【摘要】：結核病(Tuberculosis，TB)一直是嚴重威脅人類健康的以呼吸系統(tǒng)感染為主的慢性傳染性疾病，其病原菌是結核分枝桿菌(Mycobacteriumtuberculosis，MTB)。隨著AIDS的蔓延，原來曾被人類控制并有望在發(fā)達國家消失的結核病，其發(fā)病率和死亡率在許多國家和地區(qū)出現(xiàn)上升的趨勢。在過去的十年中，結核病成為人類死亡的重要原因。WHO報道，全球近三分之一的人已感染結核菌，每年有約八百萬新結核病人出現(xiàn)，死亡的人數(shù)達兩百萬人，如果結核菌感染得不到有效控制的話，從2002年到2020年，，又將有10億人感染結核菌。我國是世界上22個結核病高發(fā)國家之一，結核病人數(shù)居世界第二位，形勢嚴峻。這可能是由于人類免疫缺陷病毒(HIV)在全世界范圍的傳播，引起艾滋病的廣泛流行，機體免疫力下降甚至缺陷，進而導致結核病的流行。全球范圍的移民和人口流動使結核菌傳播范圍進一步擴大。再加上90％結核菌感染者為隱匿感染，阻礙了結核病的防治。結核菌診斷的金標準是結核菌的培養(yǎng)，而其生長緩慢，如何使MTB快速生長成為研究熱點之一。因此積極深入研究結核病的發(fā)病機制，找出更加有效的診斷、治療和預防結核病的新技術、新方法和新疫苗具有深遠的意義。
[Abstract]:Tuberculosis (TB) is a chronic infectious disease which is a serious threat to human health. The main pathogen of tuberculosis is Mycobacterium tuberculosis (MTB). With the spread of AIDS, tuberculosis, once controlled by human beings and expected to disappear in developed countries, has an increasing trend of morbidity and mortality in many countries and regions. In the past decade, tuberculosis has become an important cause of human death. The WHO reports that nearly 1/3 people worldwide have been infected with TB, and about 8 million new TB patients appear each year, with 2 million deaths. If TB infection is not effectively controlled, another 1 billion people will be infected between 2002 and 2020. China is one of the 22 countries with high incidence of tuberculosis. This may be due to the spread of human immunodeficiency virus (HIV) in the world, causing the widespread spread of AIDS, the decline of immunity and even the deficiency of the body, which leads to the prevalence of tuberculosis. Worldwide migration and population mobility have further expanded the spread of tuberculous bacteria. In addition, 90% of TB infection is concealed infection, which hinders the prevention and treatment of tuberculosis. The gold standard for the diagnosis of tuberculous bacteria is the culture of tuberculous bacteria, but its growth is slow. How to make the rapid growth of MTB become one of the research hotspots. Therefore, it is of great significance to study the pathogenesis of tuberculosis, find out more effective diagnosis, treatment and prevention of tuberculosis new technology, new methods and new vaccines.
