familial adenomatous polyposis (fap) is a hereditary autosomal dominant cancer syndrome, results from germ line mutation or deletion of the adenomatous polyposis coli (apc) gene on chromosome 5q21. patients with fap suffer from multiple polyps mainly at the colorectal region as well as other parts of the gastrointestinal tract, which has propensity to transform into carcinoma. fap has also been...

background: escherichia coli is one of the most important pathogens which could be transmitted by milk. the main aim of the present study was to assess risk factors related to the occurrence of e. coli in fluid milk marketed in chittagong, bangladesh. methods: totally, 169 milk samples were collected from different entry points in chittagong, bangladesh; and also, 17 samples were directly colle...

the aim of this study was to evaluate the effect of walnut tree root (juglandaceae) on escherichia coli is resistant to various antibiotics. walnut tree root extract was obtained using a rotary device. 20 cases of e. coli was obtained from urinary tract infections zabul hospital and mic and mbc were determined using dilution in the wells. the results of the study showed that the concentrations ...

in this study, 90 internal organ samples of poultry with symptoms of colibacillosis were obtained from maragheh poultry farms in east azerbaijan, iran. in total, 70 bacterial isolates were confirmed as escherichia coli (e. coli) strains using standard biochemical tests, and antibiotic sensitivity was determined by the disk diffusion method. antibiotics used in this study included ampicillin, pe...

objective(s): enterotoxigenic escherichia coli (etec) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. igy technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. the purpose of this study was to produce specific antibody by egg yolk antibody (igy...

background: uropathogenic escherichia coli (upec) are major bacterial agent of urinary tract infection (uti). this infection is more prevalent among women because approximately half of all women will experience a uti in their life-time and near a quarter of them will have a recurrent infection within 6–12 months. iuta protein has a major role during upec pathogenesis and consequently infection....

background and objectives: the most common serotype of enterohaemorrhagic esherichia coli group or shiga-toxin-producing e. coli is o157:h7. domestic and wild ruminants are regarded as the main natural reservoirs. o157:h7 serotype is the major cause of gastrointestinal infections in developed countries. in this study was conducted to survey on the toxigenic e. coli o157: h7 strains in milk of i...

background and objectives: auto-induction is usually employed to achieve high cell density and overproduction of proteins with a simple and low-cost operation. the efficiency of heterologous protein expression in escherichia coli is determined by different parameters. interactions between these parameters usually complicate the identification of those that contribute more to the improvement of ...

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...
