We characterized two STEC O104 : H4 clinical isolates collected in Poland from a 7-year-old boy with haemolytic uraemic syndrome (HUS) and his nanny. This household outbreak began on 29 May 2011. Because of its time-frame, the outbreak was assumed to be part of the international STEC O104 : H4 outbreak that arose in Germany in May 2011. The two Polish isolates were Shiga-toxin-producing Escheri...

Shiga toxin-producing Escherichia coli (STEC) is an important foodborne pathogen. Here, we report complete whole-genome sequences for two STEC strains of serotypes O119:H4 and O165:H25 isolated from clinical cases in the United States.

BACKGROUND AND OBJECTIVES Infectious diarrhoeal diseases are great problem throughout the world and are responsible for considerable morbidity and mortality. Shiga toxin-producing Escherichia coli (STEC) is a major cause of gastroenteritis that may be complicated by hemorrhagic colitis (HC) or the hemolytic uremic syndrome (HUS), which is the main cause of acute renal failure in children. Food-...

The objective of this review is to highlight the importance of cattle in human disease due to Shiga toxin-producing Escherichia coli (STEC) and to discuss features of STEC that are important in human disease. Healthy dairy and beef cattle are a major reservoir of a diverse group of STEC that infects humans through contamination of food and water, as well as through direct contact. Infection of ...

The plasmid-borne sfpA gene encodes the pilin subunit in sorbitol-fermenting (SF) enterohemorrhagic Escherichia coli (EHEC) O157:H-. We investigated the distribution of sfpA among 600 E. coli isolates comprising the complete E. coli standard reference (ECOR) and diarrheagenic E. coli (DEC) strain collections and clinical isolates associated with enteric disease. sfpA was detected in DEC3F SF EH...

AIMS To study the occurrence and spatial distribution of Shiga toxin-producing Escherichia coli (STEC) O157 in calves less than 1-week-old (bobby calves) born on dairy farms in the North Island of New Zealand, and to determine the association of concentration of IgG in serum, carcass weight, gender and breed with occurrence of E. coli O157 in these calves. METHODS In total, 309 recto-anal muc...

Shiga toxin-producing Escherichia coli (STEC) strains belong to the group of pathogens that cause bloody diarrhea and hemorrhagic colitis with often severe complications. The main problem with human pathogenic E. coli strains, including STEC, is a wide spectrum of phenotypes and clinical manifestations. It is related to a variety of exchangeable genetic elements, like plasmids, bacteriophages,...

Toxin-producing Escherichia coli expressing F18 fimbriae colonizes the small intestines of weaned pigs and causes diarrhea, edema disease, or both. The F18 family is composed of two antigenic variants, F18ab and F18ac. Because many strains do not express F18 fimbriae in vitro, identification and differentiation of these two variants are difficult. Single-strand conformational polymorphism (SSCP...

Shiga toxin-producing E. coli O157:H7 and non-O157 have been implicated in many foodborne illnesses caused by the consumption of contaminated fresh produce. However, data on their persistence in soils are limited due to the complexity in datasets generated from different environmental variables and bacterial taxa. There is a continuing need to distinguish the various environmental variables and...
