اهداف: باسیل کالمت-گرین (bcg) تنها واکسن در دسترس علیه بیماری سل است. سویه bcg مورد استفاده به عنوان واکسن در ایران نامشخص است. هدف این مطالعه تایید و کنترل کیفی واکسن bcg مورد استفاده در ایران و تعیین پلی مورفیسم ژنی این سویه بود. روش ها: 28 واکسن bcg لیوفلیزه (انیستیتو پاستور؛ ایران) با شماره سریال های متفاوت طی یک سال (91-1390) جمع آوری و تحت شرایط دمایی °c4 به آزمایشگاه انتقال داده شدند. از...
Tuberculosis (TB) remains a significant public health problem worldwide, but the ecology of the prevalent mycobacterial strains, and their transmission, can vary depending on country and region. Chile is a country with low incidence of TB, that has a geographically isolated location in relation to the rest of South American countries due to the Andes Mountains, but recent migration from neighbo...
Twenty Mycobacterium bovis isolates from a first reported outbreak in the Azores Islands were differentiated into four spoligotypes: SB0119 (45%), SB0121 (40%), SB1264 (10%) and SB1090 (5%) and into two MIRU-VNTR allelic profiles using eight selected loci. The isolates seem to constitute a clonal lineage from a common source of infection. The limited diversity among the analysed Azores strains ...
Tuberculosis is a leading cause of morbidity for Peruvian migrants in Florence, Italy, where they account for about 20% of yearly diagnosed cases. A retrospective study on cases notified in Peruvian residents in Florence in the period 2001-2010 was carried out and available Mycobacterium tuberculosis strains were genotyped (MIRU-VNTR-24 and Spoligotyping). One hundred thirty eight cases were re...
Mycobacterium (M.) bovis causes tuberculosis and has a broad host range, including humans, livestock, and wild animals. M. bovis infection of wild boar has been reported in several European countries. We report here the first case of M. bovis infection in a domesticated wild sow in Korea. Granulomatous and necrotizing lesions with small numbers of acid-fast bacilli were observed in nodules of t...
Random amplified polymorphism DNA (RAPD) is an easy, inexpensive technique for the characterization of pathogens in low-income countries. In this study we used RAPD to assess the genetic diversity of a small collection of isolates of mycobacteria from the Mexican state of Michoacan. In contrast with the low annual tuberculosis incidence in Michoacan relative to the national average, we found a ...
BACKGROUND Many studies using DNA fingerprinting to differentiate Mycobacterium tuberculosis (MTB) strains reveal single strains in cultures, suggesting that most disease is caused by infection with a single strain. However, recent studies using molecular epidemiological tools that amplify multiple targets have demonstrated simultaneous infection with multiple strains of MTB. We aimed to determ...
BACKGROUND An outbreak of tuberculosis occurred over a 3-year period in a medium-size community in British Columbia, Canada. The results of mycobacterial interspersed repetitive unit-variable-number tandem-repeat (MIRU-VNTR) genotyping suggested the outbreak was clonal. Traditional contact tracing did not identify a source. We used whole-genome sequencing and social-network analysis in an effor...
