Brucellosis is considered the most important zoonosis in Jordan with high prevalence among man and livestock.
This study was carried out on high risk people in 1992 in order to assess the seroprevalence of brucellosis in northern Jordan. The sera of 1236 individuals (636 at high risk and 600 controls) were evaluated using the Rose Bengal plate agglutination test (RBPT) and enzyme-linked immunosorbent assay (ELISA-IgG) tests.
A significantly (P < 0.05) higher seroprevalence of brucellosis among high risk people (8.2 percent) compared to the control sample (0.5 percent) was found. The overall seroprevalence was significantly higher among sheep farmers and meat handlers than in other occupations tested. The seroprevalence increased with age and years at work, but was not influenced by sex or locality. The results indicated a higher seroprevalence among veterinarians in northern Jordan, compared to central Jordan but the difference was not significant. Seroprevalence was present only among veterinarians working in clinics especially in the working age group (34-43 years).
The results of this study emphasized the importance of contact infections, namely contact with infected animals and their products, as a method of transmission of brucellosis compared to ingestion of contaminated animal products.
布鲁氏菌病被认为是约旦最重要的人畜共患病，在人和牲畜中流行率很高。
1992年对高危人群开展了本研究，以评估约旦北部布鲁氏菌病的血清流行率。使用玫瑰红平板凝集试验（RBPT）和酶联免疫吸附测定（ELISA-IgG）试验对1236名个体（636名高危个体和600名对照）的血清进行了评估。
发现高危人群中布鲁氏菌病的血清流行率（8.2%）显著高于对照样本（0.5%）（P<0.05）。绵羊养殖户和肉类处理人员中的总体血清流行率显著高于其他接受检测的职业。血清流行率随年龄和工作年限增加，但不受性别或地区影响。结果表明，约旦北部兽医中的血清流行率高于中部约旦，但差异不显著。血清阳性仅出现在诊所工作的兽医中，尤其是在工作年龄组（34 - 43岁）。
本研究结果强调了接触感染（即接触受感染动物及其产品）作为布鲁氏菌病传播途径的重要性，与摄入受污染动物产品相比。
