A polymerase chain reaction (PCR) assay targeted to the immunogenic protein MPB64 gene was used to detect members of the Mycobacterium tuberculosis complex, and an outward-primed PCR (OPPCR) designed on the IS6110 element allowed differentiation between Mycobacterium bovis and Mycobacterium tuberculosis. Additionally, the amplification of IS1110 and 16S ribosomal RNA sequences combined with a d...
human t-cell lymphotropic virus type 1 , 2 (htlv-1, 2) is endemic in particular areas of the world in which it is associated with myeloid leukemia.in this study, we described the prevalence of htlv-1, 2 in myeloid leukemia and mycobacterium tuberculosis in iran. we have worked with tissue and blood samples for 2 years. these were the same samples which were positive for myeloid leukemia, mycoba...
Introduction: Tuberculosis is a communicable disease caused by mycobacterium tuberculosis that primarily affects the lungs. Primary tuberculosis of the nose in the pediatric age group is rare. The diagnosis of this common entity in the present case was challenging. Case Report: We report the case of a 3-year old girl who presented with a painless swelling over the dorsum of the nose for 7 mon...
Abstract Mycobacterium genus, including pathogenic and environmental species, is called non-tuberculosis mycobacteria. In this review, we assessed the research about the frequency of non-tuberculosis mycobacteria in Iran. The analyses showed that there are 16 and 28 mycobacterial species isolated in water and soil samples, respectively. The most frequent mycobacterial species in water were M. f...
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 & Aims: Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), remain as a leading causes of mortality among infectious diseases. The only current vaccine, bacillus Calmette-Gue´rin (BCG), displays highly variable efficiency for preventing tuberculosis. Thus, identification of protective antigens could be mentioned for designing new vaccines. Among different Mtb antigens,...
Introduction: Among several tuberculosis vaccine candidates for replacement of BCG, ESAT-6 protein has a special role. Since mycobacterium tuberculosis infection most often attacks the lungs, intranasal rout can be regarded as appropriate methods for tuberculosis vaccines and drug delivery. One of the appropriate systems for intranasal vaccine delivery is using biodegradable nanoparticles. Amon...
Background and Objective: Tuberculosis (TB) caused by Mycobacterium tuberculosis, is an infectious disease in human which kills nearly three millions of people annually. Approximately, one - third of the world populations are infected with this bacteria and 5 - 10 % of them develop the active form of the disease. Individuals are different in susceptibility to TB infection. These differences mig...
Genetic assessment by spoligotyping of 565 Mycobacterium tuberculosis complex strains collected from the Western Region of Cameroon between 2004 and 2005 has confirmed the establishment of the "Cameroon family" as the leading cause of tuberculosis in 45.9% of cases and evidenced the rapid quasi extinction of Mycobacterium africanum, isolated in 3.3% of tuberculosis cases.
QuantiFERON-TB Gold In-Tube (QFT-GIT) and tuberculin skin test (TST) results are reported in 23 children with active tuberculosis due to Mycobacterium tuberculosis and Mycobacterium bovis. Overall QFT-GIT (96%) was more sensitive than TST (74%) for detecting tuberculosis infection in these patients.
