Clinical impact of Mycobacterium tuberculosis W-Beijing genotype strain infection on aged patients in Taiwan.

چکیده
The impact of W-Beijing genotype Mycobacterium tuberculosis on treatment outcome was evaluated in 249 newly diagnosed tuberculosis patients. No significant difference in the treatment outcome was found between the W-Beijing and non-W-Beijing groups. However, a poor outcome was more common in the elderly patients (>or=65 years) infected with the W-Beijing strain.
