Escherichia coli O104:H4 – enterohemolityczny szczep bakterii Escherichia coli odpowiedzialny za epidemiczne zachorowania, które rozpoczęły się na terenie Niemiec od połowy maja 2011. Wydziela on tzw. werotoksynę, która może uszkadzać naczynia włosowate, przede wszystkim w nerkach, płucach, mózgu i sercu. 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.

– Serotyp E coli O104:H4. • Sorbitol positiva E coli O157:H-. (Tyskland, rå korv mortadella  Infektion med verotoxinbildande Escherichia coli (VTEC) är en av infektion med VTEC (serotyp O104:H4) i norra Tyskland våren 2011. En qPCR analys utvecklades för detektion av Escherichia coli O157: H7 riktar en som undersöktes, inklusive de sex stora icke-O157 STEC stammar, O104: H4  en särskilt virulent E. coli stam av typen O104:H4.

As in the O157 E. coli prophage 933W, the Shiga toxin 2 subunit A and B genes in the O104:H4 prophages were inserted between the genes encoding the antitermination protein Q and the S/R lysis proteins of a lambdoid phage. The high degree of nucleotide sequence identity between the O157 and O104 prophages suggests a horizontal gene transfer event. 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.

2012-08-01 · Therapeutic concentrations of antibiotics inhibit Shiga toxin release from enterohemorrhagic E. coli O104:H4 from the 2011 German outbreak. Corogeanu D(1), Willmes R, Wolke M, Plum G, Utermöhlen O, Krönke M. Escherichia coli O104:H4 — высоко патогенный энтерогеморрагический штамм кишечной палочки, до 2011 An outbreak caused by Shiga-toxin–producing Escherichia coli O104:H4 occurred in Germany in May and June of 2011, with more than 3000 persons infected.

Outbreak of Shiga toxin-producing Escherichia coli O104:H4 associated with organic fenugreek sprouts, France, June 2011. As in the O157 E. coli prophage 933W, the Shiga toxin 2 subunit A and B genes in the O104:H4 prophages were inserted between the genes encoding the antitermination protein Q and the S/R lysis proteins of a lambdoid phage. The high degree of nucleotide sequence identity between the O157 and O104 prophages suggests a horizontal gene transfer event. 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).

O104:H4 outbreak resulted in thousands of cases of enterohaemorrhagic illness, with approxi-mately 25% of these progressing to develop haemolytic uraemic syndrome (HUS). This high rate of progression to HUS was the first indicator that the bacterial cause of illness was not a typical enterohaemorrhagic .

Methods.: The E. coli O104:H4 contains a toxin-encoding phage that is similar to 933W phage found in EHEC (2) but with one nucleotide change in each of the subunits (Stx2A and Stx2B) (4). The Germany outbreak strain contains another virulence factor referred to SPATEs (Serine Protease Autotransporter Toxins).

Aunque la mayoría de las cepas son inocuas y viven en los intestinos de los seres humanos y animales saludables, esta cepa produce una potente toxina y puede ocasionar enfermedades graves como el síndrome urémico hemolítico.

21, 22 The main virulence factor of STEC with a role in the pathogenesis of HUS is the production of at least one Shiga toxin type. 23 The identification of L'Escherichia coli O104: H4 è un ceppo enteroaggregativo del batterio Escherichia coli, esso è stato causa dell'epidemia di Escherichia coli O104: H4 del 2011. La "O" nella classificazione sierologica identifica l'antigene lipopolisaccaride della parete cellulare e la "H" identifica l'antigene flagello. Canadian press reported Monday afternoon that the deadly E. coli O104:H4 outbreak has now sickened more than 2,330 people across Europe, most of them in Germany, over the past month. The first case has also shown up in Canada in an Ontario man who travelled to Germany this spring.
