Abstract:
Objective To investigate the latest situation in the period 2006-2008 of drug resistance tuberculosis among migratory population in Chaoyang district of Beijing.Methods All sputum culture-positive specimens from migratory population were collected.Drug susceptibility of Mycobacterium tuberculosis to M,H,R and E were tested by proportion method.Results Drug susceptibility of 371 isolates from 2006-2008 were tested.Total drug resistance wag 22.4%(83/371),the primary drug resistance and the acquired drug resistance were 17.5%(58/331)and 62.5%(25/40)respectively.The multi-drug resistance was 5.9%(22/371);the primary multi-drug resistance was 4.2%(14/331)and acquired multi-drug resistance wag 20.0%(8/40).The drug resistance and multi-drug resistance were higher in treated cases than that in new cases.and the difference wag statistically significant(χ~2 was 39.020 and 13.210,P<0.01).The drug resistance to 4 anti-tuberculosis drugs from high to low was M(16.7%).H(12.1%),R(11.3%),E(1.9%).The primary drug resistance rate were 13.3%(S),8.8%(H),8.2%(R),1.8%(E).The acquired drug resistance rate were 45.5%(S),40.0%(H),37.5%(R),2.5%(E).The drug resistance to S,H and R were higher in treated cases than that in new cases,and the difference was statistically significant(χ~2 was 23.549,29.810 and 27.754,P<0.01).Conclusion The drug resistance to mycobacterium tuberculosis among migratory population was relatively high in chaoyang district of Beijing,suggesting the necessity to strength the tuberculosis control program for migratory population.
