| enterotoxigenic escherichia coli isolated from patients at a hospital in dacca. | enterotoxigenic strains of escherichia coli, a significant cause of acute, watery, cholera-like diarrhea, were isolated from 23 of 65 patients with diarrhea in whom no other enteric pathogens were found during one week (november 1974) at the cholera research hospital, dacca, bangladesh. diarrhea associated with enterotoxigenic strains of e. coli occurred primarily in adults but affected persons of all age groups and could not be distinguished from cholera or from other cholera-like diarrhea on c ... | 1977 | 320276 |
| isolation of enterotoxigenic vibrio cholerae non-01 from the buriganga river and two ponds of dhaka, bangladesh. | vibrio cholerae 01 is usually considered the most toxigenic member of the vibrionaceae and v. cholerae non-01 isolated from the environment is non-toxigenic. in our survey of the pollution of some aquatic environments in and around dhaka, bangladesh, we wanted to investigate the toxigenicity of v. cholerae non-01 isolated from water and sediment samples of the buriganga river and two ponds in dhaka, in the rabbit ileal loop (ril) model. fluid accumulation was induced by 18 of 28 live cultures an ... | 1992 | 1296941 |
| electropherotyping of plasmid dna of different serotypes of shigella flexneri isolated in bangladesh. | one hundred and twenty-five shigella flexneri strains, isolated during january-december 1984, at the dhaka treatment centre of the international centre for diarrhoeal disease research, bangladesh, were serotyped using absorbed rabbit antisera specific for all type- and group-factor antigens, as well as a group of ten mouse and rat monoclonal antibodies. electropherotypes of the plasmid deoxyribonucleic acid (dna) were also determined. s. flexneri 2a was the predominant serotype followed by 3b, 1 ... | 1989 | 2661251 |
| enterotoxigenicity, hemolytic activity and antibiotic resistance of aeromonas spp. isolated from freshwater prawn marketed in dhaka, bangladesh. | aeromonas spp. were isolated from gills, swimmerets, eggs, stomachs and ventral muscles of freshwater prawns (macrobrachium malcolmsonii) available in the local fish market of dhaka, bangladesh. the density of aeromonas spp. on these different body parts of the prawn samples ranged from 1.1 +/- 0.2 x 10(4) to 1.5 +/- 0.16 x 10(7) cfu per gram. the viable counts of aeromonads, fecal coliforms (fc) and escherichia coli gradually increased in prawn samples when stored at 4 c. at -20 c, the viable c ... | 1994 | 7869955 |
| toxin(s), other than cholera toxin, produced by environmental non o1 non o139 vibrio cholerae. | a total of 39 vibrio cholerae non o1 non o139 strains were isolated from surface waters of different parts of dhaka city, bangladesh. all these strains showed lack of ctx or zot gene, as demonstrated by the pcr analysis. eighteen representative strains were tested for enterotoxin production using a rabbit ileal loop model, of which live cells of 8 strains and culture filtrates of 6 strains produced fluid accumulation in ileal loops. however, none of them produced heat stable toxin (st), as detec ... | 2006 | 16696898 |
