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...

BACKGROUND/AIMS Spinal tuberculosis (TB) is a common and dangerous form of extrapulmonary TB with unclear mechanisms in its occurrence and progression. This study investigated the clinical significances of bone morphogenetic protein-4 (BMP-4), osteopontin (OPN), and vitamin D receptor (VDR) gene polymorphism, mRNA and protein expression in spinal TB patients. METHODS BMP-4 and OPN gene polymo...

Background: Rifampicin resistant tuberculosis is a serious problem faced by control in China, and rapid detection of rifampicin resistance urgently needed. Objectives: This study aimed to describe the molecular characteristics frequency RNA polymerase β subunit (rpoB) gene mutations rifampicin-resistant (RR-TB) Anqing area. Methods: The rpoB fragment was amplified chain reaction (PCR), all isol...

Tuberculosis remains a major health threat and its control depends on improved measures of prevention, diagnosis and treatment. Biosignatures can play a significant role in the development of novel intervention measures against TB and blood transcriptional profiling is increasingly exploited for their rational design. Such profiles also reveal fundamental biological mechanisms associated with t...

This study aims to evaluate the clinical value of PCR-fluorescent probes for detecting mutation gene associated with extensively drug-resistant tuberculosis (XDR-TB). The molecular species identification 900 sputum specimens was performed using polymerase chain reaction (PCR)–fluorescent probe. mutations drug resistance genes rpoB, katG, inhA, embB, rpsL, rrs, and gyrA were detected. convention...

TB) is still a major problem globally Background: Mycobacterium tuberculosis and especially in Africa. Vitamin D deficiency has been linked to TB in the past and studies have found vitamin D deficiency to be common among Ugandan TB patients. The functional activity of vitamin D is dependent on the genotype of the vitamin D receptor (VDR) polymorphic genes. Recent findings have indicated that VD...

BACKGROUND Polymorphisms in the gene that encodes the vitamin D receptor (VDR) may influence the host response to Mycobacterium tuberculosis infection. METHODS In a Peruvian community with a high incidence of tuberculosis (TB), VDR TaqI and FokI polymorphisms were compared among 103 patients with pulmonary TB and 206 matched healthy control subjects. Associations of VDR polymorphisms with tre...

Fe-deficiency anaemia is the most common cause of anaemia in developing countries. In these settings, many chronic infections, including tuberculosis (TB), are highly prevalent. Fe is an essential nutrient for both host and mycobacteria that play a pivotal role in host immunity and mycobacterial growth. A case-control study was performed in a TB-endemic region in Jakarta, Indonesia, among 378 p...

Methods TB & HIV infection in children in retrospective study was in our mind. WHO endorsed in 2010 new diagnostic tool to confirm TB, like Gene XPRT, MDR/RIP, PCR based test even in children. Presently it is not widely available in Sub Saharan Africa because of high cost. South Africa lucky to have Gene XPRT test kit available even in district hospital. BCG vaccine and Tuberculin skin test and...
