tuberculosis (tb) is an important health problem in developing countries, with varying clinical presentations depending on the organs/systems involved. to study the spectrum of clinical and paraclinical aspects of extra pulmonary tb in children suffering from pulmonary tb. this study has been carried out on 65 children with tuberculosis, admitted in tb wards of national research institute of tu...

tuberculosis (tb) is one of the most important aids associated infectious diseases worldwide. it is a leading cause of illness and death among people with hiv/aids in resource-poor areas of the world. the annual incidence of tb among indigenous iranians stands at 14 cases per 100,000 inhabitants. this study aimed to identify mycobacterium infection among iranian hiv positive patients. two sputu...

STUDY DESIGN Preliminary experimental study using a rabbit spondylitis model. PURPOSE To observe the ossification in a micro-environment containing live Mycobacterium tuberculosis transplanted with bone marrow stromal cells (BMSCs) in rabbits. OVERVIEW OF LITERATURE BMSCs differentiate to osteoblasts and then osteocytes during ossification. Mycobacterium tuberculosis does not affect BMSC gr...

PURPOSE The Mycobacterium tuberculosis complex comprises M. tuberculosis, M. bovis, M. bovis bacillus Calmette-Guérin (BCG) and M. africanum, and causes tuberculosis in humans and animals. Identification of Mycobacterium spp. and M. tuberculosis complex to the species level is important for practical use in microbiological laboratories, in addition to optimal treatment and public health. MATE...

objective: the rifampicin resistance and susceptibility of mycobacterium tuberculosis are caused by mutations in the 81-base pair region of the rpob gene encoding the b-subunit of rna polymerase. methods: isoniazid resistance of m. tuberculosis is related to mutations in inha , oxyr and ahpc genes which 30 to 90 percent of isoniazid resistance is occurred in 3015 codons of katg gene. the rpob a...

Isolates from suggestive bovine tuberculosis lesions were tested by a multiplex polymerase chain reaction (m-PCR) targeting for RvD1Rv2031c and IS6110 sequences, specific for M. bovis and Mycobacterium tuberculosis complex respectively. The m-PCR successfully identified as M. bovis 88.24% of the isolates.

Most published studies on performance characteristics of the COBAS AMPLICOR (CA) system and Real Time PCR (RT-PCR) for detection of Mycobacterium tuberculosis have been carried out in countries other than India.[1] Strains of M. tuberculosis are known to vary in their genomic structure between geographical regions. Performance characteristics of these tests have not been determined on locally p...

Nucleic acid-based amplification tests allow the rapid detection of Mycobacterium tuberculosis. Recently, a real-time PCR assay for M. tuberculosis complex, the Cobas TaqMan MTB test (Roche Diagnostics, Basel, Switzerland), was introduced. We performed a prospective study to evaluate the diagnostic performance of the Cobas TaqMan MTB test system. A total of 406 specimens collected from 247 pati...

Tuberculosis has remained to be a major public health problem in Nepal. The risk of spread of infection and emergence of drug-resistant strain has created the need for a rapid, sensitive and specific diagnostic test. In addition, clinically suspicious cases that do not give positive result in conventional laboratory test need more sensitive test for diagnosis. In order to evaluate the possibili...
