The gene polymorphism study of Mycobacterium tuberculosis in the drug-resistance surveillance and epidemi-ological survey field / 中国基层医药

ABSTRACT

Tuberculosis is a chronic infectious diseases caused by Mycobacterium tuberculosis(MTB).As the drug-resistance characteristics are different in patients with various genotypes,thus,the gene polymorphism study have critical clinical significance.Among the all kinds of techniques,some have been used to analyze polymorphism for a long time and new development in that respect has also been made recently.On the other hand,some techniques are e-merging but demonstrate promising application prospects.This study summarizes the gene polymorphism study of MTB which have been used or are emerging in recent years,and points out a few shortcomings briefly.Our object is to make a contribution to theoretical basis and knowledge accumulation in the drug-resistance and epidemiological survey field.
