目的　了解布鲁氏菌感染状况，进一步控制布鲁氏菌病疫情。方法　采用虎红平板凝集试验（RBPT）和试管凝集试验（SAT）依据GB 15988-1995《布鲁氏菌病诊断标准及处理原则》。虎红试验为阳性，同时SAT试验1∶100（?荻）及以上者，判定布鲁氏菌血清检测阳性。结果　2007年牡丹江市疾病预防控制中心布病检测门诊共检测126人，感染率为38.89%； 以职业性接触感染率最高，感染率为48.83%，其次是食源性接触感染，感染率为21.43%；不同病因的布鲁氏菌感染率差异有统计学意义（?字2=12.06，P0.01）；血检男性93人，阳性率44.09%；女性33人，阳性率24.24%，男女间阳性率差异有统计学意义（?字2=32.27，P0.005），男性的布鲁氏菌感染率高于女性。结论　2007年牡丹江市布鲁氏菌病门诊血检阳性率高达38.89%，明显高于近年来的调查结果。应及时建立严格的牲畜检疫制度，倡导需产品接触人群来取有效的个人布病防护措施。

Analysis of the serological results for Brucella in Mudanjiang city in 2007

Objective The study was conducted to investigate the conditions of serologically confirmed Brucella infections for further control of the brucellosis epidemic. Methods The Rose Bengal plate agglutination test and tube agglutination test was conducted per GB15988-1995“ Diagnostic Criteria and Treatment Principles for Brucellosis.” A positive Brucella serological results would be confirmed by a positive Rose Bengal test result plus 1：100 （＋＋） or above in the SAT test. Results A total of 126 brucellosis patients were detected in the brucellosis clinics of CDC in Mudanjiang city in 2007, the infection rate being 38.89%. Occupational exposure was found to be the leading cause of brucellosis, the related infection rate being 48.83 percent, followed by food-borne infections, the infection rate being 21.43%. Distinguishable differences were found between various infection rates due to different causes of Brucella. （X^2= 12.06, P〈0.01）. As for the serological results, the positive rate among 93 tested men was 44.09%; the positive rate of 33 tested women was 24.24%. The positive rates between men and women were statistically different （X^2= 32.27, P〈0.005 ）, for the Brucella infection rate of men was higher than that of women. Conclusion The positive rate of Brucella infection was 38.89% based on the serological results from the Brucella clinics in Mudanjiang city in 2007, significantly higher than the results from previous investigations in recent years. The strict system for livestock quarantine should be established in time, and the individual effective protection measurement for contacts of livestock products should be sparkpluged.
