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). STEC O104:H4 was isolated at state public health laboratories or at CDC from Shiga toxin–positive stool enrichment broths submitted by clinical laboratories. 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. Other articles where EAEC O104:H4 is discussed: German E. coli outbreak of 2011: 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… 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).
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).

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).

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 … 19 rows 2013-09-09 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 … 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.
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

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.

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. The epidemic originated from a bean and seed sprouts farm in Lower Saxony, and was caused by the O104:H4 strain – a highly antibiotic resistant, hybrid enteroaggregative – Shiga toxin producing E. coli strain (STEC).
