A matched case-control study was conducted to study risk factors for domestically acquired sporadic Campylobacter infections in Finland. Swimming in natural sources of water was a novel risk factor. Eating under-cooked meat and drinking dug-well water were also independent risk factors for Campylobacter infection. C ampylobacter jejuni and C. coli are(More)

BACKGROUND Streptococcus equi subspecies zooepidemicus is a rare infection in humans associated with contact with horses or consumption of unpasteurized milk products. On October 23, 2003, the National Public Health Institute was alerted that within one week three persons had been admitted to Tampere University Central Hospital (TaYS) because of S. equi(More)
The ISEcp1 insertion sequence has been described as a fl anking region of several bla CTX-M genes and has been implicated in the expression and mobilization of the genes (5). A recent study by Lartigue et al. showed that a CTX-M-2 progenitor in K. ascorbata could be mobilized and transferred to a conjugative E. coli plasmid by the ISEcp1B element; enhanced(More)
We describe the outbreak investigation associated with an unusual increase in Salmonella Goldcoast cases in Hungary observed in autumn 2009, which included descriptive and analytical epidemiological studies and microbiological and veterinary investigations. Sixty cases were identified between 1 January 2009 and 1 March 2010, 50 of them from late July 2009(More)
Between August 2011 and January 2013, an outbreak of Salmonella enterica serovar Stanley (S. Stanley) infections affected 10 European Union (EU) countries, with a total of 710 cases recorded. Following an urgent inquiry in the Epidemic Intelligence Information System for food- and waterborne diseases (EPIS-FWD) on 29 June 2012, an international(More)

confirmed cases of hepatitis A virus (HAV) infections with subgenotype IB and identical RNA sequence, and 89 probable cases, have been reported in 14 EU/EFTA countries. All cases have a travel history to Egypt. Due to the fact that 15 of these cases, identified in three different countries, have identical sequences, a multistate outbreak has been confirmed(More)

A hybrid strain of enteroaggregative and Shiga toxin 2-producing Escherichia coli (EAEC-STEC) serotype O104:H4 strain caused a large outbreak of haemolytic uraemic syndrome and bloody diarrhoea in 2011 in Europe. Two surveys were performed in the European Union (EU) and European Economic Area (EEA) countries to assess their laboratory capabilities to detect(More)
