特殊人群结核病的流行病学调查

为了了解某监狱犯人中结核病的患病及结核菌耐药情况，为防治提供依据，采用痰检和结核菌素试验的方式对研究对象进行普查，结核分枝杆菌采用罗氏培养，药敏试验采用比例法。结果显示，PPD试验总阳性率为60．54％。痰检发现24例患者，涂阳患病率为898．54／10万。培养菌株总耐药率为95．83％，其中初治耐药率、复治耐药率和多重耐药率分别为87．5％，100％和73．91％。提示该特殊人群结核病患病率高于一般人群。

The Investigation of Tuberculosis in Special Population

To understand the prevalence rate of tuberculosis （TB） in prisoners and Mycobacterium Tuberculosis drug resistance, to provide reference for prevention of TB. The prevalence of TB in prison was detected by sputum test and PPD test. Mycobacterium Tuberculos were been cultivated and drug resistance been tested by Proportion Method. Total positive rate of PPD test was 60.54%. 24 cases been found in prisoners, TB prevalence rate in this prison was 0. 898%. Drug resistance rate in initial treatment and re-treatment were 87. 5% and 100% respectively. Multi-drug resistance rate was 73.91%; total drug resistance rate was 95.83%. Therefore, the prevalence of TB in prison was more serious than normal population, and drug resistance of Mycobacterium Tuberculosis were also severity.
