nanotechnology is a new and specific method for therapy of diseases. nanosilver particle is one of the functional fields of nanotechnology. it has been shown that these nanoparticles have antibacterial and antifungal properties. different studied have been shown that nanoparticles may have important role in medicine. for example, it has been shown to have inhibitory effects on the treatment of ...

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...

background and objectives: urinary tract infection (uti) is one of the most common infections in human, and uropathogenic escherichia coli (upec) strains are the most common cause of uti. these strains colonize in bladder and cause cystitis, which could cause pyelonephritis by movement to the kidneys. since fimh protein has a very important role in colonization of upec strains and causing infec...

background and objectives: diarrheagenic escherichia coli (dec) is an emerging agent among pathogens that causes diarrhea. studies showed that diarrheagenic e. coli such as enterohaemorrhagic e. coli (ehec), enteroaggregative e. coli (eaec), enteropathogenic e. coli (epec), enteroinvasive e. coli (eiec), enterotoxigenic e. coli (etec), diffusely adhering e. coli (daec) and shiga toxin producing...

background and objectives: diarrhea is one of the most prevalent diseases in the world, specially in developing countries. one of the most important causative agents of bacterial diarrhea is diarrheagenic escherichia coli (dec) which causes gastroenteritis and this group involving enterotoxigenic e. coli (etec), enteropathogenic e. coli (epec), enteroaggregative e. coli (eaec), enterohemoragic ...

background: extended spectrum beta lactamases (esbls) are an important cause of transferable multidrug resistance (mdr) in gram-negative bacteria. the most described esbl genes are generally found within integron-like structures as mobile genetic elements. the aim of this study was to identify the accompanying of class 1 integrons and esbls in the mdr e. coli isolates. methods: susceptibility t...

Background: Shiga toxin-producing Escherichia coli (STEC) are group of E. coli causing bloody diarrhea. The goal of this survey was to determine the prevalence of multidrug resistant shiga toxin-producing E. coli in cattle meat and its contact surfaces. Methods: Swab samples (n=120) were randomly collected from meat and contact surface of butchery shops in Sharkia province, Egypt. Prevalence o...
