肺结核是由结核分枝杆菌感染而引起的慢性肺部疾病,目前仍是我国的一项重大公共卫生问题[1-2]。根据“全球结核控制投资的经济效益”的一项研究,在全球22个结核病高负担国家中中国居第二位[3]。近年来,由于农民工大量进城,加之居住环境差、生活水平低、体力劳动重以及耐药结核患者增加等因素,我国肺结核的发病率和病死率均有逐年增加的趋势。临床上以找到结核杆菌为诊断的金标准,因而通过细菌学确诊活动性肺结核患者变得越来越重要。在能够
Tuberculosis is a chronic lung disease caused by Mycobacterium tuberculosis infection and is still a major public health problem in our country. [1-2] According to a study entitled “Economic Benefits of Global TB Control Investment,” China ranks second in 22 countries with high TB burden in the world [3]. In recent years, as a large number of migrant workers into the city, combined with poor living conditions, low living standards, heavy physical and drug-resistant tuberculosis patients increased and other factors, the incidence of tuberculosis and mortality in China have increased year by year trend.
