conclusions etec and eaggec were the most detected e. coli among stool and uti samples, emphasizing the need to dedicate more health care attention to this group. in addition, our phylogenetic study may be helpful in figuring out the infection origin and for epidemiological studies. nonetheless, more research studies with larger sample sizes are suggested for confirming our results. results ove...

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...

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...

coq10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. in this study, the effect of concomitant lycopene biosynthesis on coq10 accumulation in transformed escherichia coli dh5α was studied. a lycopene production pathway including geranylgeranyl diphosphate synthase (crte), phytoene synthase (crtb), and phytoene desaturase (crti) from erwinia herbicola 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...

colibacillosis caused by avian pathogenic escherichia coli (apec) is an economic threat to the poultry industry throughout the world. some of the virulence genes may enhance the ability of e. coli isolates to grow in the tissues of broilers. the apec strains are assigned to a few distinct phylogenetic groups. the purpose of the present study was to detect the virulence genes and phylogenetic gr...

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...
