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 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 When researchers committed to first mapping E. coli genomes back at the turn of the millennium, the sequencing process was a considerable technological undertaking, requiring millions of dollars REVIEW Open Access O157:H7 and O104:H4 Vero/Shiga toxin-producing Escherichia coli outbreaks: respective role of cattle and humans Denis Piérard1, Henri De Greve2,3, Freddy Haesebrouck4 and Jacques Mainil5* Culture Collections - consists of four UK Culture Collections including: European Collection of Cell Cultures (ECACC), National Collection of Type Cultures (NCTC), National Collection of Pathogenic Viruses (NCPV) and the National Collection of Pathogenic Fungi (NCPF). There is an outbreak of Escherichia coli O104:H4 infection in France, south of Bordeaux, where 8 cases of haemolytic uraemic syndrome (HUS) and 8 cases of bloody diarrhoea have been reported. This rare infection is caused by the same serotype, and probably the same strain, as seen in the recent and severe outbreak in Germany, which started in May. This document is an update of the EFSA/ECDC joint rapid risk assessment of 29 June and aims to add new information to this and earlier initial rapid risk assessments (27 May and 14 June 2011).

For anyone who hasn't been paying close attention to what's happening across the pond Jan 23, 2013. Study: Relatives of novel coronavrius common in bats Coronaviruses related to the novel corornavirus that infected nine people in the Middle East last year are fairly common in African and European bats, a finding that strengthens the evidence that the new virus originated in bats, according to a report published yesterday in Emerging Infectious Diseases. With every foodborne outbreak, there are always lessons to be learnt. Dr Lucia Anelich of Anelich Consulting, one of SA’s foremost micriobology and food safety authorities, writes that this devastating outbreak – 49 fatalities and 4 178 people sickened – underscores a number of issues, and at the same time, gives us cause to pause and to reflect upon our own systems in South Africa, both Rapid Screening Method for Multiple Gastroenteric We analyzed travel-associated clinical isolates of Escherichia coli O104:H4, including 1 from the 2011 German outbreak and 1 from a patient who returned from the Philippines in 2010, by genome sequencing and optical mapping. Despite extensive genomic similarity between these strains, key differences included the distribution of toxin and antimicrobial drug–resistance determinants. 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 (HUS), a condition that requires urgent treatment.

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 …

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 Methods. The objective of this review was the characterization of 2011 Shiga toxin-producing Escherichia coli (STEC) O104:H4 outbreak and its management.

The illness was characterized by bloody diarrhea, with a high frequency of serious complications, including hemolytic-uremic syndrome (HUS), a condition that requires urgent treatment. On July 27, a team led by researchers at the University of Maryland School of Medicine Institute for Genome Sciences published a paper in the New England Journal of Medicine on the completed genome 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. This document is an update of the EFSA/ECDC joint rapid risk assessment of 29 June and aims to add new information to this and earlier initial rapid risk assessments (27 May and 14 June 2011). The O104:H4 Shiga-toxic Escherichia coli (STEC) strain, designated NCTC 13562, responsible for the largest recorded STEC outbreak of haemolytic uraemic syndrome and bloody diarrhoea is available from PHE’s National Collection of Type Cultures (NCTC).

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. The degree to which molecular epidemiology reveals information about the sources and transmission patterns of an outbreak depends on the resolution of the technology used and the samples studied. 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).

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… 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 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. 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 (HUS), a condition that requires urgent treatment. 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. The E. coli O104:H4 Test is a rapid latex agglutination test, designed solely for the presumptive identification of Escherichia coli serogroup O104 cultured on TSA agar plate.
