Background and Aim: The pathogenicity of Escherichia coli is determined by the presence genes that mediate virulence factors such as adherence capacity toxin production. This research aimed to identify adhesion antibiotic resistance E. strains associated with diarrhea in piglets Colombia. Materials Methods: Presumptive were isolated from rectal swabs swine farms between 4 40 days age evidence d...

مقدمه: برخی از سویه های پاتوژنیک اشرشیاکلی می توانند باعث انواعی از بیماری های رود ه ای و خارج روده ای شوند. از مسایل مهم در درمان بیماری های عفونی، مقاومت باکتری های پاتوژن نسبت به آنتی بیوتیک ها می باشد. هدف از این مطالعه، بررسی میزان فراوانی ژن های پاتوتیپ های eaec (enteroaggregative escherichia coli)، epec (enteropathogenic escherichia coli) و مقاومت آنتی بیوتیکی اشرشیاکلی جدا شده از عفونت ...

In the present study, 470 children less than 72 months of age and presenting acute diarrhea were examined to identify associated enteropathogenic agents. Viruses were the pathogens most frequently found in stools of infants with diarrhea, including 111 cases of rotavirus (23.6% of the total diarrhea cases) and 30 cases of adenovirus (6.3%). The second group was diarrheogenic Escherichia coli (8...

Diarrheagenic Escherichia coli (DEC) is important bacteria of children's endemic and epidemic diarrhea worldwide. The aim of this study was to determine the prevalence of DEC isolated from stool samples collected from children with acute diarrhea living in Ouagadougou, Burkina Faso. From August 2013 to October 2015, stool samples were collected from 315 children under 5 years of age suffering f...

The purpose of this study was to investigate extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli isolates from pediatric (aged 0 to 3 years) diarrhea patients in Surabaya, Indonesia, where this kind of survey is rare; our study included assessment of their antibiotic susceptibilities, as well as ESBL typing, multilocus sequence typing (MLST), and diarrheagenic E. coli (DEC)-typin...

Escherichia coli is a normal inhabitant of the gastrointestinal tract of all warm-blooded animals, but variants of this species is also among the important etiological agents of enteritis and several extraintestinal diseases. The E. coli strains that cause diarrhoeal illness are categorised into pathogenicity groups based on virulence properties, mechanisms of pathogenicity, clinical symptoms a...

We previously suggested that the ability to metabolize deoxyribose, a phenotype encoded by the deoK operon, is associated with the pathogenic potential of Escherichia coli strains. Carbohydrate metabolism is thought to provide the nutritional support required for E. coli to colonize the intestine. We therefore investigated the role of deoxyribose catabolism in the colonization of the gut, which...

the main features of enteroaggregative escherichia coli (eaec) pathogenesis include attachment of bacteria to the intestinal mucosa, production of various toxins and cytotoxins, and stimulation of mucosal inflammation. ‘virulence’ genes encode these features. comparison of different eaec isolates has shown that the virulence gene content of these isolates varies considerably. the heterogeneity ...

To document the association of pathogenic Escherichia coli with diarrhea in Romanian children, 250 E. coli fecal isolates from children under 5 years of age were PCR-screened for well-recognized virulence determinants, as well as for their phylogenetic background. The putative diarrheagenic E. coli (DEC) were investigated for susceptibility to various antibiotics. Overall, 61 E. coli isolates w...

Pathogenic Escherichia coli can be released with the wastes coming from slaughterhouses into the environment, where they can persist. We investigated the presence of diarrheagenic E. coli in specimens taken at an abattoir located in the Zaria region, Nigeria, in samples of water from the river Koreye, where the effluent from the abattoir spills in, and vegetable specimens taken at a nearby farm...
