بیماری های ناشی از مصرف غذاهای آلوده به باکتری های عامل فساد و بیماری زا به طور مستقیم در سلامت جامعه نقش دارد. پپتیدهای ضدمیکروبی از جمله هموپلیمرهای کاتیونی مانند پلی-ال-لیزین و ترکیبات غنی از آرژینین مانند پروتامین برای کنترل میکروب ها اخیراً به عنوان یک روش جدید کنترل میکروبی در صنایع غذایی مورد استفاده قرار می گیرند. فعالیت ضدمیکروبی پلی-ال-آرژینین به عنوان یک پپتید ضدمیکروبی کاتیونی کمتر م...
This study was carried out to determine the prevalence of foodborne pathogens, Escherichia coli, E. coli O157:H7, Listeria monocytogenes and Campylobacter spp. on slaughtered cattle in Isfahan, Iran. A total of 203 cattle carcasses were sampled by surface section of neck meat taken immediately after slaughter and analyzed using microbiological examinations. Suspected colonies to E. coli O157:H7...
Enterohemorrhagic Escherichia coli (EHEC) of the O157:H7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human EHEC disease. The aim of the present study was to investigate the prevalence of E. coli O157: H7/NM in raw meat samples from two provinces of Iran. During a period from March 2010 to March 2011. Two hundred and ninety five raw meat samples were...

Abstract Background and Objective: Escherichia coli O157:H7 is one of the most well-known pathogenic bacteria worldwide that can develop severe diseases such as hemolytic uremic syndrome (HUS). This study aimed to assess the prevalence of virulence genes of E. coli O157:H7 in patients with suspected urinary tract infections (UTIs). Material and Methods: This cross-sectional study was co...
enterohemorrhagic escherichia coli (ehec) of the o157:h7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human ehec disease. the aim of the present study was to investigate the prevalence of e. coli o157: h7/nm in raw meat samples from two provinces of iran. during a period from march 2010 to march 2011. two hundred and ninety five raw meat samples were...
Enterohemorrhagic Escherichia coli (EHEC), such as E. coli O157:H7, are emerging food-borne pathogens worldwide. This micro-organism can damage the epithelial tissue of the large intestine. The cytotoxic effects can be neutralized by probiotics such as Bifidobacterium bifidum. Probiotics are viable cells that have beneficial effects on the health of the host. The preventing activity of B. bifid...
اشریشیاکلی سویه o157:h7 یکی از مهمترین پاتوژن های غذایی تولید کننده بیماری کولیت خونریزی دهنده و ادرار خونی در انسان می باشد. دام های اهلی اصلی ترین مخزن این باکتری بوده و بکارگیری واکسن بر علیه آن یکی از مهمترین را ههای پیشگیری این باکتری می باشد. پروتئین های intimin، tir و espa مهمترین فاکتورهای بیماریزایی این باکتری به حساب می آیند که توسط ژن های حاضر در جزیره پاتوژنسیته lee تولید می شوند....
This study was conducted to investigate the presence of Escherichia (E.) coli O157 and E. coli O157:H7 and stx1 and stx2 genes on cattle carcasses and in rectal samples collected from Samsun Province of Turkey. A total of 200 samples collected from cattle carcasses and the rectal contents of 100 slaughtered cattle from two commercial abattoirs were tested using the immunomagnetic separation tec...
