چکیده

The pathogenesis of increasing drug resistance among patients with multidrug-resistant or extensively drug-resistant tuberculosis undergoing treatment is poorly understood. Increasing drug resistance found among Mycobacterium tuberculosis recovered from cavitary isolates compared with paired sputum isolates suggests pulmonary cavities may play a role in the development of worsening tuberculosis drug resistance.

Study of HIV seroprevalence in Pulmonary Tuberculosis Patients with Special Reference to Multidrug Resistant Mycobacteria

This study was planned to determine HIV seroprevalence among pulmonary tuberculosis patients, to characterize the isolated mycobacteria into typical and atypical strains and to evaluate the drug resistant pattern of mycobacterial isolates. The study aims to correlate multidrug resistance (MDR) and HIV seropositivity status in pulmonary tuberculosis patients. During the year 1994-1997, 750 pulmo...

Antituberculosis Drug Resistance in Pulmonary Isolates of Mycobacterium tuberculosis, Cuba 2012-2014.

INTRODUCTION Systematic surveillance of antituberculosis drug resistance allows identification of multidrug-resistant and extensively drug-resistant isolates of Mycobacterium tuberculosis. Surveillance studies of antituberculosis drug resistance systematically conducted in Cuba for over 15 years have revealed low circulation of multidrug-resistant tuberculosis, under 1% in new cases. OBJECTIVE ...

Extensively drug-resistant Mycobacterium tuberculosis during a trend of decreasing drug resistance from 2000 through 2006 at a Medical Center in Taiwan.

BACKGROUND Drug resistance rates are one of the most important aspects in the national tuberculosis (TB) control program, and drug-resistant TB, especially extensively drug-resistant (XDR) TB, is not well understood in Taiwan. The objectives of this study were to investigate the prevalence of drug resistance from 2000 through 2006 and to identify XDR TB isolates to elucidate the clinical charac...
