National reporting of Shiga-like toxin (verotoxin) producing Escherichia coli infections and associated syndromes.
Infection with Shiga-like toxin (verotoxin) producing strains of Escherichia coli (SLTEC or VTEC) has the potential to cause severe and life threatening illness, including haemorrhagic colitis (HC), haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopaenic purpura (TTP). Such strains are found in some animals, and are transmitted to humans through ingestion of undercooked meat (especia...
متن کاملIsolation 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 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...
متن کاملFactors associated with fecal shedding of verotoxin-producing Escherichia coli O157 on dairy farms.
Fecal samples were collected from 4,361 dairy cows on 91 dairy operations between 26 February and 8 July 1996. Fecal samples were cultured for Escherichia coli O157, and positive isolates were probed for verotoxin-producing genes. A total of 52 (1.2%) fecal samples on 22 (24.2%) operations were positive for verotoxin-producing E. coli O157. Herds in which samples were collected on or after 1 Ma...
متن کاملLoss of O157 O antigenicity of verotoxin-producing Escherichia coli O157:H7 surviving under starvation conditions.
Verotoxin (VT)-producing Escherichia coli O157:H7 was culturable on agar media after being left in water for 21 months. However, there were a number of colonies which had lost O157 O antigenicity. These colonies produced VTs, which are pathogenic to humans. These observations suggest that the immunologic methods based on O157 O antigenicity are unable to detect and isolate VT-producing E. coli ...
