Pulmonary tuberculosis is a kind of disease seriously endangering human health, it is the pneumonia infection caused by mycobacterium tuberculosis
Disease.Mycobacterium tuberculosis is in latence or persistent infection state mostly after infecting human body, it can be in infection host
The intracellular defense reaction for escaping host to mass propagation and and host reach a kind of delicate balance, the infected is in life
Whenever it is likely to fall ill.Under normal circumstances, 10% the infected would develop into active tuberculosis.One without controlling
The active tuberculosis patient for the treatment of can infect 10-15 people in 1 year.
After antibiotic is by utility model and control theory lungy and technology, clinical conditions are horizontal
It is universal due to effective chemotherapeutics (isoniazid, rifampin, pyrazinamide, streptomysin, ethambutol etc.) with the progress of research
Using with BCG vaccine in worldwide popularization so that incidence lungy was once once reducing, so that people optimistically recognize
For tuberculosis the same with smallpox will be utterly destroyed by the mankind.However global tuberculosis gets damp again comprehensively since the 1990s, sends out
Sick rate is gone up again in worldwide, and WHO in 1993 announces that tuberculosis is in " global emergency state ", and is appealed " rapid
Take action and wage a struggle with tuberculosis crisis ", drug resistance and multi-drug resistance tuberculosis are great in current Tuberculosis control work
It threatens.Resistant tuberculosis refers to the mycobacterium tuberculosis in tuberculosis patient body to an a kind of line antituberculotic --- different cigarette
Drug resistance occurs for hydrazine, rifampin, ethambutol, pyrazinamide and streptomysin.And multi-drug resistance tuberculosis refers to then at least to different cigarette
Hydrazine and rifampin while drug resistance.It is multi-drug resistant since the lethal effect of isoniazid and rifampicin against Mycobacterium mycobacteria is most strong
Tuberculosis is a kind of even more serious drug resistance of tuberculosis type.
According to the statistics of the World Health Organization, tuberculosis is only after AIDS virus/AIDS, in the whole world by single biography
