We additionally placed the outbreak isolates into broader phylogenetic context using C227-11 as representative of the outbreak: historical E. coli O104:H4 isolates 55989 [isolated from an HIV-positive adult from the Central African Republic in the 1990s that, like the other isolates, is enteroaggregative, but, in contrast, is not Shiga toxin-producing ], 01–09591 [isolated from an individual The highly virulent E. coli O104:H4 outbreak strain LB226692 possesses a blended virulence profile combining genetic patterns of human adapted enteroaggregative E. coli (EAEC), rarely detected in animal hosts before, and enterohemorrhagic E. coli (EHEC), a subpopulation of Shiga toxin (Stx)-producing E. coli (STEC) basically adapted to the ruminant host. Escherichia coli O104:H4 is een gram-negatieve bacterie. Het is een zeer zeldzame enterohemorragische E. coli-stam (EHEC) . Deze variant lijkt naast een vastgestelde resistentie voor een aantal antibiotica ook een negatievere prognose te kennen dan de meer courante EHEC-stammen.

Escherichia coli O104:H4 (strain 2011C-3493) was isolated from human stool from a US patient with a history of travel to Germany in May 2011 during a large outbreak of bloody diarrhea with a high prevalence of hemolytic uremic syndrome cases; it is Shiga toxin (stx2) positive. The outbreak was caused by a new pathotype of EHEC O104:H4 (041). The 2011 E. coli O104:H4 outbreak of hemorrhagic diarrhea in Germany is an example of the explosive cocktail of high virulence and resistance that can emerge in this species. A total of 46 deaths, The Germany outbreak strain was identified as serotype O104:H4 and contained virulence features that were seen in enteroaggregative E. coli (EAEC) and enterohemorraghic E. coli (EHEC).

In May 2011, a virtually unknown strain of E. coli, known as O104:H4, made worldwide headlines when an outbreak in Germany sickened approximately 4,000 people and killed 50, including one American. a STEC serotype called O104:H4, and fenugreek sprouts were identified as the most likely origin (1). O104:H4 had not before been associated with severe infections (2). The outbreak was in fact not caused by a STEC strain but by another type of pathogenic .

E. coli O104:H4 There are more than 700 infectious serotypes (closely related though distinguishable forms) of E. coli. The serotypes are classified based on the antigens (proteins that stimulate antibody production in animals) on their surfaces, with the O (cell wall) and H (flagellar) antigens being of primary importance. Outbreaks of E. coli O104:H4 infection: update 30 (22-07-11) The number of new cases of Escherichia coli O104:H4 infection in Germany and France is much diminished. The figures reflect some delayed reporting, and the evidence indicates that the outbreak, which took 50 lives in Germany alone, is nearly over.

Here, we summarize some pertinent features of the German O104:H4 epidemic and the possibilities for treatment and prevention. On 21 May 2011, Germany reported an ongoing outbreak of Shiga-toxin producing Escherichia coli (STEC), serotype O104:H4. From an initial case control study, the outbreak was associated with the consumption of fresh salad vegetables. Subsequent investigations showed that the risk of infection was significantly associated with the consumption of fresh sprouted seeds rather than with other fresh Escherichia coli EHEC O104:H4 ist ein seltener Hybrid-Stamm des Bakteriums Escherichia coli aus dem enteroaggregativen Escherichia coli EAEC O104:H4 sowie einem EHEC-Stamm.
