Isolation of verotoxin-producing Escherichia coli O-rough:K1:H7 from two patients with traveler's diarrhea.
Two Escherichia coli O-rough:K1:H7 strains producing verotoxin 1 that were isolated from stool samples of two travelers with diarrhea who consulted our clinic after trips to the Indian Subcontinent and Central America were characterized. Both strains were sorbitol negative, the same phenotype presented by E. coli O157:H7, but in contrast they were beta-glucuronidase positive. Low-frequency rest...
متن کاملIsolation of Escherichia coli bacteriophages from the stool of pediatric diarrhea patients in Bangladesh.
A 3-week coliphage survey was conducted in stool samples from 140 Bangladeshi children hospitalized with severe diarrhea. On the Escherichia coli indicator strain K803, all but one phage isolate had 170-kb genomes and the morphology of T4 phage. In spot tests, the individual T4-like phages infected up to 27 out of 40 diarrhea-associated E. coli, representing 22 O serotypes and various virulence...
متن کاملCHA RA CTERIZATION OF VEROTOXIN-PRODUCING STRA INS OF ENTEROPATHOGENIC ESCHERICHIA COLI (EPEC) FROM CHILDREN WITH DIA RRHOEA: EFFECTS OF THE TOXIN ON RABB IT INTESTINE
249 enteropathogenic Escherichia coli (EPEC) strains from faecal samples of 90 children with diarrhoea were examined for verotoxin (VT) production. Polymyxin B extracts of 61 strains belonging to 9 serogroups from 35 children produced various verotoxins (VTs). The titre of these various VTs ranged from I :40 to I: 12HO. Of the 26 (43.6%) adherent strains, 19 (73%) exhibited localized adhere...
متن کاملSubtilase cytotoxin-coding genes in verotoxin-producing Escherichia coli strains from sheep and goats differ from those from cattle.
Subtilase cytotoxin (SubAB) from verotoxin (VT)-producing Escherichia coli (VTEC) strains was first described in the 98NK2 strain and has been associated with human disease. However, SubAB has recently been found in two VT-negative E. coli strains (ED 591 and ED 32). SubAB is encoded by two closely linked, cotranscribed genes (subA and subB). In this study, we investigated the presence of subAB...
متن کاملDoes levofloxacin induce hemolytic uremic syndrome in patients infected with verotoxin-producing Escherichia coli O157 infections?
Fifteen Japanese colitis patients, aged above 16 years old, infected with verotoxin-producing Escherichia coli O157 (VTEC O157) were divided into 2 treatment groups. Of the 15 patients, 6 (mean ± SD, 41.3 ± 19.0 years old) were treated with levofloxacin (LVFX), while the remaining 9 patients (32.0 ± 10.0 years old) were not treated with any antimicrobial agents. All patients complained of ab...
