Background: Crohn's disease and Ulcerative colitis are known as inflammatory bowel disease with high morbidity which are as a result of increasing immune responses to intestinal microbiota in genetically susceptible individuals. The association of adherent invasive Escherichia coli with Crohn's disease in human has been discussed for decades. The principal aim of this study was to assess the re...

conclusions this study suggests that epec strains are important contributors to diarrhea in iranian children. because of the weakness of routine microbiological tests and poor specifity of serological tests, it is recommended that the epec strains are better detected by molecular methods. results the e. coli isolates were confirmed by the presence of the uida gene. the epec was diagnosed in 6 c...

diarrhea is an important hygienic problem in under development countries. among pathogenic agents escherichia coli is the most etiologic agent of diarrhea in children below five years old. some e. coli strains produce cytotoxins that have cytopathic effect on vero cell and identified as verotoxin. this study performs for resolve frequency of vero toxigenic escherichia coli (vtec) in kerman city...

conclusions overall, except for pcvd432 and aggr, we detected high heterogeneity of virulence factors among eaec isolates causing diarrhea in children. one set of genes, in the combination, pic- sepa- agg4a, was associated with strong biofilm. results among the 322 e. coli isolated, 23 were identified as eaec. all eaec carried a 630-bp fragment of the plasmid (paa) encoded pcvd432 and aggr gene...

introduction : toxoplasmosis is a parasitic infection caused by the protozoan toxoplasma gondii it leads to serious medical problems in congenitally-infected and immunocompromised individuals, while it is quite harmless in immunocompetent individuals. toxoplasma tissue cyst matrix protein (mag1) induces early humoral and cell-mediated immune responses. previous studies suggested recombinant mag...

introduction: escherichia coli is one of the important pathogens in human with global importance. because of the necessity for identification and the use of novel antibacterial compounds against e. coli , in this present study we focused on the antibacterial effects of synthesized thiazole, imidazole and tetrahydropyridine derivatives on e. coli .   methods : for evaluation of antibacterial eff...

background:  one of the most common infections in human is urinary tract infection  (uti)  and  uropathogenic   escherichia  coli   is  one  of  its  major causative agents . uti is extremely common among young women. children under age 5 are also highly at risk. considering the prevalence of this disease, it is necessary  to design  an appropriate  diagnostic  method  for its effective diagnos...
