بررسی مولکولی سویه مایکوباکتریوم های جدا شده از ترشحات لنفاوی کودکان مبتلا به لنفادنیت ناشی از واکسیناسیون با واکسن BCG
Background and Aim: In Iran vaccination with Bacillus Calmette-Guérin (BCG) is performed on all newborns within the first days of life for prevention of tuberculosis. It is a live attenuated vaccine and produced from genetically different vaccine strains of Mycobacterium bovis. This vaccine is safe but local adverse reactions such as administration site abscess and lymphadenitis occur in some h...
متن کاملLoss of Lipid Virulence Factors Reduces the Efficacy of the BCG Vaccine
Bacille Calmette-Guérin (BCG), an attenuated strain of Mycobacterium bovis, is the only vaccine available for tuberculosis (TB) control. BCG comprises a number of substrains that exhibit genetic and biochemical differences. Whether and how these differences affect BCG efficacy remain unknown. Compared to other BCG strains, BCG-Japan, -Moreau, and -Glaxo are defective in the production of phthio...
متن کاملVariable Virulence and Efficacy of BCG Vaccine Strains in Mice and Correlation With Genome Polymorphisms.
Bacille Calmette-Guérin (BCG), an attenuated strain of Mycobacterium bovis, is the only vaccine available for tuberculosis (TB) control. However, BCG is not an ideal vaccine and has two major limitations: BCG exhibits highly variable effectiveness against the development of TB both in pediatric and adult populations and can cause disseminated BCG disease in immunocompromised individuals. BCG co...
متن کاملبثژ تنها واکسن موجود جهت مقابله با بیماری سل: مقاله مروری
Background: Despite advances in the vaccinology and chemotherapy in the past century, tuberculosis is still responsible for two million deaths every year. Emergence of multi-drug resistant strain and coinfection of TB-HIV make it a serious concern. Treatment and control of tuberculosis is a great health burden in every community. Active tuberculosis in children has very severe consequences espe...
متن کاملThe Genetic Regulation of Infant Immune Responses to Vaccination
A number of factors are recognized to influence immune responses to vaccinations including age, gender, the dose, and quality of the antigen used, the number of doses given, the route of administration, and the nutritional status of the recipient. Additionally, several immunogenetic studies have identified associations between polymorphisms in genes encoding immune response proteins, both innat...
