During a population-based study to genotype isolates of Mycobacterium tuberculosis from Buenos Aires Northern suburbs, we found isolates with molecular patterns related to those of the Beijing genotype. Five out of 590 (0.85%) patients had isolates with spoligopattern identical to that of the Beijing family. Since two of these isolates showed identical IS6110RFLP pattern, we found only four dif...
به منظور بررسی تأثیر باکتری های ازتوباکتر و سودوموناس و سطوح مختلف کود شیمیایی بر کمّیت و کیفیت علوفه شلغم علوفه ای(brassica rapa l.) آزمایشی در سال زراعی 91-1390 در مزرعه ی پژوهشی موسسه ی تحقیقات برنج کشور (رشت) در قالب طرح بلوک های کامل تصادفی با 14 تیمار و سه تکرار اجرا شد. تیمارهای آزمایشی شامل شاهد (بدون کود و بدون تلقیح)، کود کامل شیمیایی و بدون تلقیح، تلقیح با azotobacter chroococcum stra...
به منظور مطالعه اثر محلولپاشی باکتریهای محرک رشد گیاه و متابولیتهای آنها بر عملکرد کمی و کیفی برنج رقم هاشمی، آزمایشی در گلخانه دانشکده علوم کشاورزی، دانشگاه گیلان در قالب طرح بلوک کامل تصادفی در 4 تکرار در سال 1389 به اجرا درآمد. تیمارهای مورد بررسی در این تحقیق شامل سویه های مختلف باکتری محرک رشد و متابولیت های حاصل از آنها بود که عبارت بودند از: بدون محلولپاشی و بدون کود (تیمار شاهد)، بدون م...
The presence of Paramecium sexaurelia from the Paramecium aurelia complex was recorded for the first time in China (Beijing). RAPD fingerprints (band patterns) of P. sexaurelia strains, the new strain from China and others from Asia, as well as from Europe and Puerto Rico, showed polymorphism within the species as several groups of genotypes characterized by different band patterns.
We report a draft genome sequence of Mycobacterium tuberculosis strain B9741 belonging to Beijing B0/W lineage isolated from a HIV patient from Siberia, Russia. This clinical isolate showed MDR phenotype and resistance to isoniazid, rifampin, streptomycin and pyrazinamide. We analyzed SNPs associated with virulence and resistance. The draft genome sequence and annotation have been deposited at ...
Mycobacterium tuberculosis of the Bejing subtype (MtbB) is transmitted efficiently in high burden countries for this genotype. A higher virulence was associated with isolates of the "modern" Beijing genotype sub-lineages when compared to "ancient" ones. Here, we report the full genomes of the strain representing these two genotypes from Brazil, a country with a low incidence of MtbB.
The Mycobacterium tuberculosis (MTB) Beijing family isolates are geographically widespread, and there are examples of Beijing isolates that are hypervirulent and associated with drug resistance. One-fourth of Beijing genotype isolates found in Russia belong to the B0/W148 group. The aim of the present study was to investigate features of these endemic strains on a genomic level. Four Russian cl...
Resistance to isoniazid, ethambutol, and streptomycin was detected in a Mycobacterium tuberculosis strain, belonging to the Beijing family lineage, isolated from two nodule exudates of a Yorkshire terrier with generalized tuberculosis. This report alerts medical practitioners to the risk of dissemination of pre-multidrug-resistant tuberculosis (preMDR-TB) through exposure to M. tuberculosis-she...
Using geographic information system and molecular tools, we characterized a possible outbreak of tuberculosis caused by Mycobacterium tuberculosis Beijing strain in 17 patients in Cotonou, Benin, during July 2005-October 2006. Most patients lived or worked in the same area and frequented the same local drinking bar. The isolates were streptomycin resistant.
We report a draft genome sequence of Mycobacterium tuberculosis strain E186hv, belonging to the Beijing B0/W lineage and isolated from a patient from Kurgan, Russia. This clinical isolate showed a reduced virulence phenotype unusual for this lineage and resistance to isoniazid, rifampin, ethambutol, pyrazinamide, and ofloxacin. We analyzed single nucleotide polymorphisms (SNPs) associated with ...
