Type 1 secretion systems (T1SS) of Gram-negative bacteria secrete a broad range of substrates into the extracellular space. Common to all substrates is a C-terminal secretion sequence and nonapeptide repeats in the C-terminal part that bind Ca(2+) in the extracellular space, to trigger protein folding. Like all T1SS, the hemolysin A (HlyA) T1SS of Escherichia coli consists of an ABC transporter...

Introduction: E. coli is the predominant causes of urinary tract infection. Several virulence factors for bacterial infections in the urinary tract are required. In this study, we have considered several virulence factors in strains isolated from the patients with UTI in Yazd. Methods: In this cross-sectional study in 1394-1395, 146 strains isolated were collected from the patients with urinar...

زمینه و هدف: کلبسیلا پنومونیه که باعث عفونت ­های دستگاه گردش خون و ادرار می­شود حاوی چندین ژن کدکنندۀ عوامل بیمار ی ­زا است. عواملی مثل توانایی اتصال به سطوح˛ وجود گیرنده­های سیدروفور˛ سیستم جذب آهن و تنظیم فنوتیپ مخاطی جزء اساسی­ ترین فاکتورهای دخیل در ایجاد بیماری از سوی کلبسیلا پنومونیه هستند. این مطالعه با هدف تعیین میزان حضور ژن­های کدکنندۀ این فاکتورهای بیماری­ زا در کلبسیلا پنومونیۀ جداش...

Background and Objective: Klebsiella pneumoniae is known as one of the opportunistic pathogens. The prevalence of antibiotic resistance, emergence of multidrug resistant strains, and multiple virulence factors contribute to the development of various infections. In this regard, the aim of this study was to evaluate the frequency of fimH, magA, and rmpA genes among Klebsiella pneumoniae isolates...

Urinary tract infections (UTIs) are one of main health problems caused by many microorganisms, including uropathogenic Escherichia coli (UPEC). The virulence factors important in colonization UPEC, extra-intestinal survival, and creation cytopathic effects. In addition, the expression special UPEC can contribute to uropathogenicity, as well worsening UTIs. this study, 134 isolates E. were colle...

Urinary tract infections (UTI) caused primarily by uropathogenic Escherichia coli (UPEC) are indeed an extremely contagious disease that affects people all over the world. FimH is a major virulence component in UTI pathogenesis, and inhibiting function can be efficient means to disarm UPEC bacteria, as well crucial target development of non-antibiotic mediated treatment options. The goal this s...

کلبسیلا پنومونیا یک پاتوژن مهم بیمارستانی است که اغلب باعث پنومونی و عفونت های خونی یا دستگاه ادراری می شود. این سویه ها فاکتورهای ویرولانس مهمی از جمله کپسول پلی ساکاریدی، آدهسین ها، سیدروفورها و توکسین ها را حمل می کنند که به پیشرفت عفونت های آن کمک می کند. اولین قدم برای مقابله و مهار این پاتوژن شناسایی فاکتورهای مهم ویرلانس آن است. هدف اصلی این پژوهش تعیین فراوانی ژن های کد کننده فاکتورهای ...
