● Project Background:
One third of the world's population (about 2 billion people) are infected with TB. There are 20 million people living with TB worldwide, and about 8-10 million new cases are detected each year. China is one of the 22 countries with high burden of tuberculosis in the world. The patients who die of tuberculosis reach 1.3 million every year, ranking the second place of class A and B infectious diseases. At the same time, the annual incidence of tuberculosis in China is estimated to be at least 5 million people, also ranking second in class A and B infectious diseases. The source of transmission of tuberculosis is mainly Mycobacterium tuberculosis in the sputum or droplets of tuberculosis patients. This kind of tuberculosis is called infectious tuberculosis or open tuberculosis. The public's awareness of tuberculosis protection is still generally low, so it is particularly necessary to take the initiative to carry out the screening of tuberculosis.
Pony Medical ensures that each test result is more accurate and better serves the majority of patients.
●Meaning of nontuberculous mycobacteria:
Nontuberculous mycobacteria are mycobacteria other than Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium leprae. Formerly known as atypical mycobacteria, its characteristics are different from those of Mycobacterium tuberculosis, such as more sensitive to acids and bases; They were tolerant to commonly used anti-tuberculosis drugs. The growth temperature of Mycobacterium tuberculosis was not as strict as that of Mycobacterium tuberculosis. They are mostly found in the environment. It is an opportunistic pathogen. It is of concern because it causes tuberculosis-like lesions.
In recent years, nucleic acid amplification technology has provided great convenience for the detection of mycobacteria, which can reduce the diagnosis time from weeks to days or even hours. And can fully ensure the stability and repeatability of detection.
