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

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X2检验，差异有统计学意义（X2=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，X2检验差异无统计学意义（X2=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（X2=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、未开展实验质控等原因有关

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

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.
