Abstract
Objectives:
- Survey on detection and drug resistance rate of Mycobacterium tuberculosis isolated at Hue Central Hospital by Ziehl-Neelsen staining and culture methods.
Methods:
We performed a cross-sectional study. From 1/2008 to 12/2009, the specimens of patients with the diagnostic pulmonary and extra-pulmonary tuberculosis at Hue Central Hospital were examined for smear examination, culture, and Mycobacterium tuberculosis identification.
Results:
- Smears examined by microscopy were positive for AFB in 5.5% (432*/7891) and culture for M. tuberculosis in 12.9% (310*/2399).
- The positive rate was higher among sputum, bronchial aspirate than among other specimens.
- The ratio of strains of bacteria isolated from sputum was highest (88.4%).
- The majority of positive culture patients were in the age group 25-54.
- It was also higher in rural areas than in urban areas.
- The rate of drug resistance of 103 tuberculosis strains isolated was 16.5%.
- The rate of MDR-TB was 5.8%.
