A lactose slow-fermenting, non motile Escherichia coli strain was isolated from a diarrheal patient returning from Indonesia. Examination of virulence of the strain showed that it penetrated into tissue culture cells, and were positive in Serény test and enzyme-linked immunosorbent assay for detection of enteroinvasive E. coli. A large plasmid responsible for virulence was also detected. Thus the strain was confirmed to be a typical enteroinvasive E. coli. Analysis of O serotype using the antisera against E. coli O1-O170 revealed that the strain had O121 antigen, whose antiserum is not included in the commercial serotyping kit for the diagnosis of diarrheagenic E. coli.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D003967 Diarrhea An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight. Diarrheas
D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
