Abstract

In 2001, antibodies to Brucella spp. were detected in the wild boar (Sus scrofa) population of Regional Park in the Piedmont, northwest Italy. This was the first report of swine brucellosis in Italian wildlife, and in response, we conducted a survey on wild boars culled in the park to evaluate the presence and epidemiologic pattern of Brucella. In total, 2,267 serum samples and 1,841 tissue samples were collected and tested from 2001 to 2007. Differences in antibody and infection prevalence among sampling years were statistically significant (chi(2)=28.2, P<0.0001 and chi(2)=27.8, P<0.0001, respectively). Serologic and culture results also differed between gender and age groups, and for serology, a positive age trend was observed in both male and female age classes (chi(2(trend))=90.9, P<0.00005 OR: 1, 2.5, 4.9, 7.5; chi(2(trend))=43.1, P<0.00002, OR: 1, 2.5, 2.9, 4.8, respectively).

摘要

2001年，在意大利西北部皮埃蒙特地区公园的野猪（Sus scrofa）种群中检测到布鲁氏菌属抗体。这是意大利野生动物感染猪布鲁氏菌病的首次报告，作为回应，我们对公园内捕杀的野猪进行了一项调查，以评估布鲁氏菌的存在情况和流行病学模式。2001年至2007年期间，共收集并检测了2267份血清样本和1841份组织样本。各采样年份之间抗体和感染率的差异具有统计学意义（分别为χ² = 28.2，P < 0.0001和χ² = 27.8，P < 0.0001）。血清学和培养结果在性别和年龄组之间也存在差异，对于血清学，在雄性和雌性年龄组中均观察到阳性年龄趋势（χ²（趋势）= 90.9，P < 0.00005，OR：1，2.5，4.9，7.5；χ²（趋势）= 43.1，P < 0.00002，OR：分别为1，2.5，2.9，4.8）。
