陕西省1406份布鲁杆菌病高危职业人群血清学检测报告分析

Analysis on 1406 Serological Detection Reports of Brucellosis among High Risk Group in Shanxi Province

目的通过对陕西省布鲁杆菌病(简称布病)高危职业人群血清检验结果分析,了解布病感染现况。方法根据《陕西省布病监测方案》和《西安布病监测实施方案》要求开展监测,结果判定依据GB15988-1995。结果采集布病血清累计1406份,以省级监测点最多(953份,69.78%),琥红平板凝集试验(RBPT)检测阳性率达4.69%,不同人群RBPT检测阳性率波动在1.99%～18.92%间,以暴发疫点最高,达18.92%;市级监测点为6.23%,省级监测点为1.99%,经χ2检验,差异有统计学意义(χ2=83.9382,v=2,P<0.01)。试管凝集试验(SAT)检测阳性率达39.39%,阳性率波动在26.32%～53.57%之间,以暴发疫点最高,其次为省级监测点和市级监测点,χ2检验差异无统计学意义(χ2=4.2042,v=2,P>0.05)。依据国家标准判定感染者12例,隐性感染和确诊病例各7例,不同感染类型间差异无统计学意义(χ2=6.1100,v=4,P>0.05)。结论监测县血清检验符合率不高的原因与实验中缺乏对照、实验条件控制不好。

[ Objective ] To understand infectious situation of Brucellosis through analysis of Brucellosis high risk group＇s serological detection results. [ Methods] The monitoring was carried on according to ＂ Shaanxi Brucellosis monitoring program＂ and ＂ Xi＇an Brucellosis monitoring and implementation program＂ ; results were determined based on GB 15988-1995. [ Results] A total of 1406 samples of Brucellosis serum were collected, with a maximum in monitoring spots of provincial level （ 953 samples, 69.78% ）, posi- tive rate in PBPT detection was 4.69%, fluctuations of the positive RBPT rate between different groups were from 1.99% to 18.92 % ; the positive rate in monitoring spots of city-level was 6.23%, 1.99% in provincial level, the difference was significant based onX2 test （ X2 = 83. 9382,v = 2, P 〈 0.01 ）. Positive rate in SAT test was 39.39% with fluctuations from 26.32% to 53. 57%. Outbreak focus took the first place, followed by monitoring spots of provincial level and city-level, the difference was not sig- nificant based onX2 test （ X2 = 4. 2042,v = 2, P 〉 0. 05 ）. 12 infectors were judged by national standards, 7 hidden infectors and 7 confirmed cases were found, difference between different types of infection was not significant（ X2 =6. 1100,v =4, P 〉0.01 ）. [ Conclusion] The coincidence rate of serum examinations in monitoring county is not high; it is related with Lack of control in experiments, poor control of experimental conditions, and no quality control test.
