Bacterial co-infections can probably influence the pathogenicity of H9N2 low pathogenic avian influenza virus (AIV). This study aimed to evaluate the effect of exposure time to Escherichia coli (O:2) on the pathogenicity of H9N2 AIV in broiler chickens. Three hundred and sixty broiler chickens were randomly allocated to six equal groups. At the age of 26 days, all chicks except groups 5 and 6 w...

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...

Background & Objective: Escherichia coli (E. coli) is considered to be the most common cause of urinary tract infections (UTIs) worldwide. Due to the recent rise in bacterial resistance to antibiotics and the appearance of multidrug-resistant E. coli, treatment options have been significantly limited, thus increasing the cost of treatment as well as morbidity and mortality rates, especially in ...

background and objectives: a diverse group of escherichia coli are known as enterohemorrhagic escherichia coli (ehec) including o157:h7 and non-o157 ehec. enterohemorrhagic strains are related to severe clinical conditions in humans including hemorrhagic colitis and hemolytic uremic syndrome, and most of the recorded outbreaks occurred due to o157: h7 e. coli . the aim of the present study was ...

background and objectives: pathogenic strains of escherichia coli are a common cause of acute infectious diarrhea. the aim of this study was to investigate the frequency, virulence markers and antibiotic resistance patterns of diarrheagenic e. coli (dec) isolated from adolescents and adults in hamadan, west of iran. materials and methods: a total of 187 stool samples were collected from adults ...

background: enterohemorrhagic escherichia coli (ehec) o157:h7 is an infectious zoonotic pathogen causing human infections. these infections, in some cases, can lead to hemolytic uremic syndrome and its life-threatening complications and even death worldwide. the first intimate bacterial adhesion, intimin (i), with its own receptor translocated intimin receptor (tir) and e. coli secreted protein...

pigeons can be carriers of some human pathogens and contribute to transmission and spread of drug resistant infectious agents to human. considering many people’s interests to keep pigeons, present study was conducted to pcr detection of escherichia coli o157:h7 that is responsible for outbreaks of human intestinal diseases and fatal haemolytic-uraemic syndrome worldwide and evaluation of resist...
