能是因为他们的职业和文化，尽管他们对这种疾病有大量的知识。
Background The seroprevalence of brucellosis among nomadic pastoralists and their livestock in arid lands is reported to be over10-fold higher than non-pastoralists farmers and their livestock in Kenya. Here, we compared the seroprevalence of nomadic pastoralists and mixed farming with their knowledge of the disease and high-risk practices associated with brucellosis infection. Methods Across-sectional study was conducted in two counties - Kiambu County where farmers primarily practice smallholder livestock production and crop farming, and Marsabit County where farmers practice nomadic pastoral livestock production. Stratified random sampling was applied, in which sublocations were initially selected based on predominant livestock production system, before selecting households using randomly generated geographical coordinates. In each household, up to three persons aged 5 years and above were randomly selected, consented, and tested for Brucella spp IgG antibodies. A structured questionnaire was administered to the household head and selected individuals on disease knowledge and risky practices among the pastoralists and mixed farmers compared. Multivariable mixed effects logistic regression model was used to assess independent practices associated with human Brucella spp. IgG seropositivity. Results While the majority (74%) of pastoralist households had little to no formal education when compared to mixed (8%), over 70% of all households (pastoralists and mixed farmers) had heard of brucellosis and mentioned its clinical presentation in humans. However, fewer than 30% of all participants (pastoralists and mixed farmers) knew how brucellosis is transmitted between animals and humans or how its transmission can be prevented. Despite their comparable knowledge, significantly more seropositive pastoralists compared to mixed farmers engaged in risky practices including consuming unboiled milk (79.5% vs 1.7%, p < 0.001) and raw blood (28.3% vs 0.4%, p < 0.001), assisting in animal birth (43.0% vs 9.3%, p < 0.001), and handling raw hides (30.6% vs 5.5%, p < 0.001)., Conclusion Nomadic pastoralists are more likely to engage in risky practices that promote Brucella Infection, probably because of their occupation and culture, despite having significant knowledge of the disease.
