Background: Data on the clinical characteristics of delayed treatment initiation among pulmonary tuberculosis (TB) patients are lacking. Thus, this study aimed to identify factors associated with in culture-confirmed TB and assess outcomes treatment.

Background Epidemiological information on tuberculosis (TB) is required to plan control and prevention strategies and to inform service delivery systems. The aim of present study was to determine the epidemiological status of TB in Hamadan Province covering a seven-year period.   Methods In this cross-sectional study all registered TB patients suffering from any form of smear-positive, smear-ne...

background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...

Background Mycobacterium tuberculosis and HIV act synergistically to enhance and accelerate the development of tuberculosis and progression of HIV infection to AIDS. Hematogenous dissemination of M. tuberculosis leading to extrapulmonary TB, disseminated TB and miliary TB is greatly increased in HIV+ TB patients. We have compared the transcriptome of M. tuberculosis replicating in whole blood f...
