Background and purpose: Tuberculosis is an acute/chronic, infectious and necrotizing disease involving different organs of the body, particularly the lungs. Since controlling, screening, and treatment of people infected with smear positive pulmonary tuberculosis has been highlighted in national and global objectives, this study aimed at conducting an epidemiological investigation of smear posit...
Identification of Mycobacterium tuberculosis and Rifampin Resistance in Pulmonary Extra-pulmonary Clinical Specimens Using the Gene Xpert MTB/RIF Assay
Tuberculosis is one of the most important infectious diseases. In 2009 estimate 9 million new cases were registered worldwide, mortality due tuberculosis reached 1.5 million (Markowski et al., 2011). Tuberculosis may infect any part of the body, but most commonly occurs in the lungs (known as pulmonary tuberculosis) (Dolin et al., 2010). Extra pulmonary TB occurs when tuberculosis develops outs...
BACKGROUND & OBJECTIVES As isolation of Mycobacterium tuberculosis in culture requires a long time, there is a need for simple rapid method for direct detection of M. tuberculosis from clinical specimens. Amplified nucleic acid hybridization assays such as polymerase chain reaction (PCR) have shown promising results. In the present study, the sensitivity of PCR assay was assessed over smear mic...
Background: Tuberculosis has been detected in some extra pulmonary ecological niches. Although extra pulmonary tuberculosis (EPTB) is less frequent than Pulmonary Tuberculosis (PTB), its incidence has increased worldwide. The aim of this study was to investigate the presence of EPTB and MDR-EXPT in Formalin-fixed, paraffin-embedded tissue blocks among different samples in Kerma...
Background and purpose: Tuberculosis (TB) is created by Mycobacterium tuberculosis. Application of Geographical Information System (GIS) is of great benefit in understanding the geographical pattern of TB and strengthens its control programs. This study was performed in Guilan, Iran to determine the geographical pattern of TB in this province. Materials and methods: The present ecological stu...
Background: Although infectious diseases are the most common sources for the fever of unknown origin (FUO), but the spectrum of infectious diseases is changing overtime. The purpose of the study was to define the clinical spectrum and changing the pattern of FUO.Methods: This existing data based study was undertaken from 2007 to 2011. One hundred-six patients fulfilling the modified criteria fo...
