conclusions the results of this study indicated that more than 90% of e. coli isolates harbored the fimh gene. the high binding ability of fimh could result in the increased pathogenicity of e. coli; thus, fimh could be used as a possible diagnostic marker and/or vaccine candidate. materials and methods a total of 140 isolated e. coli strains from patients with uti were identified using biochem...

conclusions it can be concluded that the rsm is an effective method for the optimization of recombinant protein expression using synthetic genes in e. coli. results the proposed optimum fermentation condition consisted of 7.81 g l-1 glucose, od 600 nm prior induction 1.66 and induction temperature of 30.27°c. the model prediction of 0.267 g l-1 of rhifn-β and 0.961 g l-1 of acetate at the optim...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...

b ackground: in recent decades, extended spectrum beta-lactamase (esbl) producing bacteria have increased worldwide. the most important causative agents of nosocomial infections throughout the world, escherichia coli and klebsiella pneumoniae as main esbl-producing bacteria are so highly regarded. trends  in  the  treatment  of  infections  by such  bacteria  have  led  to  a  global concern. t...

background: introduction: enterotoxigenic escherichia coli (etec) is the most important bacterial cause of watery  travelers' diarrhea  in  developing countries. watery diarrhea is can cause serious life-threatening dehydration. etec was caused diarrhea by the secretion of two heat-labile enterotoxins (lts) and the heat-stable enterotoxins (sts) which increase intestinal secretion. routine labo...

shiga toxin producing escherichia coli have been associated with hus, hc and ttp in human. we found recto-anal mucosal sample in sheep as well in cattle is the main site for e. coli o157 localization. 1246 e. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of shiga toxin-producing (vt 1 and vt 2) and intimin (eae) genes used multiplex pcr. ...

in this study, to know about the phylogeny of escherichia coli isolated from broilers with collibacillosis in tabriz, 70 e. coli isolates recovered from broilers with collibacillosis were characterized for phylogenetic group (a, b1, b2, d) by multiplex pcr. of the all 70 samples, 35 (50%) isolates were classified as type a, 32 (45%) as type d, 2 (2.8%) as type b1 and 1 (2.8%) as type b2. thi...

familial adenomatous polyposis (fap) is responsible for < 1% of colorectal cancer (crc) cases and is inherited as an autosomal dominant trait. patients generally present hundreds to thousands of adenomas and develop colorectal cancer by age 35- 40 if left untreated. here we report four patients with germline frameshift mutation (small deletion) at exon 15 of adenomatous polyposis coli (apc) tum...

escherichia coli (e. coli) bacteria can damage dna of the gut lining cells and may encourage the development of colon cancer according to recent reports. genetic switches are specific sequence motifs and many of them are drug targets. it is interesting to know motifs and their location in sequences. at the present study, gibbs sampler algorithm was used in order to predict and find functional m...

the aim of this study was to isolate escherichia coli from chickens and to determine the presence of the eaea gene, a virulence factor detected in escherichia coli, in the isolates by polymerase chain reaction (pcr). different chicken organs (lung, liver and spleen) were inoculated onto blood agar and biochemical tests were performed on the suspicious isolates. escherichiacoliwas isolated from ...
