enteropathogenic escherichia coli diarrhea in hospitalized children in bangladesh.the role of enteropathogenic escherichia coli (epec) was evaluated in a group of children with endemic diarrhea admitted to dhaka shishu hospital in dacca, bangladesh. epec was detected in fecal samples of 23% of 104 cases and 8% of 74 concurrent control children. the most commonly isolated epec strains were serogroups o20a, o20c:k61; o20a, o20b:k84; o26:k60; and o18a, o18c:k77. except for o26:k60, these groups had not been reported from bangladesh. on testing for enterotoxin production, only tw ...19853902881
a novel serovar of shigella dysenteriae from patients with diarrhoea in bangladesh.every year, around 3 % of isolates from patients with diarrhoea at dhaka hospital, icddr,b, are identified as shigella-like organisms (slos) based on their activity in biochemical tests. these isolates do not react with any of the current shigella antisera including all existing and provisional serotypes. among these slos, a unique cluster of seven isolates with an identical plasmid profile was found and these isolates were further characterized by phenotypic and genotypic techniques. all were n ...200717446289
phenotypic and genotypic characterization of serologically atypical strains of shigella flexneri type 4 isolated in dhaka, bangladesh.twenty-one atypical shigella flexneri type 4 strains isolated from patients attending the dhaka treatment center of the international centre for diarrhoeal disease research, bangladesh, were extensively characterized and compared with s. flexneri serotypes 4a and 4b. the atypical strains agglutinated only with the type antigen factor 4 and did not agglutinate with any group factors, thereby excluding their characterization into serotype 4a or 4b. of the 21 strains, 85.7% did not ferment mannitol ...200212089268
