“…DISCUSSION VTEC were not isolated in patients with IBD included in this study in contrast to the previously reported evidence suggesting that these organisms may have an aetiological role [9]. The failure to detect VTEC in other patient groups supports published data that they cause under 2 % of gastroenteritis in the UK [14]. It is possible that some cases could have been missed, as the rate of detection of VTEC in stools falls dramatically after the first few days of infection [15], and the VT property in E. coli 0 2.…”

SUMMARYOne hundred and eighty-one stool specimens from patients with various types of diarrhoea (135 patients) or from non-diarrhoeal controls (23 acute medical patients, 23 inflammatory bowel disease in remission) were investigated using a colony-blot DNA hybridization assay for the presence of Verocytotoxin-producing (VTEC), enteroaggregative (EAggEC) and diffusely adherent (DAEC) Escherichia coli. Twelve patients had probe-positive EAggEC in the stool and 8 of these had diarrhoea, 6 following recent travel. Eight patients had DAEC, 7 of whom had travellers' diarrhoea. Six of 10 (60%) travellers with gastroenteritis, but without a recognized enteric pathogen, were positive for EAggEC (4) or DAEC (2). Five of 10 (50%) travellers with gastroenteritis related to a recognized enteric pathogen also had DAEC identified in their stool. Of the 23 acute medical control patients 11 had been abroad, 4 of these were immigrants and had EAggEC. VTEC were not found and, with one exception, immunoassays for antibodies to E. coli 0 157 and O 2 lipopolysaccharides were negative.

“…The incidence of VTEC infections has not yet been extensively studied in Europe. Only in the UK has the role of VTEC been evaluated in hemorrhagic colitis (4), hemolytic uremic syndrome (5) and diarrhea (6). Outbreaks of hemorrhagic colitis and hemolytic uremic syndrome have also been reported in the UK (7,8).…”

During an 18-month period all stools submitted to a microbiology laboratory in Belgium for culture were screened for Verocytotoxin-producing Escherichia coli (VTEC) serotype O157. In the stool samples from 3940 patients, eight (0.2%) VTEC O157 strains were isolated, seven of which were O157:H7. Additional screening for other serotypes of VTEC in 332 selected stool samples yielded four more strains (serotypes O2:K1:H6, O111:H-, O117:K1:H7 and O"C70/86":H-). The 0.3% isolation rate for all VTEC was comparable to that for Shigella spp. Eight children under 30 months and two adults suffered from uncomplicated gastroenteritis. A 5-month-old child and a 41-year-old woman presented with hemolytic uremic syndrome a few days after onset of a diarrheal episode.

“…Both types of shiga-toxic factors, Shiga-like toxin I and Shiga-like toxin II, killing both Vero and HeLa cells, induce fluid accumulation in ligated rabbit intestinal loops, and are lethal for mice and rabbits (5,6,7,8,9,10). Both toxic factors differ antigenically as well as with respect to their biological effect.…”

, a total of 1094 faecal swab samples were collected from cattle at different age at 4 farms in North Bulgaria: Okorsh, Slavyanovo (Popovo municipality), Dobri dol and Trem. Out of them, 36 coli strains (3.3%) positive in the E. coli O:157 antiserum agglutination test and identified by the BBL CRYSTAL identification system as belonging to the E. coli O:157 serotype were isolated. The distribution of isolates was as followed: 5 (0.5%) E. coli O:157 strains at the Okorsh dairy cattle farm, 7 (0.6%) E. coli isolates at the Slavyanovo dairy farm, 16 (1.5%) isolates at the Dobri dol farm and 8 (0.7%) isolates at the Trem farm. Colibacteria exhibited 100% sensitivity to oxyimino-cephalosporins, gentamicin and enrofloxacin, and were resistant to ampicillin (19.4%) and tetracycline (41.6%). From the 15 strains resistant to tetracycline, 11 were isolated from the cows at Dobri dol, while the other 4 originated from the other three farms. The 7 ampicillin-resistant E. coli isolates were detected only at the Dobri dol cattle farm.
