BACKGROUND Childhood diarrheal diseases remain highly endemic in developing areas of Brazil. The importance of Escherichia coli among children with diarrhea in these areas was unknown. This study determined the prevalence of different E. coli categories in symptomatic and asymptomatic children from low socioeconomic level rural communities in southeastern Brazil. METHODS A total of 560 stool ...

Background: Diarrheagenic Escherichia coli (DEC) is regarded as a great public health concern all around the world causing diarrhoea which can be transmitted through food chain. Aims: This study aimed to determine the contamination level and exact distribution rate of DEC in food products consumed by human. Methods: Seven hundred and t...

the present study was conducted to investigate antimicrobial resistant pattern of escherichia coli (e. coli) strains isolated from clinical specimens of jordanian pediatric patients during the period from january to december 2008. a total of 444 e. coli strains were isolated from clinical specimens and tested for their susceptibility to different antimicrobial drugs. overall, high resistance ra...

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...

Background: Various strains of Escherichia coli (E. coli) are known as major causes of intestinal and extraintestinal infections in humans and various animal species. Molecular methods are important for the identification of bacterial isolates and nucleotide sequence variations, as well as information on tracking bacterial agents related to the outbreaks, the frequency of the bacterial genetic ...

escherichia coli (e. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. phylogenetic analysis has shown that e. coli is composed of four main phylogenetic groups (a, b1, b2 and d). group a and b1 are generally associated with commensals, whereas group b2 is associated with extra-intestinal pathotypes. most enteropathogenic isolates, however, are assigne...

infectious diseases are responsible for thousands of worldwide early death .many commercial antibiotics have been used to control human's infectious diseases all over the world. calotropis procera linn a wild growing plant of asclepiadaecae family is known to possess multifarious medicinal properties. total 80 non repetitive clinical e. coli strains recovered during 7 month, and were screened f...

background uropathogenic escherichia coli (upec) is a causative agent of most of urinary tract infections (utis), which expresses a multitude of virulence factors. objectives the aim of this study was to investigate virulence associated characteristics characteristics in upec isolates derived from urine specimens, and to investigate the distribution of the pathogenicity islands virulence marker...

background : enteroaggregative e. coli (eaec) is increasingly recognized as a cause of often persistent diarrhea in children and adults in both developing and developed countries. the aim of the present study was to investigate the presence and the frequency of eaec as etiologic agent of diarrhea in shiraz. methods : a total of 715 stool samples were collected from patients with diarrhea in shi...
