摘　　要：本研究采用横断面研究方法,通过两个阶段的随机抽样检测,结合问卷调查,获得大连市羊群布鲁氏菌病血清流行率及感染风险因素,初步了解了当地养羊场户对布鲁氏菌病防控相关知识的掌握情况和行为实践特点。研究结果表明,大连市羊布鲁氏菌病场群血清流行率为8.89%(95%CI:6.14%~11.63%)。从饲养模式看,调查的6个种羊场均无布鲁氏菌病感染,而商品代饲养场和散养村羊群布鲁氏菌病血清流行率分别为13.33%(95%CI:5.64%~21.03%)和8.21%(95%CI:5.24%~11.17%),差异不显著(X^2=1.93,p=0.17>0.05)。从饲养品种看,不同品种羊群之间的布鲁氏菌病血清流行率差异也不显著(X^2=0.15,p=0.93>0.05)。单因素分析结果表明,"与其他养羊场户共用种公羊""产后胎衣丢弃和喂狗""流产物喂狗""与其他养羊场户共用交通工具""近一年羊贩子进羊圈""近一年在交易市场买卖羊"等行为是羊群感染布鲁氏菌病的风险因素,而"购入前检测布鲁氏疾病"是显著的保护性因素。进一步的logistic回归分析表明,"近一年在交易市场买卖羊"(OR=4.91,95%CI:1.57%~15.35%)"流产物处理不当"(OR=1.87,95%CI:1.06%~3.30%)是主要的羊群布鲁氏菌病感染风险因素。"知信行"调查结果表明,大连市养羊从业者对布鲁氏菌病的认知程度较好,说明兽医部门的宣传工作有成效。但从行为实践角度来看,仍有部分养羊场户存有侥幸心理,在日常养殖和生活中不采取降低布鲁氏菌病感染风险的措施。A cross-sectional study to estimate the farm-level seroprevalence of brucellosis in sheep and goats in Dalian district was carried out by using a two-stage random sampling strategy,together with a survey of risk factors and knowledge,attitudes and practices（KAPs）among local shepherds. The estimated true seroprevalence in Dalian was 8.89%（95%CI：6.14%～11.63%）.All 6 breeding farms were seronegative. The estimated seroprevalence of commercial farms and backyard villages were 13.33%（95% CI：5.64%～21.03%）and 8.21%（95% CI：5.24%～11.17%）,and there was no significant difference between the two feeding patterns（X^2 =1.93,p=0.170.05）,and among different breeds（X^2 =0.15,p=0.930.05）. In the logistic model,two variables were significantly associated with higher odds of seropositivity：traded ovine in market recent 1 year（OR=4.91,95% CI：1.57%～15.35%）and feeding aborted material to dogs（OR=1.87,95% CI：1.06%～3.30%）.Results of the KAPs showed that the awareness of local shepherds for brucellosis were good,and the propaganda work of veterinary department was effective. But some high-risk practices,such as assisting parturition without protective measures and abandon aborted material,were still in existence.
