Abstract: Objective According to the guidelines of WHO/IUATLD proposed a global drug resistance surveillance of tuberculosis project,to set up a system for surveillance of drug resistance of pulmonary tuberculosis.to obtain the result on initianl and acquired drug resistance rate of pulmonary tuberculosis in Guangdong province of China.Methods 40 centres were radomly selected,39 cases of the smear positive of pulmonary tuberculosis were intook continuously in each centre.all samples were isolated and cultured.the identification and in each centre.all samples were isolated and cultured.the identification and susceptibility test were done for the strians of culture positive.Results The frequency of initial drug resistance was 18%,acquired drug resistance was 33.7%.Conclusion The result proved that drug resistance rate is higher(18%)in Guangdong province.National TB Control Program should be strengthen.
