摘要
目的通过对山东省马楼村貂养殖户用来自布鲁杆菌病(布病)疫区的死羊羔肉喂貂情况的调查,分析养殖人员感染水平及危险暴露方式。方法以2004年1月～2005年7月马楼村养殖人员出现布病临床症状,伴布鲁杆菌试管凝集试验滴度≥1∶100者为调查对象。选择25例病例、125名健康养貂人员进行病例对照研究,比较从事养貂各作业环节的暴露方式和频度等。结果发病率8．7%；“购买死羊羔肉”比值比(OR)=4．4[95%可信区间(CI)=1．3～16．0]；“清洗死羊羔肉”OR值南“从不”清洗组的1．0上升到“总是”清洗组的13．0,存在暴露剂量一反应线性趋势(x^2=10．95,P＜0．05)。结论疫情的发生主要与养殖人员接触来自畜间布病流行疫区生的死羊羔肉有关。建议加强畜产品交易市场管理和检疫,教育公众防护知识。
Objective To analyze the possibility of infecting brucellosis and the risky exposure of ermine breeders through an investigation on the ermine breeders in Malou Village of Shangdong Province breeding their ermine with raw lamb meat from endemic brucellosis areas. Methods Villagers who bred ermines with symptom of brucellosis, plus a brucella serum agglutination（SAT） titer ≥ 1 ： 100 with an onset from January 2004 to July 2005 were investigated. 25 patients and 125 healthy asymptomatic SAT-negative villagers who also worked with ermine （control-villagers） were enrolled into this case-control study, in which activities of every step of contacting livestock and the frequency of ermine breeding tasks were compared. Results Of 302 adult villagers who bred ermine, 8.7% fit our case definition. Eighty-four percent of case-villagers bought lamb meat compared to 54% of controlvillagers（OR = 4.4, 95%CI = 1.3～16.0）. Odds ratios for washing raw lamb meat increased from 1.0 for unexposed villagers to 13.0 for villagers with exposure almost every day（X^2 = 10.95,P 〈 0.05）. Conclusions Contacting with raw lamb meat obtained from brucellosis-endemic provinces leads to brucellosis infection in breeding ermine. The existing regulations that prohibit transporting sheep from brucellosis-endemic provinces or selling sick or dead livestock must be reinforced. We advised villagers to take protective measures when handling raw meat.
