The nationwide tuberculosis drug resistance survey in Mongolia, 1999.

Setting: Mongolia, a country in the Western Pacific Region burdened with many cases of tuberculosis, with rapid expansion of DOTS over the last several years.

Objective: To determine the prevalence of resistance to major anti-tuberculosis drugs among tuberculosis patients who have never been treated previously.

Design: Sputum specimens were collected from all smear-positive tuberculosis patients identified from 1 November 1998 to 1 May 1999.

DOTS (Directly Observed Treatment Strategy) project in Mongolia, 1995.

Objective: To establish a tuberculosis (TB) control programme consistent with recommendations made by the WHO and the International Union Against Tuberculosis and Lung Disease (IUATLD) in a country where, as in control programmes of the former USSR, TB management previously relied on active case-finding with radiology and long-term monitoring and treatment of patients.

Design And Methods: A pilot DOTS strategy (directly observed treatment, short course) project was implemented in Dornod Aimak, Eastern Mongolia During a 6-week period, individuals with chronic cough of > or =3 weeks were screened with sputum smear microscopy. Smear-positive patients received a supervised 6-month regimen (2SRHZ/4RH).

Clinical characteristics differentiating bacteriologically positive pulmonary tuberculosis patients from negative ones in Mongolia.

The objective of this study is to clarify clinical characteristics which differentiate bacteriologically positive pulmonary tuberculosis patients from negative ones in Mongolia. The subjects include 338 patients aged 16 years and older who had undergone bacteriological examinations. Of them, 107 patients (31.
