The "O" in the serological classification identifies the cell wall lipopolysaccharide antigen, and the "H" identifies the flagella antigen.

O104h4 e coli

Escherichia coli O104:H4 is an enteroaggregative Escherichia coli strain of the bacterium Escherichia coli, and the cause of the 2011 Escherichia coli O104:H4 outbreak. The "O" in the serological classification identifies the cell wall lipopolysaccharide antigen, and the "H" identifies the flagella antigen. Analysis of genomic sequences obtained by BGI Shenzhen shows that the O104:H4 outbreak strain is an enteroaggregative E. coli type that has acquired Shiga toxin genes, presumably by horizonta 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 has acquired the Shiga toxin genes, presumably by bacteriophage transduction ( Brzuszkiewicz et al., 2011; Mellmann et al., 2011; Rasko et al., 2011; Outbreak Summary. CDC is monitoring a large outbreak of Shiga toxin-producing Escherichia coli O104:H4 (STEC O104:H4) infections ongoing in Germany. The responsible strain shares virulence characteristics with enteroaggregative E. coli (EAEC). As of July 5, 2011, case counts confirmed by Germany’s Robert Koch Institute include 852 patients with hemolytic uremic syndrome (HUS)–a type of kidney failure that is associated with Shiga toxin-producing E. coli, or STEC, infections–and 32 HUS The causative EAEC O104:H4 bacterium of the 2011 outbreak was initially described as a strain of EHEC, but subsequent genetic analyses revealed that it was closely related to EAEC; some scientists classified it as a new pathotype, enteroaggregative-hemorrhagic E. coli (EAHEC), though this was not widely accepted.

Most STEC infections are caused by E.coli organisms in the O157 serogroup, causing more than 800 cases of illness in England and Wales every year and primarily affecting the young (0-5 years) and the old (75+ years). In 2009, an outbreak of E.coli O157 in Surrey resulted in in 17 children being hospitalised with HUS.

In last year’s outbreak of E. coli O104:H4, which began in Germany and was linked to sprouts grown from contaminated fenugreek seeds, there were at least 50 fatalities among the 4,000 sickened.

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).
