Background: The Beijing sublineage modern Mycobacterium tuberculosis strain is the most dominant strain in regards to causes of disease progression, extensive lung tissue damage, drug resistance and high outbreak rates. Methods: Mycobacterium tuberculosis isolates were obtained from Bronchoalveolar lavage patients with active pulmonary Tuberculosis before obtaining anti-tuberculosis drug treatments. The degree of severity of parenchymal lung damage is classified by the NICE Scoring System. PCR was performed on DNA extracted from bronchial lavage, using primers targeting gene TbD1. Result: 30 active pulmonary tuberculosis patients were analyzed in this study. 13 isolates of modern strains and 17 isolates of ancient strains were detected. In modern strains, 4 (30.8%) subjects had mild lung degree damage, while 9 (69.2%) subjects had severe lung damage. In ancient strains, 12 (70.6%) subjects had mild lung damage and 5 (29.4%) subjects had severe lung damage. Mycobacterium tuberculosis of modern strains correlated with the degree of lung damage, p <0.05. Odds Ratio = 5.4 CI 95% (1,12-116,99). Conclusion: In Surabaya, modern strains of Mycobacterium tuberculosis were detected in BAL of tuberculosis patients. Radiograph evaluations revealed severe lung tissue damage. The risk of severe lung damage with modern strains is 5.4 times higher than compared to ancient strains. © 2020, Institute of Medico-Legal Publications. All rights reserved.
