In 2011, a large outbreak of infections caused by Shiga toxin-producing Escherichia coli (STEC) O104:H4 occurred in Germany. This exceptionally virulent strain 

The European Centre for Disease Prevention and Control (ECDC) reported Monday that the European toll in the outbreak of E. coli O104:H4 in Germany and France linked to sprouts had risen to 4,173 illnesses and 49 deaths.

The "O" in the serological classification identifies the cell wall lipopolysaccharide antigen, and the "H" identifies the flagella antigen. Escherichia coli O104:H4 is an infrequently isolated pathogenic E. coli serotype and the cause of the 2011 European diarrheal outbreak ( Mellmann et al., 2011 ).

Escherichia coli O104:H4 is an infrequently isolated pathogenic E. coli serotype and the cause of the 2011 European diarrheal outbreak ( Mellmann et al., 2011 ). Analysis of genome sequences obtained from several outbreak isolates showed that the E. coli O104:H4 strain is an enteroaggregative E. coli (EAEC; for further details, see Chapter 8) that Outbreaks of E. coli O104:H4 infection: update 28 (01-07-11) On 28 June 2011, the Institut de veille sanitaire, France, published new figures for the verocytotoxin-producing Escherichia coli (VTEC)/haemolytic uraemic syndrome (HUS) outbreak in the Bordeaux region in France, where in total 8 cases of bloody diarrhoea and 8 HUS cases have been reported since 22 June. E. coli O104:H4 infection A novel strain of Escherichia coli O104:H4 bacteria caused a serious outbreak of foodborne illness focused in northern Germany in May through June 2011. The illness was characterized by bloody diarrhea, with a high frequency of serious complications, including hemolytic-uremic syndrome, a condition that requires urgent treatment. The outbreak was originally thought to have been caused by an enterohemorrhagic strain of E. coli, but it was later shown to have been caused by an In May 2011, a large food-borne outbreak was traced to an unusual O104:H4 enteroaggregative Escherichia coli (EAEC) strain that produced Shiga toxin (Stx) type 2 (Stx2). We developed a mouse model to study the pathogenesis and treatment for this strain 5 July 2011. The EFSA Task Force established to coordinate investigations to track down the possible source of the French and German outbreaks of E. coli O104:H4 has concluded that one lot of fenugreek seeds imported from Egypt and used to produce sprouts is the most likely common link between the two outbreaks.

We developed a mouse model to study the pathogenesis and treatment for this strain and examined the virulence of the isolate for Dutch belted rabbits. Scientists of the National Reference Laboratory for Escherichia coli at the Federal Institute for Risk Assessment (BfR) have confirmed the results of the Land authorities in North Rhine-Westphalia: Raw sprouts contaminated with EHEC, which originated from the household of EHEC patients in North Rhine-Westphalia, were contaminated with the EHEC strain O104:H4. To the Editor: Beginning in early May 2011, an outbreak caused by Shiga toxin–producing Escherichia coli O104:H4 was reported in Germany and other countries in Europe. In this outbreak, the number of hemolytic uremic syndrome (HUS) cases has been unusually high ().As of June 9, 2011, a total of 722 cases of HUS, 19 deaths, and 2,745 cases of enterohemorrhagic E. coli (EHEC) infection were breaks-of-e.-coli-o104h4-infection-update-30, accessed by Sept 16, 2011).

Escherichia coli is a Gram-negative straight rod, which either uses peritrichous flagella for mobility or is nonmotile. It is a facultatively anaerobic chemoorganotroph capable …

The cases recorded in Germany were 3078 EHEC and 857 HUS cases, with 48 dead; in other countries, there were 89 EHEC and 51 HUS cases. The Robert Koch Institute (RKI), the university medical center Hamburg- Eppendorf, and the health department of the Hamburg AP reports a few moments ago that local German organic vegetable sprouts have been linked epidemiologically to the E. coli O104:H4 outbreak that has killed 30 people and sickened nearly 3,000 – nearly 750 with Hemolytic Uremic Syndrome. A key event in the evolution of fully virulent E. coli O104H4 capable of causing HUS was acquisition of O104H4-G (the stx 2-containing prophage). This group of prophages exhibits relatively minimal variation (see Fig. S3G in the supplemental material), consistent with the idea that lysogenization of the ancestor of clades 1 and 2 with a Shiga toxin-encoding phage occurred relatively recently. Escherichia coli is a Gram-negative straight rod, which either uses peritrichous flagella for mobility or is nonmotile. It is a facultatively anaerobic chemoorganotroph capable of both respiratory and fermentative metabolism.

Reminders of this chastening fact include the devastating outbreak of Escherichia coli O104:H4 in Germany in 2011, in which 54 people died and 22% of the 3186 cases of E. coli O104 developed the severe complication, hemolytic uremic syndrome (HUS). A major outbreak caused by Escherichia coli of serotype O104:H4 spread throughout Europe in 2011. This large outbreak was caused by an unusual strain that is most similar to enteroaggregative E The outbreak of E. coli O104:H4 resulted in a large number of cases of bloody diarrhoea and haemolytic uraemic syndrome (HUS) in Germany, and in 15 other countries in Europe and North America. The O104H4. It is used to detect the somatic antigen O and flagellar antigen H as compared with other methods of diagnosis; results indicated that 97% of isolates were E. coli.The . E. coli Based on the strain analysis of the serotype O104:H4, BfR believes that it is likely that the transfer of the pathogen to the affected foods could have been caused in the current outbreak event via humans or from humans via the environment. The pathogen can be spread through foods.

Isolates of Escherichia coli O104:H4 from the outbreak centered in Germany in May-July 2011, and the much smaller outbreak in southwest France in June 2011, were indistinguishable by standard tests (O104H4-A, -B, -D, -E, -F, and -G) were likely acquired prior to the divergence of clade 1 and 2 lineages (with subsequent loss of phage O104H4-D from Ec09-7901).
