Low Occurrence of Tuberculosis Drug Resistance among Pulmonary Tuberculosis Patients froman Urban Setting, with a Long-Running DOTS Programin Zambia

We set out to determine the levels of Mycobacterium tuberculosis resistance to first- and second-line TB drugs in an urban population in Zambia. Sputum samples were collected consecutively from all smear-positive, new and previously treated patients, from four diagnostic centres in Ndola between January and July 2006. Drug susceptibility testing was performed using the proportion method against four first- and two second-line TB drugs. Results. Among 156 new cases, any resistance was observed to be 7.7%, monoresistance to isoniazid and rifampicin was 4.5% and 1.3%, respectively. Of 31 retreatment cases, any resistance was observed to be 16.1%, monoresistance to isoniazid and rifampicin was 3.3% for. | Hindawi Publishing Corporation Tuberculosis Research and Treatment Volume 2010 Article ID 938178 6 pages doi 10.1155 2010 938178 Research Article Low Occurrence of Tuberculosis Drug Resistance among Pulmonary Tuberculosis Patients from an Urban Setting with a Long-Running DOTS Program in Zambia Chanda Mulenga 1 2 Allan Chonde 1 Innocent C.
