Prevalence of Different Phylogenetic Clades of Mycobacterium tuberculosis in Urban and Rural Areas Bangladesh

Abstract

e341were 46 (28.2%) aboriginals, 3 (1.8%) incarcerated, and 3 (1.8%) living in a long term care facility. Forty-one (24.0%) were new patients and 83 (48.5%) had treatment failure or relapse. Exclude the new patients of our MDR program, 25 (19.8%) developed both isoniazid and rifampin resistance within one year of starting anti-tuberculosis treatment, and 81 (64.3%) developed resistance after more than two years of treatment. Drug resistance was highest against fluoroquinolone (49%).Conclusion: Having prior treatment with poor compliance was considered the major determinant of developing MDR-TB. However, 24% of our MDR-TB patients were new patients, indicating possible transmission of MDR-TB in Taiwan. Aggressive TB control efforts are needed to prevent further development and spread of MDR-TB.
