phylogenetic relationships among clonal groups of extraintestinal pathogenic escherichia coli as assessed by multi-locus sequence analysis.the evolutionary origins of extraintestinal pathogenic escherichia coli (expec) remain uncertain despite these organisms' relevance to human disease. a valid understanding of expec phylogeny is needed as a framework against which the observed distribution of virulence factors and clinical associations can be analyzed. accordingly, phylogenetic relationships were defined by multi-locus sequence analysis among 44 representatives of selected expec clonal groups and the e. coli reference (ecor) coll ...200616820314
isolation of escherichia fergusonii from the feces and internal organs of a goat with diarrhea.a fecal sample from a 42-year-old goat with a 2-month history of poor weight gain and diarrhea yielded a moderate growth of an organism resembling salmonella spp. on macconkey agar. the organism was identified as escherichia fergusonii. the animal was euthanized. samples of intestine, lung, liver, and kidney yielded the same organism, e. fergusonii.200717616063
multidrug-resistant escherichia fergusonii: a case of acute cystitis.we report a case in which escherichia fergusonii, an emerging pathogen in various types of infections, was associated with cystitis in a 52-year-old woman. the offending strain was found to be multidrug resistant. despite in vitro activity, beta-lactam treatment failed because of a lack of patient compliance with therapy. the work confirms the pathogenic potential of e. fergusonii.200818256229
characterisation of escherichia fergusonii isolates from farm animals using an escherichia coli virulence gene array and tissue culture adherence assays.escherichia fergusonii has been associated with a wide variety of intestinal and extra-intestinal infections in both humans and animals but, despite strong circumstantial evidence, the degree to which the organism is responsible for the pathologies identified remains uncertain. thirty isolates of e. fergusonii collected between 2003 and 2004 were screened using an escherichia coli virulence gene array to test for the presence of homologous virulence genes in e. fergusonii. the iss (increased ser ...200918585745
