Globally, Brucella melitensis and B. abortus are the most common cause of human brucellosis. The outer membrane protein 31 (Omp31) and L7/L12 are immunodominant and protective antigens conserved in human Brucella pathogens which are considered as potential vaccine candidates. We aimed to design the fusion protein from Brucella L7/L12 and truncated Omp31proteins, in silico, clone the fusion in p...
A Brucella melitensis 16M DNA fragment of 17,119 bp, which contains a large region deleted in B. abortus strains and DNA flanking one side of the deletion, has been characterized. In addition to the previously identified omp31 gene, 14 hypothetical genes have been identified in the B. melitensis fragment, most of them showing homology to genes involved in the synthesis of a polysaccharide. Cons...
Bartonella quintana, the agent of trench fever and a cause of endocarditis and bacillary angiomatosis in humans, has the highest reported in vitro hemin requirement for any bacterium. We determined that eight membrane-associated proteins from B. quintana bind hemin and that a approximately 25-kDa protein (HbpA) was the dominant hemin-binding protein. Like many outer membrane proteins, HbpA part...
background and objectives: brucellosis is an important health problem in developing countries and no vaccine is available for the prevention of infection in humans. because of clinically infectious diseases and their economic consequences in human and animals, designing a proper vaccine against brucella is desirable. in this study, we evaluated the immune responses induced by a designed recombi...
Objective(s):Brucellosis, especially caused by Brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500,000 human cases reported annually. The commonly used live attenuated vaccine in ovine brucellosis prophylaxis is B. melitensis Rev1. But due to different problems caused by the administration of this vaccine, a protective subunit vaccine against B. me...
Brucellosis is a widespread zoonotic disease causing considerable economic and public health problems. Despite animal vaccination, brucellosis remains endemic in some areas such as Iran, especially in the western Iranian province of Hamadan. We sought to detect some of the most common virulence-associated genes in Brucella isolated from human blood cultures to determine the prevalence of some v...
مقدمه:بیماری تب مالت یا بروسلوز یک بیماری مشترک بین انسان و دام است. بروسلوز مشکل عمده بهداشت عمومی در مناطق مختلف دنیا مطرح است.با توجه به خسارات ناشی از شیوع بروسلوز ،.تشخیص به موقع و دقیق این بیماری بسیار حائز اهمیت می باشد. بنابراین شناسایی سریع بروسلا با سیستم bactec وpcr ممکن است منجر به تشخیص سریعتر و بهبود کیفیت درمان بیماران گردد. هدف ما در این مطالعه ارزیابی تکنیک pcr به عنوان یک ابزا...
زمینه: امروزه بهدلیل مشکلاتی که سوش واکسن بروسلا ملی تنسیس ایجاد میکند، توسعه واکسن ساب یونیتی با استفاده از پروتئینهای نوترکیب مد نظر است. علیرغم بهدست آمدن پروتئینهای نوترکیب با بیشتر از 95 درصد خلوص، این پروتئینها هنوز حاوی میزان زیاد و مشخصی از اندوتوکسین هستند. اندوتوکسینها، لیپوپلیساکاریدهایی همراه با غشاء بیرونی باکتریهای گرم منفی هستند. سمیت ذاتی این لیپوپلی ساکاریدها دارای ی...
