The highly virulent Escherichia coli O104:H4 that caused the large 2011 outbreak of diarrhoea and haemolytic uraemic syndrome secretes blended virulence factors of enterohaemorrhagic and enteroaggregative E. coli, but their secretion pathways are unknown. We demonstrate that the outbreak strain releases a cocktail of virulence factors via outer membrane vesicles (OMVs) shed during growth. The O...
Abstract Background The diagnostics of travellers’ diarrhoea (TD) has been revolutionised by multiplex qPCR assays. While mostly bacterial aetiology, viruses and parasites account for the disease among 10–20% travellers. Despite this, prospective studies applying assays remain scarce that cover not only bacteria, such as various diarrhoeagenic Escherichia coli (DEC), but also viral parasitic pa...
Enterohaemorrhagic Escherichia coli (EHEC) is a group of pathogenic Shiga toxin-producing E. coli that can cause haemorrhagic colitis and haemolytic uraemic syndrome (HUS). The disease usually occurs sporadically, but sometimes also occurs in large outbreaks such as that which recently occurred in northern Germany. EHEC infection is a zoonosis and its reservoir is in ruminant farm animals (catt...
We identified different diarrheagenic (DEC) Escherichia coli pathotypes isolated from 1,207 children with and without acute endemic diarrhea in Salvador, Bahia, Brazil collected as part of a case-control study. Since the identification of DEC cannot be based on only biochemical and culture criteria, we used a multiplex polymerase chain reaction developed by combining five specific primer pairs ...
A total of 90 random samples of ready to-eat-pastry foods of meat pie, meat pizza and pasta pashamil. 30 samples of each were collected from different fast foods services at Kalyobia governorate to be examined bacteriologically for detection of pathogenic Escherichia coli microorganisms. The obtained results indicate that incidence of E.coli isolated from examined samples of pastry foods were 2...
